af43572ee5 Review feedback from @shawnxie999: even more rounding
- Round the initial total value computation upward, unless there is
  0-interest.
- Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
  computation to use it.
- Use adjustImpreciseNumber for LossUnrealized.
- Add some logging to computeLoanProperties.

020ea3f412 refactor: Update Conan dependencies: protobuf and grpc (#5589)
This PR updates protobuf and grpc to their latest versions. The latest protobuf version no longer requires patches, so we can use it directly from the official Conan Center Index, while the latest grpc still needed a patch, which was added to our own Conan Center Index fork in XRPLF/conan-center-index#8.

- In overpayment results, the management fee was being calculated twice:
  once as part of the value change, and as part of the fees paid.
  Exclude it from the value change.

43a6f10050 MPTTester::operator() parameter should be std::int64_t
- Originally defined as uint64_t, but the testIssuerLoan() test called
  it with a negative number, causing an overflow to a very large number
  that in some circumstances could be silently cast back to an int64_t,
  but might not be. I believe this is UB, and we don't want to rely on
  that.

- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
  allow for standalone testing, future development work, and potential
  bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
  appropriate.
- Refactors and improves several existing classes and functional areas,
  including Number, STAmount, STObject, json_value, Asset, directory
  handling, View helper functions, and unit test helpers.

2ed4047840 chore: Make conan lockfile generation commands into a script (#6085)
This change moves the lockfile instructions into a script, and instead of removing packages it sets the Conan home directory to a temporary directory.

There are several advantages, such as:
* Not affecting the user's Conan home directory, so there is no need to remove packages.
* Only the script needs to be run, rather than several commands.

a18b30b765 docs: Update instructions how to (re)generate conan.lock file (#6070)
This change updates the instructions for how to generate a Conan lockfile that is compatible with Linux, macOS, and Windows.

Whenever Conan dependencies change, the Conan lock file needs to be regenerated. However, different OSes have slightly different requirements, and thus require slightly different dependencies. Luckily a single `conan.lock` file can be used, as long as the union of dependencies is included.

The current instructions in the `BUILD.md` file are insufficient to regenerate the lock file such that it is compatible with all OSes, which this change addresses. The three profiles contain the bare minimum needed to generate the lockfile; it does not particularly matter whether the build type is Debug or Release, for instance.

973a105959 Review feedback: test coverage, round debt total
- Add some test cases to improve coverage, and exclude some lines from
  coverage.
- Rounds the Broker.DebtTotal to the Vault scale any time it is
  modified. This should reduce rounding errors.
- Ensure that no debt is left for the Broker after the last loan is
  deleted. This ensures that any accumulated rounding errors are
  resolved.

fd115cfc13 Address my review feedback on (#6017)
- Shortcut on issuer match in canTransfer.
- An asset can transfer if either trustline enabled rippling, so both
  must have it disabled for the transfer to fail with terNO_RIPPLE.
- Remove unnecessary asfDefaultRipple sets in unit tests.
- Add a new unit test helper class: testline, and a macro: THISLINE.
  When included as a parameter to Env::operator(), will include the line
  number of the transaction that didn't get the expected result. Works
  similarly to BEAST_EXPECT. I didn't do the same for the file name,
  because that can be deduced from the testcase name.

- "valid" means the value is <= Number::maxIntValue, which has been
  changed to maxMantissa / 100. A valid number could get bigger and be
  ok - such as when paying late interest on a loan.
- "representable" means the value is <= Number::maxMantissa. An
  unrepresentable number WILL be rounded or truncated.
- Adds a fourth level of enforcement: "compatible". It is used for
  converting XRP to Number (for AMM), and when doing explicit checks.
- "weak" will now throw if the number is unrepresentable.

aed8e2b166 Fill in payment computation shortages (#5941)
- Ensures a consistent fixed payment amount for the entire life of the
  loan, except the final payment, which is guaranteed to be the same or
  smaller.
- Convert some Loan structs to compute values that had need manual
  updates to stay consistent.
- Fail the transaction in `LoanPay` if it violates the Vault `assetsAvailable <=
  assetsTotal` invariant.
- Use constexpr to check that min mantissa value for Number and STAmount
  is a power of 10, and compute the max in terms of the min.
- Improve unit tests:
  - Use BrokerParameters and Loan Parameters instead of semi-global
    class values
  - In tests, check that the expected number of loan payments are made.
  - Add LoanBatch manual test to generate a set number of random loans,
    set them up, and pay them off.
  - Add LoanArbitrary manual test to run a single test with specific
    (hard-coded for now) parameters.
  - Add Number support to XRP_t.

  both non-zero, because both are used in the default amount
  calculations, which is the only place they're really meaningful.

- Add `Number::zero`, which is longer to type, but more readable than

    of payments included in the Amount and charges

    (including overpayments if applicable) hits this limit, stop
    processing more payments, but DO NOT FAIL.
- Fix the rounding in LoanSet for Guard 4 (sufficient computed payments)
- Tweak several test parameters to account for the new limits.

78ef800e30 Fix more problems introduced by 6adb2ec
- Renamed canSendToAccount to canWithdraw, because the semantics are
  a little different from a payment. Notably, if withdrawing to self,
  you can still include a destination tag.
- Simplified the interface to canWithdraw to just pass in the
  STTx.
- preflightDestinationAndTag is pretty pointless now, so removed it.

c179135e15 Fix the build and test errors introduced by the previous merge:
** Vault Invariants for Loan txs need to be fleshed out. **

- Give the appropriate Loan transactions vault modification privileges.
- Give the appropriate Loan transactions the ability to authorize
  (create in this case) MPTokens.
- Check that LoanManage does not leave Vault in an inconsistent state
  (AssetsAvailable > AssetsTotal). For IOU vaults, if the difference is
  dust, "round up".

23045fcbef Add support for extra transaction signature validation
- Restructures `STTx` signature checking code to be able to handle
  a `sigObject`, which may be the full transaction, or may be an object
  field containing a separate signature. Either way, the `sigObject` can
  be a single- or multi-sign signature.
- This is distinct from 550f90a75e (#5594), which changed the check in
  Transactor, which validates whether a given account is allowed to sign
  for the given transaction. This cryptographically checks the signature
  validity.

e1b234cc51 fix: Transaction sig checking functions do not get a full context
- Fixes a bug introduced by PR #5594, commit 550f90a75e, which
  introduced the concept of a "sigObject", in which the signature is
  checked without necessarily being the transaction.
- Fortunately, no code uses the "sigObject" as anything other than the
  transactor yet, so the bug is harmless for now.
- This fix removes the "PreclaimContext" from the parameter list, and
  adds only the individual parts needed by the function, none of which
  are the transaction.

1b295c7c00 Use Permission to check if a Transactor is enabled
- Adds a Permission::getTxFeature lookup function to find the
  controlling amendment for a Transactor, if any.
- Returns temDISABLED from preflight if there is an amendment and it's
  not enabled.
- Still need to go through and remove all the now-redundant isEnabled
  functions.

  the whole hex string first.
- Change PrettyAsset::scale_ back to a uint32 since the Number
  conversion elides any potential multiplication overflow.

- Mostly adding comments.
- Fixed some function parameter names that weren't updated after
  a copy/paste.
- LoanBrokerCoverWithdraw does not need to check for freeze when sending
  to the issuer.
- Reorder the fund transfer cases in LoanBrokerCoverWithdraw to make it
  clearer that some transfers are direct, and some use the payment
  engine.
- Only look up the vault ID once in LoanBrokerSet

9920037d13 Review feedback from @dangell7
- Cleaned up some of the `LEDGER_ENTRY` macros by eliding unnecessary
  parameters.
- Define the transaction privileges in one place (InvariantCheck.cpp).
- Give `EscrowFinish` the `mayAuthorizeMPT` privilege.
- Rename the test helper `expectLine` to `expectHolding` since
  it handles both trust lines and MPTs.
- Restructure the ""pseudo-account has 2 pseudo-account fields set"
  invariant test to loop over all defined pseudo-account fields.
- Fix `operator<<` for `PrettyAmount` to handle `MPTIssue`s.
- Add enforcement of the `AccountRootsDeletedClean` invariant if SAV is
  enabled, and clarify the comment for the pseudo-account field check.
- Delete the 100% redundant `ttMPTOKEN_ISSUANCE_SET` check in
  `ValidMPTIssuance`.

6d137e44dc Add Counterparty signing support
- Add a new parameter "signature_target" to "sign". Supports single and

- Skip account validation if this field is set, like multisigning.
- Unit tests demonstrating examples.

7dcc682e29 Make LoanSet.CounterpartySignature optional in the Tx layout
- Still required for the transaction to succeed (except inside a Batch,
  because the batch signers take care of that).
- Started adding tests for Loan-related RPC and low-level math checks.
  Currently only implemented "sign" on a LoanSet to verify it can be
  done.

162875616d Correct more issues related to 0-interest loans and some rounding issues
- Addresses FIND-012 from audit.
- If computePeriodicPaymentParts rounds the principal part to 0, add
  a small amount so that some principal is paid regardless of how
  extreme the loan parameters are. For XRP and MPTs, this just adds 1.
  For IOUs, compute an epsilon based on the scale of the original loan.
  (IOUs untested.)
  - Also move this function out of the detail namespace so direct unit
    tests can be written. (Pending.)
- Adds the testLoanPayComputePeriodicPaymentValidRateInvariant from
  auditors with some minor modifications.
- Fixes an assert that the periodic rate > 0, which won't be true if the
  loan interest rate is 0.

d58399d417 Correct handling of LoanBroker.DebtMaximum zero values
- Addresses FIND-003 from audit.
- Behavior changed to treat a DebtMaximum value of 0 to mean "no limit",
  as defined in spec.
- No need to add unit tests, because the previous commit covers 0, and
  tests already exist for non-zero limits.

9d1a23a811 Ensure Counterparty Signatures are properly handled by Batch tx
- Addresses FIND-001 from audit
- LoanSet::preflight will require Counterparty to be set (it's normally
  optional) for an inner batch transaction, because the checks are done
  before the LoanBroker object can be accessed.
- Adjust LoanSet::calculateBaseFee to not charge extra if an inner
  transaction.
- Adds a Loan-specific test to Batch_test.

- Add wrappers checkFrozen and checkDeepFrozen that return the
  appropriate TER code, so the Asset type doesn't have to be checked
  at every #*%@ing caller.
- Convert the Loan* transactors to use these functions.

527e0c916f Lending protocol implementation (XLS-0066)
- Add the LendingProtocol amendment
- Add Loan Broker and Loan ledger objects:
- Also add new SFields, Keylet functions, and an Invariant to verify no
  illegal field modification
- Update list of "constant" fields from spec
- Also add a general check for all object types for the type and index
  fields
- refactor: Check transaction flags in preflight0
- Adds a flagMask parameter to preflight1 so that it's impossible to
  forget to check flags.
- Also adds a short hash prefix to all Transactor log messages.
- refactor: Generalize Transactor preflight:
- Derived classes no longer need to explicitly check amendments, nor
  call into preflight1 or preflight2.
- implemeng LoanBrokerSet
- Transactions: LoanDelete, LoanManage, LoanDraw, LoanPay
- LoanBrokerSet creation mostly done. Need update.
- Also added a lookup table for pseudo account fields.
- Update changed field name.
- Modify modifiable fields in an update. Note there are only two.
- Add a node field to dirLink, defaulting sfOwnerNode, so other
  relationships can be updated.
- Create some helper classes for transaction fields
- Test that they work by converting some of the existing classes
- Finish creating helper classes for JTx fields
- Also change the pseudo account field lookup to a function that uses
  a switch
- Update tests, update pseudo-account checking
- Generalize some of the Invariant checks using macro files
  - Valid ledger entry type
  - Valid new account root and pseudo account check
- Enumerate transaction privileges for invariants
  - Allows them to be defined in transactions.macro instead of needing to
    scrutinize every existing Invariant class.
  - List is not necessarily comprehensive, but does cover every check
    where more than one transaction type is involved.
- Reserve a few values between Vault and Lending for future use
- Pseudo-account improvements
  - Define pseudo-account fields with an sfield flag
  - Pseudo-account invariant checks rules whenever a pseudo-account is
    created or modified.
- Move some helper functions.
- Check the regular key in the pseudo-transaction invariant check.
- Transactor::checkSign will always fail for a pseudo-account, so even
  if someone figures out how to get a good signature, it won't work.
- Fix account creation to check both amendments
- Add a validity range for sfDebtMaximum
- Change more "failed" messages. The goal here is to be able to search
  the log for "failed" and ONLY get test failures.
- NoModifiedUnmodifiableFields and ValidPseudoAccounts
- Move the Invariants_test class into the test namespace
- Clang wants an explicit ctor to emplace in a vector
- Refactor: Add a Transactor base function to make it easier to get the
  owner reserve increment as a fee.
- Refactor: Add an overload jtx::fee(increment) to pay an owner reserve.
- Initial implementation of LoanBrokerDelete
- Generalize the LoanBroker lifecycle test
- Refactor ApplyView::dirAdd to give access to low-level operations
  - Takes a page from #5362, which may turn out to be useful!
- Start writing Loan Broker invariants and tests
  - Specifically those mentioned for LoanBrokerDelete
- Move all detail namespaces to be under ripple
  - Avoids problems with namespace collisions / ambiguous symbol issues
    with unity builds, especially when adding or removing files.
- Add LoanBrokerCoverDeposit transaction
- Add LoanBrokerCoverWithdraw transaction
- Start writing tests for LoanBrokerCover*
- Add support for `Asset` and `MPTIssue` to some `jtx` helper classes
  and functions (`balance`, `expectLine`)
- Add support for pseudo-accounts to `jtx::Account` by allowing directly
  setting the AccountID without a matching key.
- Add Asset and MPTIssue support to more jtx objects / functions
  - Unfortunately, to work around some ambiguous symbol compilation
    errors, I had to change the implicit conversion from IOU to Asset to
    a conversion from IOU to PrettyAsset, and add a more explicit
    `asset()` function. This workaround only required changing two
    existing tests, so seems acceptable.
- Ensure that an account is not deleted with an XRP balance
  - Updates the AccountRootsDeletedClean invariant
- Finish up the Loan Broker tests
- Move inclusion of Transactor headers to transactions.macro
  - Only need to update in one place when adding a new transaction.
- Start implementing LoanSet transactor
  - Add some more values and functions to make it easier to work with
    basis point values / bips.
  - Fix several earlier mistakes.
- Generalize the check*Sign functions to support CounterParty
  - checkSign, checkSingleSign, and checkMultiSign in STTx and Transactor
- Start writing Loan tests
  - Required adding support for counterparty signature to jtx framework:
    arbitrary signature field destination, multiple signer callbacks
- Get Counterparty signing working
- Add more LoanSet unit tests, added LoanBroker LoanSequence field
  - LoanSequence will prevent loan key collisions
- Change Loan object indexing, fix several broken LoanSet unit tests
  - Loan objects will now only be indexed by LoanBrokerID and
    LoanSequence, which is a new field in LoanBroker. Also changes
    Loan.Sequence to Loan.LoanSequence to match up.
  - Several tests weren't working because of `PrettyAsset` scaling. Also,
    `PrettyAsset` calculations could overflow. Made that less likely by
    changing the type of `scale_`.
  - LoanSet will fail if an account tries to loan to itself.
- Ensure that an account is not deleted with a non-zero owner count
  - Updates the AccountRootsDeletedClean invariant
- Add unit tests to create a Loan successfully
  - Fix a few field initializations in LoanSet
- Refactor issuance validity check in VaultCreate
  - Utility function: canAddHolding
  - Call canAddHolding from any transactor that call addEmptyHolding
    (LoanBrokerSet, LoanSet)
- Start implementing LoanManage transaction
  - Also add a ValidLoan invariant
- Finish `LoanManage` functionality and tests, modulo LoanDraw/Pay
- Allow existing trust lines to loan brokers to be managed (by issuer)
- Implement LoanDelete, and fix a bunch of math errors in LoanManage
- Update to match latest spec: compute interest, LoanBroker reserves
- refactor: Define getFlagsMask in the base Transactor class
  - Returns tfUniversalMask for most transactors
  - Only transactors that use other flags need to override
- Implement LoanDraw, and made good progress on related tests
- Start implementing LoanPay transaction
- Implement LoanPay & most tests
- Also add an XRPL_ASSERT_PARTS, which splits the parts of the assert message
    so I don't have to remember the proper formatting.
Start writing LoanPay transaction tests

To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html),
which has to be updated every time dependencies change.

#### Conan lockfile
To achieve reproducible dependencies, we use [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
The `conan.lock` file in the repository contains a "snapshot" of the current dependencies.
It is implicitly used when running `conan` commands, you don't need to specify it.
You have to update this file every time you add a new dependency or change a revision or version of an existing dependency.
> [!NOTE]
> Conan uses local cache by default when creating a lockfile.
>
> To ensure, that lockfile creation works the same way on all developer machines, you should clear the local cache before creating a new lockfile.
To create a new lockfile, run the following commands in the repository root:
```bash
conan remove '*' --confirm
rm conan.lock
# This ensure that xrplf remote is the first to be consulted
conan remote add --force --index 0 xrplf https://conan.ripplex.io
conan lock create . -o '&:jemalloc=True' -o '&:rocksdb=True'
```
> [!NOTE]
> If some dependencies are exclusive for some OS, you may need to run the last command for them adding `--profile:all <PROFILE>`.

[ed25519](http://ed25519.cr.yp.to/) is an
[Elliptic Curve Digital Signature Algortithm](http://en.wikipedia.org/wiki/Elliptic_Curve_DSA),
developed by [Dan Bernstein](http://cr.yp.to/djb.html),
[Niels Duif](http://www.nielsduif.nl/),
[Tanja Lange](http://hyperelliptic.org/tanja),
[Peter Schwabe](http://www.cryptojedi.org/users/peter/),
and [Bo-Yin Yang](http://www.iis.sinica.edu.tw/pages/byyang/).
This project provides performant, portable 32-bit & 64-bit implementations. All implementations are
of course constant time in regard to secret data.
#### Performance
SSE2 code and benches have not been updated yet. I will do those next.
Compilers versions are gcc 4.6.3, icc 13.1.1, clang 3.4-1~exp1.
Batch verification time (in parentheses) is the average time per 1 verification in a batch of 64 signatures. Counts are in thousands of cycles.
Note that SSE2 performance may be less impressive on AMD & older CPUs with slower SSE ops!
Visual Studio performance for `ge25519_scalarmult_base_niels` will lag behind a bit until optimized assembler versions of `ge25519_scalarmult_base_choose_niels`
are made.

#### Compilation
No configuration is needed **if you are compiling against OpenSSL**.
##### Hash Options
If you are not compiling aginst OpenSSL, you will need a hash function.
To use a simple/**slow** implementation of SHA-512, use `-DED25519_REFHASH` when compiling `ed25519.c`.
This should never be used except to verify the code works when OpenSSL is not available.
To use a custom hash function, use `-DED25519_CUSTOMHASH` when compiling `ed25519.c` and put your
custom hash implementation in ed25519-hash-custom.h. The hash must have a 512bit digest and implement
struct ed25519_hash_context;
void ed25519_hash_init(ed25519_hash_context *ctx);
void ed25519_hash_update(ed25519_hash_context *ctx, const uint8_t *in, size_t inlen);
void ed25519_hash_final(ed25519_hash_context *ctx, uint8_t *hash);
void ed25519_hash(uint8_t *hash, const uint8_t *in, size_t inlen);
##### Random Options
If you are not compiling aginst OpenSSL, you will need a random function for batch verification.
To use a custom random function, use `-DED25519_CUSTOMRANDOM` when compiling `ed25519.c` and put your
custom hash implementation in ed25519-randombytes-custom.h. The random function must implement:
void ED25519_FN(ed25519_randombytes_unsafe) (void *p, size_t len);
Use `-DED25519_TEST` when compiling `ed25519.c` to use a deterministically seeded, non-thread safe CSPRNG
variant of Bob Jenkins [ISAAC](http://en.wikipedia.org/wiki/ISAAC_%28cipher%29)
##### Minor options
Use `-DED25519_INLINE_ASM` to disable the use of custom assembler routines and instead rely on portable C.
Use `-DED25519_FORCE_32BIT` to force the use of 32 bit routines even when compiling for 64 bit.
##### 32-bit
gcc ed25519.c -m32 -O3 -c
##### 64-bit
gcc ed25519.c -m64 -O3 -c
##### SSE2
gcc ed25519.c -m32 -O3 -c -DED25519_SSE2 -msse2
gcc ed25519.c -m64 -O3 -c -DED25519_SSE2
clang and icc are also supported
#### Usage
To use the code, link against `ed25519.o -mbits` and:
#include "ed25519.h"
Add `-lssl -lcrypto` when using OpenSSL (Some systems don't need -lcrypto? It might be trial and error).
To generate a private key, simply generate 32 bytes from a secure
cryptographic source:
ed25519_secret_key sk;
randombytes(sk, sizeof(ed25519_secret_key));
To generate a public key:
ed25519_public_key pk;
ed25519_publickey(sk, pk);
To sign a message:
ed25519_signature sig;
ed25519_sign(message, message_len, sk, pk, signature);
To verify a signature:
int valid = ed25519_sign_open(message, message_len, pk, signature) == 0;
To batch verify signatures:
const unsigned char *mp[num] = {message1, message2..}
size_t ml[num] = {message_len1, message_len2..}
const unsigned char *pkp[num] = {pk1, pk2..}
const unsigned char *sigp[num] = {signature1, signature2..}
int valid[num]
/* valid[i] will be set to 1 if the individual signature was valid, 0 otherwise */
int all_valid = ed25519_sign_open_batch(mp, ml, pkp, sigp, num, valid) == 0;
**Note**: Batch verification uses `ed25519_randombytes_unsafe`, implemented in
`ed25519-randombytes.h`, to generate random scalars for the verification code.
The default implementation now uses OpenSSLs `RAND_bytes`.
Unlike the [SUPERCOP](http://bench.cr.yp.to/supercop.html) version, signatures are
not appended to messages, and there is no need for padding in front of messages.
Additionally, the secret key does not contain a copy of the public key, so it is
32 bytes instead of 64 bytes, and the public key must be provided to the signing
function.
##### Curve25519
Curve25519 public keys can be generated thanks to
[Adam Langley](http://www.imperialviolet.org/2013/05/10/fastercurve25519.html)
leveraging Ed25519's precomputed basepoint scalar multiplication.
curved25519_key sk, pk;
randombytes(sk, sizeof(curved25519_key));
curved25519_scalarmult_basepoint(pk, sk);
Note the name is curved25519, a combination of curve and ed25519, to prevent
name clashes. Performance is slightly faster than short message ed25519
signing due to both using the same code for the scalar multiply.
#### Testing
Fuzzing against reference implemenations is now available. See [fuzz/README](fuzz/README.md).
Building `ed25519.c` with `-DED25519_TEST` and linking with `test.c` will run basic sanity tests
and benchmark each function. `test-batch.c` has been incorporated in to `test.c`.
`test-internals.c` is standalone and built the same way as `ed25519.c`. It tests the math primitives
with extreme values to ensure they function correctly. SSE2 is now supported.

This code fuzzes ed25519-donna (and optionally ed25519-donna-sse2) against the ref10 implementations of
[curve25519](https://github.com/floodyberry/supercop/tree/master/crypto_scalarmult/curve25519/ref10) and
[ed25519](https://github.com/floodyberry/supercop/tree/master/crypto_sign/ed25519/ref10).
Curve25519 tests that generating a public key from a secret key
# Building
## *nix + PHP
`php build-nix.php (required parameters) (optional parameters)`
Required parameters:
* `--function=[curve25519,ed25519]`
* `--bits=[32,64]`
Optional parameters:
* `--with-sse2`
Also fuzz against ed25519-donna-sse2
* `--with-openssl`
Build with OpenSSL's SHA-512.
Default: Reference SHA-512 implementation (slow!)
* `--compiler=[gcc,clang,icc]`
Default: gcc
* `--no-asm`
Do not use platform specific assembler
example:
php build-nix.php --bits=64 --function=ed25519 --with-sse2 --compiler=icc
## Windows
Create a project with access to the ed25519 files.
If you are not using OpenSSL, add the `ED25519_REFHASH` define to the projects
"Properties/Preprocessor/Preprocessor Definitions" option
Add the following files to the project:
* `fuzz/curve25519-ref10.c`
* `fuzz/ed25519-ref10.c`
* `fuzz/ed25519-donna.c`
* `fuzz/ed25519-donna-sse2.c` (optional)
* `fuzz-[curve25519/ed25519].c` (depending on which you want to fuzz)
If you are also fuzzing against ed25519-donna-sse2, add the `ED25519_SSE2` define for `fuzz-[curve25519/ed25519].c` under
its "Properties/Preprocessor/Preprocessor Definitions" option.
# Running
If everything agrees, the program will only output occasional status dots (every 0x1000 passes)
and a 64bit progress count (every 0x20000 passes):
fuzzing: ref10 curved25519 curved25519-sse2
................................ [0000000000020000]
................................ [0000000000040000]

................................ [00000000000a0000]
................................ [00000000000c0000]
If any of the implementations do not agree with the ref10 implementation, the program will dump
the random data that was used, the data generated by the ref10 implementation, and diffs of the
ed25519-donna data against the ref10 data.

Introducing the 128 bit r scalars to the heap _before_ the largest scalar
fits in to 128 bits alters the heap shape and produces a different,
yet still neutral/valid y/z value.
This was the value of introducing the r scalars when the largest scalar fit
in to 135-256 bits. You can produce it with amd64-64-24k / amd64-51-32k
with the random sequence used in the first pass by changing
unsigned long long hlen=((npoints+1)/2)|1;
to
unsigned long long hlen=npoints;

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [0.6.0] - 2024-11-04
#### Added
- New module `musig` implements the MuSig2 multisignature scheme according to the [BIP 327 specification](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki). See:
- Header file `include/secp256k1_musig.h` which defines the new API.
- Document `doc/musig.md` for further notes on API usage.
- Usage example `examples/musig.c`.
- New CMake variable `SECP256K1_APPEND_LDFLAGS` for appending linker flags to the build command.
#### Changed
- API functions now use a significantly more robust method to clear secrets from the stack before returning. However, secret clearing remains a best-effort security measure and cannot guarantee complete removal.
- Any type `secp256k1_foo` can now be forward-declared using `typedef struct secp256k1_foo secp256k1_foo;` (or also `struct secp256k1_foo;` in C++).
- Organized CMake build artifacts into dedicated directories (`bin/` for executables, `lib/` for libraries) to improve build output structure and Windows shared library compatibility.
#### Removed
- Removed the `secp256k1_scratch_space` struct and its associated functions `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` because the scratch space was unused in the API.
#### ABI Compatibility
The symbols `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` were removed.
Otherwise, the library maintains backward compatibility with versions 0.3.x through 0.5.x.
## [0.5.1] - 2024-08-01
#### Added
- Added usage example for an ElligatorSwift key exchange.
#### Changed
- The default size of the precomputed table for signing was changed from 22 KiB to 86 KiB. The size can be changed with the configure option `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake).
- "auto" is no longer an accepted value for the `--with-ecmult-window` and `--with-ecmult-gen-kb` configure options (this also applies to `SECP256K1_ECMULT_WINDOW_SIZE` and `SECP256K1_ECMULT_GEN_KB` in CMake). To achieve the same configuration as previously provided by the "auto" value, omit setting the configure option explicitly.
#### Fixed
- Fixed compilation when the extrakeys module is disabled.
#### ABI Compatibility
The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x.
## [0.5.0] - 2024-05-06
#### Added
- New function `secp256k1_ec_pubkey_sort` that sorts public keys using lexicographic (of compressed serialization) order.
#### Changed
- The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations.
- The related configure option `--ecmult-gen-precision` was replaced with `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake).
- This changes the supported precomputed table sizes for these operations. The new supported sizes are 2 KiB, 22 KiB, or 86 KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB).
#### ABI Compatibility
The ABI is backward compatible with versions 0.4.x and 0.3.x.
## [0.4.1] - 2023-12-21
#### Changed
- The point multiplication algorithm used for ECDH operations (module `ecdh`) was replaced with a slightly faster one.
- Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (`--with-asm=x86_64` in GNU Autotools, `-DSECP256K1_ASM=x86_64` in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for `secp256k1_ecdsa_verify` and `secp256k1_schnorrsig_verify`.
#### ABI Compatibility
The ABI is backward compatible with versions 0.4.0 and 0.3.x.
## [0.4.0] - 2023-09-04
#### Added
- New module `ellswift` implements ElligatorSwift encoding for public keys and x-only Diffie-Hellman key exchange for them.
ElligatorSwift permits representing secp256k1 public keys as 64-byte arrays which cannot be distinguished from uniformly random. See:
- Header file `include/secp256k1_ellswift.h` which defines the new API.
- Document `doc/ellswift.md` which explains the mathematical background of the scheme.
- The [paper](https://eprint.iacr.org/2022/759) on which the scheme is based.
- We now test the library with unreleased development snapshots of GCC and Clang. This gives us an early chance to catch miscompilations and constant-time issues introduced by the compiler (such as those that led to the previous two releases).
#### Fixed
- Fixed symbol visibility in Windows DLL builds, where three internal library symbols were wrongly exported.
#### Changed
- When consuming libsecp256k1 as a static library on Windows, the user must now define the `SECP256K1_STATIC` macro before including `secp256k1.h`.
#### ABI Compatibility
This release is backward compatible with the ABI of 0.3.0, 0.3.1, and 0.3.2. Symbol visibility is now believed to be handled properly on supported platforms and is now considered to be part of the ABI. Please report any improperly exported symbols as a bug.
## [0.3.2] - 2023-05-13
We strongly recommend updating to 0.3.2 if you use or plan to use GCC >=13 to compile libsecp256k1. When in doubt, check the GCC version using `gcc -v`.
#### Security
- Module `ecdh`: Fix "constant-timeness" issue with GCC 13.1 (and potentially future versions of GCC) that could leave applications using libsecp256k1's ECDH module vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow during ECDH computations when libsecp256k1 is compiled with GCC 13.1.
#### Fixed
- Fixed an old bug that permitted compilers to potentially output bad assembly code on x86_64. In theory, it could lead to a crash or a read of unrelated memory, but this has never been observed on any compilers so far.
#### Changed
- Various improvements and changes to CMake builds. CMake builds remain experimental.
- Made API versioning consistent with GNU Autotools builds.
- Switched to `BUILD_SHARED_LIBS` variable for controlling whether to build a static or a shared library.
- Added `SECP256K1_INSTALL` variable for the controlling whether to install the build artefacts.
- Renamed asm build option `arm` to `arm32`. Use `--with-asm=arm32` instead of `--with-asm=arm` (GNU Autotools), and `-DSECP256K1_ASM=arm32` instead of `-DSECP256K1_ASM=arm` (CMake).
#### ABI Compatibility
The ABI is compatible with versions 0.3.0 and 0.3.1.
## [0.3.1] - 2023-04-10
We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to compile libsecp256k1, e.g., Xcode >=14 on macOS has Clang >=14. When in doubt, check the Clang version using `clang -v`.
#### Security
- Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14.
#### Added
- Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases.
#### Changed
- Increased minimum required CMake version to 3.13. CMake builds remain experimental.
#### ABI Compatibility
The ABI is compatible with version 0.3.0.
## [0.3.0] - 2023-03-08
#### Added
- Added experimental support for CMake builds. Traditional GNU Autotools builds (`./configure` and `make`) remain fully supported.
- Usage examples: Added a recommended method for securely clearing sensitive data, e.g., secret keys, from memory.
- Tests: Added a new test binary `noverify_tests`. This binary runs the tests without some additional checks present in the ordinary `tests` binary and is thereby closer to production binaries. The `noverify_tests` binary is automatically run as part of the `make check` target.
#### Fixed
- Fixed declarations of API variables for MSVC (`__declspec(dllimport)`). This fixes MSVC builds of programs which link against a libsecp256k1 DLL dynamically and use API variables (and not only API functions). Unfortunately, the MSVC linker now will emit warning `LNK4217` when trying to link against libsecp256k1 statically. Pass `/ignore:4217` to the linker to suppress this warning.
#### Changed
- Forbade cloning or destroying `secp256k1_context_static`. Create a new context instead of cloning the static context. (If this change breaks your code, your code is probably wrong.)
- Forbade randomizing (copies of) `secp256k1_context_static`. Randomizing a copy of `secp256k1_context_static` did not have any effect and did not provide defense-in-depth protection against side-channel attacks. Create a new context if you want to benefit from randomization.
#### Removed
- Removed the configuration header `src/libsecp256k1-config.h`. We recommend passing flags to `./configure` or `cmake` to set configuration options (see `./configure --help` or `cmake -LH`). If you cannot or do not want to use one of the supported build systems, pass configuration flags such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG` manually to the compiler (see the file `configure.ac` for supported flags).
#### ABI Compatibility
Due to changes in the API regarding `secp256k1_context_static` described above, the ABI is *not* compatible with previous versions.
## [0.2.0] - 2022-12-12
#### Added
- Added usage examples for common use cases in a new `examples/` directory.
- Added `secp256k1_selftest`, to be used in conjunction with `secp256k1_context_static`.
- Added support for 128-bit wide multiplication on MSVC for x86_64 and arm64, giving roughly a 20% speedup on those platforms.
#### Changed
- Enabled modules `schnorrsig`, `extrakeys` and `ecdh` by default in `./configure`.
- The `secp256k1_nonce_function_rfc6979` nonce function, used by default by `secp256k1_ecdsa_sign`, now reduces the message hash modulo the group order to match the specification. This only affects improper use of ECDSA signing API.
#### Deprecated
- Deprecated context flags `SECP256K1_CONTEXT_VERIFY` and `SECP256K1_CONTEXT_SIGN`. Use `SECP256K1_CONTEXT_NONE` instead.
- Renamed `secp256k1_context_no_precomp` to `secp256k1_context_static`.
- Module `schnorrsig`: renamed `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`.
#### ABI Compatibility
Since this is the first release, we do not compare application binary interfaces.
However, there are earlier unreleased versions of libsecp256k1 that are *not* ABI compatible with this version.
## [0.1.0] - 2013-03-05 to 2021-12-25
This version was in fact never released.
The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6).
Therefore, this version number does not uniquely identify a set of source files.

# Contributing to libsecp256k1
## Scope
libsecp256k1 is a library for elliptic curve cryptography on the curve secp256k1, not a general-purpose cryptography library.
The library primarily serves the needs of the Bitcoin Core project but provides additional functionality for the benefit of the wider Bitcoin ecosystem.
## Adding new functionality or modules
The libsecp256k1 project welcomes contributions in the form of new functionality or modules, provided they are within the project's scope.
It is the responsibility of the contributors to convince the maintainers that the proposed functionality is within the project's scope, high-quality and maintainable.
Contributors are recommended to provide the following in addition to the new code:
* **Specification:**
A specification can help significantly in reviewing the new code as it provides documentation and context.
It may justify various design decisions, give a motivation and outline security goals.
If the specification contains pseudocode, a reference implementation or test vectors, these can be used to compare with the proposed libsecp256k1 code.
* **Security Arguments:**
In addition to a defining the security goals, it should be argued that the new functionality meets these goals.
Depending on the nature of the new functionality, a wide range of security arguments are acceptable, ranging from being "obviously secure" to rigorous proofs of security.
* **Relevance Arguments:**
The relevance of the new functionality for the Bitcoin ecosystem should be argued by outlining clear use cases.
These are not the only factors taken into account when considering to add new functionality.
The proposed new libsecp256k1 code must be of high quality, including API documentation and tests, as well as featuring a misuse-resistant API design.
We recommend reaching out to other contributors (see [Communication Channels](#communication-channels)) and get feedback before implementing new functionality.
## Communication channels
Most communication about libsecp256k1 occurs on the GitHub repository: in issues, pull request or on the discussion board.
Additionally, there is an IRC channel dedicated to libsecp256k1, with biweekly meetings (see channel topic).
The channel is `#secp256k1` on Libera Chat.
The easiest way to participate on IRC is with the web client, [web.libera.chat](https://web.libera.chat/#secp256k1).
Chat history logs can be found at https://gnusha.org/secp256k1/.
## Contributor workflow & peer review
The Contributor Workflow & Peer Review in libsecp256k1 are similar to Bitcoin Core's workflow and review processes described in its [CONTRIBUTING.md](https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md).
### Coding conventions
In addition, libsecp256k1 tries to maintain the following coding conventions:
* No runtime heap allocation (e.g., no `malloc`) unless explicitly requested by the caller (via `secp256k1_context_create` or `secp256k1_scratch_space_create`, for example). Moreover, it should be possible to use the library without any heap allocations.
* The tests should cover all lines and branches of the library (see [Test coverage](#coverage)).
* Operations involving secret data should be tested for being constant time with respect to the secrets (see [src/ctime_tests.c](src/ctime_tests.c)).
* Local variables containing secret data should be cleared explicitly to try to delete secrets from memory.
* Use `secp256k1_memcmp_var` instead of `memcmp` (see [#823](https://github.com/bitcoin-core/secp256k1/issues/823)).
* As a rule of thumb, the default values for configuration options should target standard desktop machines and align with Bitcoin Core's defaults, and the tests should mostly exercise the default configuration (see [#1549](https://github.com/bitcoin-core/secp256k1/issues/1549#issuecomment-2200559257)).
#### Style conventions
* Commits should be atomic and diffs should be easy to read. For this reason, do not mix any formatting fixes or code moves with actual code changes. Make sure each individual commit is hygienic: that it builds successfully on its own without warnings, errors, regressions, or test failures.
* New code should adhere to the style of existing, in particular surrounding, code. Other than that, we do not enforce strict rules for code formatting.
* The code conforms to C89. Most notably, that means that only `/* ... */` comments are allowed (no `//` line comments). Moreover, any declarations in a `{ ... }` block (e.g., a function) must appear at the beginning of the block before any statements. When you would like to declare a variable in the middle of a block, you can open a new block:
```C
void secp256k_foo(void) {
unsigned int x; /* declaration */
int y = 2*x; /* declaration */
x = 17; /* statement */
{
int a, b; /* declaration */
a = x + y; /* statement */
secp256k_bar(x, &b); /* statement */
}
}
```
* Use `unsigned int` instead of just `unsigned`.
* Use `void *ptr` instead of `void* ptr`.
* Arguments of the publicly-facing API must have a specific order defined in [include/secp256k1.h](include/secp256k1.h).
* User-facing comment lines in headers should be limited to 80 chars if possible.
* All identifiers in file scope should start with `secp256k1_`.
* Avoid trailing whitespace.
### Tests
#### Coverage
This library aims to have full coverage of reachable lines and branches.
To create a test coverage report, configure with `--enable-coverage` (use of GCC is necessary):
$ ./configure --enable-coverage
Run the tests:
$ make check
To create a report, `gcovr` is recommended, as it includes branch coverage reporting:
$ gcovr --exclude 'src/bench*' --print-summary
To create a HTML report with coloured and annotated source code:
$ mkdir -p coverage
$ gcovr --exclude 'src/bench*' --html --html-details -o coverage/coverage.html
#### Exhaustive tests
There are tests of several functions in which a small group replaces secp256k1.
These tests are *exhaustive* since they provide all elements and scalars of the small group as input arguments (see [src/tests_exhaustive.c](src/tests_exhaustive.c)).
### Benchmarks
See `src/bench*.c` for examples of benchmarks.

libsecp256k1
============
![Dependencies: None](https://img.shields.io/badge/dependencies-none-success)
[![irc.libera.chat #secp256k1](https://img.shields.io/badge/irc.libera.chat-%23secp256k1-success)](https://web.libera.chat/#secp256k1)
High-performance high-assurance C library for digital signatures and other cryptographic primitives on the secp256k1 elliptic curve.
This library is intended to be the highest quality publicly available library for cryptography on the secp256k1 curve. However, the primary focus of its development has been for usage in the Bitcoin system and usage unlike Bitcoin's may be less well tested, verified, or suffer from a less well thought out interface. Correct usage requires some care and consideration that the library is fit for your application's purpose.
Features:
* secp256k1 ECDSA signing/verification and key generation.
* Additive and multiplicative tweaking of secret/public keys.
* Serialization/parsing of secret keys, public keys, signatures.
* Constant time, constant memory access signing and public key generation.
* Derandomized ECDSA (via RFC6979 or with a caller provided function.)
* Very efficient implementation.
* Suitable for embedded systems.
* No runtime dependencies.
* Optional module for public key recovery.
* Optional module for ECDH key exchange.
* Optional module for Schnorr signatures according to [BIP-340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki).
* Optional module for ElligatorSwift key exchange according to [BIP-324](https://github.com/bitcoin/bips/blob/master/bip-0324.mediawiki).
* Optional module for MuSig2 Schnorr multi-signatures according to [BIP-327](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki).
Implementation details
----------------------
* General
* No runtime heap allocation.
* Extensive testing infrastructure.
* Structured to facilitate review and analysis.
* Intended to be portable to any system with a C89 compiler and uint64_t support.
* No use of floating types.
* Expose only higher level interfaces to minimize the API surface and improve application security. ("Be difficult to use insecurely.")
* Field operations
* Optimized implementation of arithmetic modulo the curve's field size (2^256 - 0x1000003D1).
* Using 5 52-bit limbs
* Using 10 26-bit limbs (including hand-optimized assembly for 32-bit ARM, by Wladimir J. van der Laan).
* This is an experimental feature that has not received enough scrutiny to satisfy the standard of quality of this library but is made available for testing and review by the community.
* Scalar operations
* Optimized implementation without data-dependent branches of arithmetic modulo the curve's order.
* Using 4 64-bit limbs (relying on __int128 support in the compiler).
* Using 8 32-bit limbs.
* Modular inverses (both field elements and scalars) based on [safegcd](https://gcd.cr.yp.to/index.html) with some modifications, and a variable-time variant (by Peter Dettman).
* Group operations
* Point addition formula specifically simplified for the curve equation (y^2 = x^3 + 7).
* Use addition between points in Jacobian and affine coordinates where possible.
* Use a unified addition/doubling formula where necessary to avoid data-dependent branches.
* Point/x comparison without a field inversion by comparison in the Jacobian coordinate space.
* Point multiplication for verification (a*P + b*G).
* Use wNAF notation for point multiplicands.
* Use a much larger window for multiples of G, using precomputed multiples.
* Use Shamir's trick to do the multiplication with the public key and the generator simultaneously.
* Use secp256k1's efficiently-computable endomorphism to split the P multiplicand into 2 half-sized ones.
* Point multiplication for signing
* Use a precomputed table of multiples of powers of 16 multiplied with the generator, so general multiplication becomes a series of additions.
* Intended to be completely free of timing sidechannels for secret-key operations (on reasonable hardware/toolchains)
* Access the table with branch-free conditional moves so memory access is uniform.
* No data-dependent branches
* Optional runtime blinding which attempts to frustrate differential power analysis.
* The precomputed tables add and eventually subtract points for which no known scalar (secret key) is known, preventing even an attacker with control over the secret key used to control the data internally.
Building with Autotools
-----------------------
$ ./autogen.sh
$ ./configure
$ make
$ make check # run the test suite
$ sudo make install # optional
To compile optional modules (such as Schnorr signatures), you need to run `./configure` with additional flags (such as `--enable-module-schnorrsig`). Run `./configure --help` to see the full list of available flags.
Building with CMake (experimental)
----------------------------------
To maintain a pristine source tree, CMake encourages to perform an out-of-source build by using a separate dedicated build tree.
### Building on POSIX systems
$ mkdir build && cd build
$ cmake ..
$ cmake --build .
$ ctest # run the test suite
$ sudo cmake --install . # optional
To compile optional modules (such as Schnorr signatures), you need to run `cmake` with additional flags (such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG=ON`). Run `cmake .. -LH` to see the full list of available flags.
### Cross compiling
To alleviate issues with cross compiling, preconfigured toolchain files are available in the `cmake` directory.
For example, to cross compile for Windows:
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/x86_64-w64-mingw32.toolchain.cmake
To cross compile for Android with [NDK](https://developer.android.com/ndk/guides/cmake) (using NDK's toolchain file, and assuming the `ANDROID_NDK_ROOT` environment variable has been set):
$ cmake .. -DCMAKE_TOOLCHAIN_FILE="${ANDROID_NDK_ROOT}/build/cmake/android.toolchain.cmake" -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=28
### Building on Windows
To build on Windows with Visual Studio, a proper [generator](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html#visual-studio-generators) must be specified for a new build tree.
The following example assumes using of Visual Studio 2022 and CMake v3.21+.
In "Developer Command Prompt for VS 2022":
>cmake -G "Visual Studio 17 2022" -A x64 -S . -B build
>cmake --build build --config RelWithDebInfo
Usage examples
-----------
Usage examples can be found in the [examples](examples) directory. To compile them you need to configure with `--enable-examples`.
* [ECDSA example](examples/ecdsa.c)
* [Schnorr signatures example](examples/schnorr.c)
* [Deriving a shared secret (ECDH) example](examples/ecdh.c)
* [ElligatorSwift key exchange example](examples/ellswift.c)
To compile the Schnorr signature and ECDH examples, you also need to configure with `--enable-module-schnorrsig` and `--enable-module-ecdh`.
Benchmark
------------
If configured with `--enable-benchmark` (which is the default), binaries for benchmarking the libsecp256k1 functions will be present in the root directory after the build.
To print the benchmark result to the command line:
$ ./bench_name
To create a CSV file for the benchmark result :
$ ./bench_name | sed '2d;s/ \{1,\}//g' > bench_name.csv

# generate entire wrapper executables (instead of simple wrapper scripts as on Unix) to ensure

/* This file defines a function that parses DER with various errors and
* violations. This is not a part of the library itself, because the allowed
* violations are chosen arbitrarily and do not follow or establish any
* standard.
*
* In many places it matters that different implementations do not only accept
* the same set of valid signatures, but also reject the same set of signatures.
* The only means to accomplish that is by strictly obeying a standard, and not
* accepting anything else.
*
* Nonetheless, sometimes there is a need for compatibility with systems that
* use signatures which do not strictly obey DER. The snippet below shows how
* certain violations are easily supported. You may need to adapt it.
*
* Do not use this for new systems. Use well-defined DER or compact signatures
* instead if you have the choice (see secp256k1_ecdsa_signature_parse_der and
* secp256k1_ecdsa_signature_parse_compact).
*
* The supported violations are:
* - All numbers are parsed as nonnegative integers, even though X.609-0207
* section 8.3.3 specifies that integers are always encoded as two's
* complement.
* - Integers can have length 0, even though section 8.3.1 says they can't.
* - Integers with overly long padding are accepted, violation section
* 8.3.2.
* - 127-byte long length descriptors are accepted, even though section
* 8.1.3.5.c says that they are not.
* - Trailing garbage data inside or after the signature is ignored.
* - The length descriptor of the sequence is ignored.
*
* Compared to for example OpenSSL, many violations are NOT supported:
* - Using overly long tag descriptors for the sequence or integers inside,
* violating section 8.1.2.2.
* - Encoding primitive integers as constructed values, violating section
* 8.3.1.

## 1. Introduction
The `ellswift` module effectively introduces a new 64-byte public key format, with the property
that (uniformly random) public keys can be encoded as 64-byte arrays which are computationally
indistinguishable from uniform byte arrays. The module provides functions to convert public keys
from and to this format, as well as convenience functions for key generation and ECDH that operate
directly on ellswift-encoded keys.
The encoding consists of the concatenation of two (32-byte big endian) encoded field elements $u$
and $t.$ Together they encode an x-coordinate on the curve $x$, or (see further) a full point $(x, y)$ on
the curve.
**Decoding** consists of decoding the field elements $u$ and $t$ (values above the field size $p$
are taken modulo $p$), and then evaluating $F_u(t)$, which for every $u$ and $t$ results in a valid
x-coordinate on the curve. The functions $F_u$ will be defined in [Section 2](#2-the-decoding-function).
**Encoding** a given $x$ coordinate is conceptually done as follows:
* Loop:
* Pick a uniformly random field element $u.$
* Compute the set $L = F_u^{-1}(x)$ of $t$ values for which $F_u(t) = x$, which may have up to *8* elements.
* With probability $1 - \dfrac{\\#L}{8}$, restart the loop.
* Select a uniformly random $t \in L$ and return $(u, t).$
This is the *ElligatorSwift* algorithm, here given for just x-coordinates. An extension to full
$(x, y)$ points will be given in [Section 4](#4-encoding-and-decoding-full-x-y-coordinates).
The algorithm finds a uniformly random $(u, t)$ among (almost all) those
for which $F_u(t) = x.$ Section 3.2 in the paper proves that the number of such encodings for
almost all x-coordinates on the curve (all but at most 39) is close to two times the field size
(specifically, it lies in the range $2q \pm (22\sqrt{q} + O(1))$, where $q$ is the size of the field).
## 2. The decoding function
First some definitions:
* $\mathbb{F}$ is the finite field of size $q$, of characteristic 5 or more, and $q \equiv 1 \mod 3.$
* For `secp256k1`, $q = 2^{256} - 2^{32} - 977$, which satisfies that requirement.
* Let $E$ be the elliptic curve of points $(x, y) \in \mathbb{F}^2$ for which $y^2 = x^3 + ax + b$, with $a$ and $b$
public constants, for which $\Delta_E = -16(4a^3 + 27b^2)$ is a square, and at least one of $(-b \pm \sqrt{-3 \Delta_E} / 36)/2$ is a square.
This implies that the order of $E$ is either odd, or a multiple of *4*.
If $a=0$, this condition is always fulfilled.
* For `secp256k1`, $a=0$ and $b=7.$
* Let the function $g(x) = x^3 + ax + b$, so the $E$ curve equation is also $y^2 = g(x).$
* Let the function $h(x) = 3x^3 + 4a.$
* Define $V$ as the set of solutions $(x_1, x_2, x_3, z)$ to $z^2 = g(x_1)g(x_2)g(x_3).$
* Define $S_u$ as the set of solutions $(X, Y)$ to $X^2 + h(u)Y^2 = -g(u)$ and $Y \neq 0.$
* $P_u$ is a function from $\mathbb{F}$ to $S_u$ that will be defined below.
* $\psi_u$ is a function from $S_u$ to $V$ that will be defined below.
**Note**: In the paper:
* $F_u$ corresponds to $F_{0,u}$ there.
* $P_u(t)$ is called $P$ there.
* All $S_u$ sets together correspond to $S$ there.
* All $\psi_u$ functions together (operating on elements of $S$) correspond to $\psi$ there.
Note that for $V$, the left hand side of the equation $z^2$ is square, and thus the right
hand must also be square. As multiplying non-squares results in a square in $\mathbb{F}$,
out of the three right-hand side factors an even number must be non-squares.
This implies that exactly *1* or exactly *3* out of
$\\{g(x_1), g(x_2), g(x_3)\\}$ must be square, and thus that for any $(x_1,x_2,x_3,z) \in V$,
at least one of $\\{x_1, x_2, x_3\\}$ must be a valid x-coordinate on $E.$ There is one exception
to this, namely when $z=0$, but even then one of the three values is a valid x-coordinate.
**Define** the decoding function $F_u(t)$ as:
* Let $(x_1, x_2, x_3, z) = \psi_u(P_u(t)).$
* Return the first element $x$ of $(x_3, x_2, x_1)$ which is a valid x-coordinate on $E$ (i.e., $g(x)$ is square).
$P_u(t) = (X(u, t), Y(u, t))$, where:
$$
\begin{array}{lcl}
X(u, t) & = & \left\\{\begin{array}{ll}
\dfrac{g(u) - t^2}{2t} & a = 0 \\
\dfrac{g(u) + h(u)(Y_0(u) - X_0(u)t)^2}{X_0(u)(1 + h(u)t^2)} & a \neq 0
\end{array}\right. \\
Y(u, t) & = & \left\\{\begin{array}{ll}
\dfrac{X(u, t) + t}{u \sqrt{-3}} = \dfrac{g(u) + t^2}{2tu\sqrt{-3}} & a = 0 \\
Y_0(u) + t(X(u, t) - X_0(u)) & a \neq 0
\end{array}\right.
\end{array}
$$
$P_u(t)$ is defined:
* For $a=0$, unless:
* $u = 0$ or $t = 0$ (division by zero)
* $g(u) = -t^2$ (would give $Y=0$).
* For $a \neq 0$, unless:
* $X_0(u) = 0$ or $h(u)t^2 = -1$ (division by zero)
* $Y_0(u) (1 - h(u)t^2) = 2X_0(u)t$ (would give $Y=0$).
The functions $X_0(u)$ and $Y_0(u)$ are defined in Appendix A of the paper, and depend on various properties of $E.$
The function $\psi_u$ is the same for all curves: $\psi_u(X, Y) = (x_1, x_2, x_3, z)$, where:
$$
\begin{array}{lcl}
x_1 & = & \dfrac{X}{2Y} - \dfrac{u}{2} && \\
x_2 & = & -\dfrac{X}{2Y} - \dfrac{u}{2} && \\
x_3 & = & u + 4Y^2 && \\
z & = & \dfrac{g(x_3)}{2Y}(u^2 + ux_1 + x_1^2 + a) = \dfrac{-g(u)g(x_3)}{8Y^3}
\end{array}
$$
### 2.1 Decoding for `secp256k1`
Put together and specialized for $a=0$ curves, decoding $(u, t)$ to an x-coordinate is:
**Define** $F_u(t)$ as:
* Let $X = \dfrac{u^3 + b - t^2}{2t}.$
* Let $Y = \dfrac{X + t}{u\sqrt{-3}}.$
* Return the first $x$ in $(u + 4Y^2, \dfrac{-X}{2Y} - \dfrac{u}{2}, \dfrac{X}{2Y} - \dfrac{u}{2})$ for which $g(x)$ is square.
To make sure that every input decodes to a valid x-coordinate, we remap the inputs in case
$P_u$ is not defined (when $u=0$, $t=0$, or $g(u) = -t^2$):
**Define** $F_u(t)$ as:
* Let $u'=u$ if $u \neq 0$; $1$ otherwise (guaranteeing $u' \neq 0$).
* Let $t'=t$ if $t \neq 0$; $1$ otherwise (guaranteeing $t' \neq 0$).
* Let $t''=t'$ if $g(u') \neq -t'^2$; $2t'$ otherwise (guaranteeing $t'' \neq 0$ and $g(u') \neq -t''^2$).
* Let $X = \dfrac{u'^3 + b - t''^2}{2t''}.$
* Let $Y = \dfrac{X + t''}{u'\sqrt{-3}}.$
* Return the first $x$ in $(u' + 4Y^2, \dfrac{-X}{2Y} - \dfrac{u'}{2}, \dfrac{X}{2Y} - \dfrac{u'}{2})$ for which $x^3 + b$ is square.
The choices here are not strictly necessary. Just returning a fixed constant in any of the undefined cases would suffice,
but the approach here is simple enough and gives fairly uniform output even in these cases.
**Note**: in the paper these conditions result in $\infty$ as output, due to the use of projective coordinates there.
We wish to avoid the need for callers to deal with this special case.
This is implemented in `secp256k1_ellswift_xswiftec_frac_var` (which decodes to an x-coordinate represented as a fraction), and
in `secp256k1_ellswift_xswiftec_var` (which outputs the actual x-coordinate).
## 3. The encoding function
To implement $F_u^{-1}(x)$, the function to find the set of inverses $t$ for which $F_u(t) = x$, we have to reverse the process:
* Find all the $(X, Y) \in S_u$ that could have given rise to $x$, through the $x_1$, $x_2$, or $x_3$ formulas in $\psi_u.$
* Map those $(X, Y)$ solutions to $t$ values using $P_u^{-1}(X, Y).$
* For each of the found $t$ values, verify that $F_u(t) = x.$
* Return the remaining $t$ values.
The function $P_u^{-1}$, which finds $t$ given $(X, Y) \in S_u$, is significantly simpler than $P_u:$
$$
P_u^{-1}(X, Y) = \left\\{\begin{array}{ll}
Yu\sqrt{-3} - X & a = 0 \\
\dfrac{Y-Y_0(u)}{X-X_0(u)} & a \neq 0 \land X \neq X_0(u) \\
\dfrac{-X_0(u)}{h(u)Y_0(u)} & a \neq 0 \land X = X_0(u) \land Y = Y_0(u)
\end{array}\right.
$$
The third step above, verifying that $F_u(t) = x$, is necessary because for the $(X, Y)$ values found through the $x_1$ and $x_2$ expressions,
it is possible that decoding through $\psi_u(X, Y)$ yields a valid $x_3$ on the curve, which would take precedence over the
$x_1$ or $x_2$ decoding. These $(X, Y)$ solutions must be rejected.
Since we know that exactly one or exactly three out of $\\{x_1, x_2, x_3\\}$ are valid x-coordinates for any $t$,
the case where either $x_1$ or $x_2$ is valid and in addition also $x_3$ is valid must mean that all three are valid.
This means that instead of checking whether $x_3$ is on the curve, it is also possible to check whether the other one out of
$x_1$ and $x_2$ is on the curve. This is significantly simpler, as it turns out.
Observe that $\psi_u$ guarantees that $x_1 + x_2 = -u.$ So given either $x = x_1$ or $x = x_2$, the other one of the two can be computed as
$-u - x.$ Thus, when encoding $x$ through the $x_1$ or $x_2$ expressions, one can simply check whether $g(-u-x)$ is a square,
and if so, not include the corresponding $t$ values in the returned set. As this does not need $X$, $Y$, or $t$, this condition can be determined
before those values are computed.
It is not possible that an encoding found through the $x_1$ expression decodes to a different valid x-coordinate using $x_2$ (which would
take precedence), for the same reason: if both $x_1$ and $x_2$ decodings were valid, $x_3$ would be valid as well, and thus take
precedence over both. Because of this, the $g(-u-x)$ being square test for $x_1$ and $x_2$ is the only test necessary to guarantee the found $t$
values round-trip back to the input $x$ correctly. This is the reason for choosing the $(x_3, x_2, x_1)$ precedence order in the decoder;
any order which does not place $x_3$ first requires more complicated round-trip checks in the encoder.
### 3.1 Switching to *v, w* coordinates
Before working out the formulas for all this, we switch to different variables for $S_u.$ Let $v = (X/Y - u)/2$, and
$w = 2Y.$ Or in the other direction, $X = w(u/2 + v)$ and $Y = w/2:$
* $S_u'$ becomes the set of $(v, w)$ for which $w^2 (u^2 + uv + v^2 + a) = -g(u)$ and $w \neq 0.$
* For $a=0$ curves, $P_u^{-1}$ can be stated for $(v,w)$ as $P_u^{'-1}(v, w) = w\left(\frac{\sqrt{-3}-1}{2}u - v\right).$
* $\psi_u$ can be stated for $(v, w)$ as $\psi_u'(v, w) = (x_1, x_2, x_3, z)$, where
$$
\begin{array}{lcl}
x_1 & = & v \\
x_2 & = & -u - v \\
x_3 & = & u + w^2 \\
z & = & \dfrac{g(x_3)}{w}(u^2 + uv + v^2 + a) = \dfrac{-g(u)g(x_3)}{w^3}
\end{array}
$$
We can now write the expressions for finding $(v, w)$ given $x$ explicitly, by solving each of the $\\{x_1, x_2, x_3\\}$
expressions for $v$ or $w$, and using the $S_u'$ equation to find the other variable:
* Assuming $x = x_1$, we find $v = x$ and $w = \pm\sqrt{-g(u)/(u^2 + uv + v^2 + a)}$ (two solutions).
* Assuming $x = x_2$, we find $v = -u-x$ and $w = \pm\sqrt{-g(u)/(u^2 + uv + v^2 + a)}$ (two solutions).
* Assuming $x = x_3$, we find $w = \pm\sqrt{x-u}$ and $v = -u/2 \pm \sqrt{-w^2(4g(u) + w^2h(u))}/(2w^2)$ (four solutions).
### 3.2 Avoiding computing all inverses
The *ElligatorSwift* algorithm as stated in Section 1 requires the computation of $L = F_u^{-1}(x)$ (the
set of all $t$ such that $(u, t)$ decode to $x$) in full. This is unnecessary.
Observe that the procedure of restarting with probability $(1 - \frac{\\#L}{8})$ and otherwise returning a
uniformly random element from $L$ is actually equivalent to always padding $L$ with $\bot$ values up to length 8,
picking a uniformly random element from that, restarting whenever $\bot$ is picked:
**Define** *ElligatorSwift(x)* as:
* Loop:
* Pick a uniformly random field element $u.$
* Compute the set $L = F_u^{-1}(x).$
* Let $T$ be the 8-element vector consisting of the elements of $L$, plus $8 - \\#L$ times $\\{\bot\\}.$
* Select a uniformly random $t \in T.$
* If $t \neq \bot$, return $(u, t)$; restart loop otherwise.
Now notice that the order of elements in $T$ does not matter, as all we do is pick a uniformly
random element in it, so we do not need to have all $\bot$ values at the end.
As we have 8 distinct formulas for finding $(v, w)$ (taking the variants due to $\pm$ into account),
we can associate every index in $T$ with exactly one of those formulas, making sure that:
* Formulas that yield no solutions (due to division by zero or non-existing square roots) or invalid solutions are made to return $\bot.$
* For the $x_1$ and $x_2$ cases, if $g(-u-x)$ is a square, $\bot$ is returned instead (the round-trip check).
* In case multiple formulas would return the same non- $\bot$ result, all but one of those must be turned into $\bot$ to avoid biasing those.
The last condition above only occurs with negligible probability for cryptographically-sized curves, but is interesting
to take into account as it allows exhaustive testing in small groups. See [Section 3.4](#34-dealing-with-special-cases)
for an analysis of all the negligible cases.
If we define $T = (G_{0,u}(x), G_{1,u}(x), \ldots, G_{7,u}(x))$, with each $G_{i,u}$ matching one of the formulas,
the loop can be simplified to only compute one of the inverses instead of all of them:
**Define** *ElligatorSwift(x)* as:
* Loop:
* Pick a uniformly random field element $u.$
* Pick a uniformly random integer $c$ in $[0,8).$
* Let $t = G_{c,u}(x).$
* If $t \neq \bot$, return $(u, t)$; restart loop otherwise.
This is implemented in `secp256k1_ellswift_xelligatorswift_var`.
### 3.3 Finding the inverse
To implement $G_{c,u}$, we map $c=0$ to the $x_1$ formula, $c=1$ to the $x_2$ formula, and $c=2$ and $c=3$ to the $x_3$ formula.
Those are then repeated as $c=4$ through $c=7$ for the other sign of $w$ (noting that in each formula, $w$ is a square root of some expression).
Ignoring the negligible cases, we get:
**Define** $G_{c,u}(x)$ as:
* If $c \in \\{0, 1, 4, 5\\}$ (for $x_1$ and $x_2$ formulas):
* If $g(-u-x)$ is square, return $\bot$ (as $x_3$ would be valid and take precedence).
* If $c \in \\{0, 4\\}$ (the $x_1$ formula) let $v = x$, otherwise let $v = -u-x$ (the $x_2$ formula)
* Let $s = -g(u)/(u^2 + uv + v^2 + a)$ (using $s = w^2$ in what follows).
* Otherwise, when $c \in \\{2, 3, 6, 7\\}$ (for $x_3$ formulas):
* Let $s = x-u.$
* Let $r = \sqrt{-s(4g(u) + sh(u))}.$
* Let $v = (r/s - u)/2$ if $c \in \\{3, 7\\}$; $(-r/s - u)/2$ otherwise.
* Let $w = \sqrt{s}.$
* Depending on $c:$
* If $c \in \\{0, 1, 2, 3\\}:$ return $P_u^{'-1}(v, w).$
* If $c \in \\{4, 5, 6, 7\\}:$ return $P_u^{'-1}(v, -w).$
Whenever a square root of a non-square is taken, $\bot$ is returned; for both square roots this happens with roughly
50% on random inputs. Similarly, when a division by 0 would occur, $\bot$ is returned as well; this will only happen
with negligible probability. A division by 0 in the first branch in fact cannot occur at all, because $u^2 + uv + v^2 + a = 0$
implies $g(-u-x) = g(x)$ which would mean the $g(-u-x)$ is square condition has triggered
and $\bot$ would have been returned already.
**Note**: In the paper, the $case$ variable corresponds roughly to the $c$ above, but only takes on 4 possible values (1 to 4).
The conditional negation of $w$ at the end is done randomly, which is equivalent, but makes testing harder. We choose to
have the $G_{c,u}$ be deterministic, and capture all choices in $c.$
Now observe that the $c \in \\{1, 5\\}$ and $c \in \\{3, 7\\}$ conditions effectively perform the same $v \rightarrow -u-v$
transformation. Furthermore, that transformation has no effect on $s$ in the first branch
as $u^2 + ux + x^2 + a = u^2 + u(-u-x) + (-u-x)^2 + a.$ Thus we can extract it out and move it down:
**Define** $G_{c,u}(x)$ as:
* If $c \in \\{0, 1, 4, 5\\}:$
* If $g(-u-x)$ is square, return $\bot.$
* Let $s = -g(u)/(u^2 + ux + x^2 + a).$
* Let $v = x.$
* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$
* Let $s = x-u.$
* Let $r = \sqrt{-s(4g(u) + sh(u))}.$
* Let $v = (r/s - u)/2.$
* Let $w = \sqrt{s}.$
* Depending on $c:$
* If $c \in \\{0, 2\\}:$ return $P_u^{'-1}(v, w).$
* If $c \in \\{1, 3\\}:$ return $P_u^{'-1}(-u-v, w).$
* If $c \in \\{4, 6\\}:$ return $P_u^{'-1}(v, -w).$
* If $c \in \\{5, 7\\}:$ return $P_u^{'-1}(-u-v, -w).$
This shows there will always be exactly 0, 4, or 8 $t$ values for a given $(u, x)$ input.
There can be 0, 1, or 2 $(v, w)$ pairs before invoking $P_u^{'-1}$, and each results in 4 distinct $t$ values.
### 3.4 Dealing with special cases
As mentioned before there are a few cases to deal with which only happen in a negligibly small subset of inputs.
For cryptographically sized fields, if only random inputs are going to be considered, it is unnecessary to deal with these. Still, for completeness
we analyse them here. They generally fall into two categories: cases in which the encoder would produce $t$ values that
do not decode back to $x$ (or at least cannot guarantee that they do), and cases in which the encoder might produce the same
$t$ value for multiple $c$ inputs (thereby biasing that encoding):
* In the branch for $x_1$ and $x_2$ (where $c \in \\{0, 1, 4, 5\\}$):
* When $g(u) = 0$, we would have $s=w=Y=0$, which is not on $S_u.$ This is only possible on even-ordered curves.
Excluding this also removes the one condition under which the simplified check for $x_3$ on the curve
fails (namely when $g(x_1)=g(x_2)=0$ but $g(x_3)$ is not square).
This does exclude some valid encodings: when both $g(u)=0$ and $u^2+ux+x^2+a=0$ (also implying $g(x)=0$),
the $S_u'$ equation degenerates to $0 = 0$, and many valid $t$ values may exist. Yet, these cannot be targeted uniformly by the
encoder anyway as there will generally be more than 8.
* When $g(x) = 0$, the same $t$ would be produced as in the $x_3$ branch (where $c \in \\{2, 3, 6, 7\\}$) which we give precedence
as it can deal with $g(u)=0$.
This is again only possible on even-ordered curves.
* In the branch for $x_3$ (where $c \in \\{2, 3, 6, 7\\}$):
* When $s=0$, a division by zero would occur.
* When $v = -u-v$ and $c \in \\{3, 7\\}$, the same $t$ would be returned as in the $c \in \\{2, 6\\}$ cases.
It is equivalent to checking whether $r=0$.
This cannot occur in the $x_1$ or $x_2$ branches, as it would trigger the $g(-u-x)$ is square condition.
A similar concern for $w = -w$ does not exist, as $w=0$ is already impossible in both branches: in the first
it requires $g(u)=0$ which is already outlawed on even-ordered curves and impossible on others; in the second it would trigger division by zero.
* Curve-specific special cases also exist that need to be rejected, because they result in $(u,t)$ which is invalid to the decoder, or because of division by zero in the encoder:
* For $a=0$ curves, when $u=0$ or when $t=0$. The latter can only be reached by the encoder when $g(u)=0$, which requires an even-ordered curve.
* For $a \neq 0$ curves, when $X_0(u)=0$, when $h(u)t^2 = -1$, or when $w(u + 2v) = 2X_0(u)$ while also either $w \neq 2Y_0(u)$ or $h(u)=0$.
**Define** a version of $G_{c,u}(x)$ which deals with all these cases:
* If $a=0$ and $u=0$, return $\bot.$
* If $a \neq 0$ and $X_0(u)=0$, return $\bot.$
* If $c \in \\{0, 1, 4, 5\\}:$
* If $g(u) = 0$ or $g(x) = 0$, return $\bot$ (even curves only).
* If $g(-u-x)$ is square, return $\bot.$
* Let $s = -g(u)/(u^2 + ux + x^2 + a)$ (cannot cause division by zero).
* Let $v = x.$
* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$
* Let $s = x-u.$
* Let $r = \sqrt{-s(4g(u) + sh(u))}$; return $\bot$ if not square.
* If $c \in \\{3, 7\\}$ and $r=0$, return $\bot.$
* If $s = 0$, return $\bot.$
* Let $v = (r/s - u)/2.$
* Let $w = \sqrt{s}$; return $\bot$ if not square.
* If $a \neq 0$ and $w(u+2v) = 2X_0(u)$ and either $w \neq 2Y_0(u)$ or $h(u) = 0$, return $\bot.$
* Depending on $c:$
* If $c \in \\{0, 2\\}$, let $t = P_u^{'-1}(v, w).$
* If $c \in \\{1, 3\\}$, let $t = P_u^{'-1}(-u-v, w).$
* If $c \in \\{4, 6\\}$, let $t = P_u^{'-1}(v, -w).$
* If $c \in \\{5, 7\\}$, let $t = P_u^{'-1}(-u-v, -w).$
* If $a=0$ and $t=0$, return $\bot$ (even curves only).
* If $a \neq 0$ and $h(u)t^2 = -1$, return $\bot.$
* Return $t.$
Given any $u$, using this algorithm over all $x$ and $c$ values, every $t$ value will be reached exactly once,
for an $x$ for which $F_u(t) = x$ holds, except for these cases that will not be reached:
* All cases where $P_u(t)$ is not defined:
* For $a=0$ curves, when $u=0$, $t=0$, or $g(u) = -t^2.$
* For $a \neq 0$ curves, when $h(u)t^2 = -1$, $X_0(u) = 0$, or $Y_0(u) (1 - h(u) t^2) = 2X_0(u)t.$
* When $g(u)=0$, the potentially many $t$ values that decode to an $x$ satisfying $g(x)=0$ using the $x_2$ formula. These were excluded by the $g(u)=0$ condition in the $c \in \\{0, 1, 4, 5\\}$ branch.
These cases form a negligible subset of all $(u, t)$ for cryptographically sized curves.
### 3.5 Encoding for `secp256k1`
Specialized for odd-ordered $a=0$ curves:
**Define** $G_{c,u}(x)$ as:
* If $u=0$, return $\bot.$
* If $c \in \\{0, 1, 4, 5\\}:$
* If $(-u-x)^3 + b$ is square, return $\bot$
* Let $s = -(u^3 + b)/(u^2 + ux + x^2)$ (cannot cause division by 0).
* Let $v = x.$
* Otherwise, when $c \in \\{2, 3, 6, 7\\}:$
* Let $s = x-u.$
* Let $r = \sqrt{-s(4(u^3 + b) + 3su^2)}$; return $\bot$ if not square.
* If $c \in \\{3, 7\\}$ and $r=0$, return $\bot.$
* If $s = 0$, return $\bot.$
* Let $v = (r/s - u)/2.$
* Let $w = \sqrt{s}$; return $\bot$ if not square.
* Depending on $c:$
* If $c \in \\{0, 2\\}:$ return $w(\frac{\sqrt{-3}-1}{2}u - v).$
* If $c \in \\{1, 3\\}:$ return $w(\frac{\sqrt{-3}+1}{2}u + v).$
* If $c \in \\{4, 6\\}:$ return $w(\frac{-\sqrt{-3}+1}{2}u + v).$
* If $c \in \\{5, 7\\}:$ return $w(\frac{-\sqrt{-3}-1}{2}u - v).$
This is implemented in `secp256k1_ellswift_xswiftec_inv_var`.
And the x-only ElligatorSwift encoding algorithm is still:
**Define** *ElligatorSwift(x)* as:
* Loop:
* Pick a uniformly random field element $u.$
* Pick a uniformly random integer $c$ in $[0,8).$
* Let $t = G_{c,u}(x).$
* If $t \neq \bot$, return $(u, t)$; restart loop otherwise.
Note that this logic does not take the remapped $u=0$, $t=0$, and $g(u) = -t^2$ cases into account; it just avoids them.
While it is not impossible to make the encoder target them, this would increase the maximum number of $t$ values for a given $(u, x)$
combination beyond 8, and thereby slow down the ElligatorSwift loop proportionally, for a negligible gain in uniformity.
## 4. Encoding and decoding full *(x, y)* coordinates
So far we have only addressed encoding and decoding x-coordinates, but in some cases an encoding
for full points with $(x, y)$ coordinates is desirable. It is possible to encode this information
in $t$ as well.
Note that for any $(X, Y) \in S_u$, $(\pm X, \pm Y)$ are all on $S_u.$ Moreover, all of these are
mapped to the same x-coordinate. Negating $X$ or negating $Y$ just results in $x_1$ and $x_2$
being swapped, and does not affect $x_3.$ This will not change the outcome x-coordinate as the order
of $x_1$ and $x_2$ only matters if both were to be valid, and in that case $x_3$ would be used instead.
Still, these four $(X, Y)$ combinations all correspond to distinct $t$ values, so we can encode
the sign of the y-coordinate in the sign of $X$ or the sign of $Y.$ They correspond to the
four distinct $P_u^{'-1}$ calls in the definition of $G_{u,c}.$
**Note**: In the paper, the sign of the y coordinate is encoded in a separately-coded bit.
To encode the sign of $y$ in the sign of $Y:$
**Define** *Decode(u, t)* for full $(x, y)$ as:
* Let $(X, Y) = P_u(t).$
* Let $x$ be the first value in $(u + 4Y^2, \frac{-X}{2Y} - \frac{u}{2}, \frac{X}{2Y} - \frac{u}{2})$ for which $g(x)$ is square.
* Let $y = \sqrt{g(x)}.$
* If $sign(y) = sign(Y)$, return $(x, y)$; otherwise return $(x, -y).$
And encoding would be done using a $G_{c,u}(x, y)$ function defined as:
**Define** $G_{c,u}(x, y)$ as:
* If $c \in \\{0, 1\\}:$
* If $g(u) = 0$ or $g(x) = 0$, return $\bot$ (even curves only).
* If $g(-u-x)$ is square, return $\bot.$
* Let $s = -g(u)/(u^2 + ux + x^2 + a)$ (cannot cause division by zero).
* Let $v = x.$
* Otherwise, when $c \in \\{2, 3\\}:$
* Let $s = x-u.$
* Let $r = \sqrt{-s(4g(u) + sh(u))}$; return $\bot$ if not square.
* If $c = 3$ and $r = 0$, return $\bot.$
* Let $v = (r/s - u)/2.$
* Let $w = \sqrt{s}$; return $\bot$ if not square.
* Let $w' = w$ if $sign(w/2) = sign(y)$; $-w$ otherwise.
* Depending on $c:$
* If $c \in \\{0, 2\\}:$ return $P_u^{'-1}(v, w').$
* If $c \in \\{1, 3\\}:$ return $P_u^{'-1}(-u-v, w').$
Note that $c$ now only ranges $[0,4)$, as the sign of $w'$ is decided based on that of $y$, rather than on $c.$
This change makes some valid encodings unreachable: when $y = 0$ and $sign(Y) \neq sign(0)$.
In the above logic, $sign$ can be implemented in several ways, such as parity of the integer representation
of the input field element (for prime-sized fields) or the quadratic residuosity (for fields where
$-1$ is not square). The choice does not matter, as long as it only takes on two possible values, and for $x \neq 0$ it holds that $sign(x) \neq sign(-x)$.
### 4.1 Full *(x, y)* coordinates for `secp256k1`
For $a=0$ curves, there is another option. Note that for those,
the $P_u(t)$ function translates negations of $t$ to negations of (both) $X$ and $Y.$ Thus, we can use $sign(t)$ to
encode the y-coordinate directly. Combined with the earlier remapping to guarantee all inputs land on the curve, we get
as decoder:
**Define** *Decode(u, t)* as:
* Let $u'=u$ if $u \neq 0$; $1$ otherwise.
* Let $t'=t$ if $t \neq 0$; $1$ otherwise.
* Let $t''=t'$ if $u'^3 + b + t'^2 \neq 0$; $2t'$ otherwise.
* Let $X = \dfrac{u'^3 + b - t''^2}{2t''}.$
* Let $Y = \dfrac{X + t''}{u'\sqrt{-3}}.$
* Let $x$ be the first element of $(u' + 4Y^2, \frac{-X}{2Y} - \frac{u'}{2}, \frac{X}{2Y} - \frac{u'}{2})$ for which $g(x)$ is square.
* Let $y = \sqrt{g(x)}.$
* Return $(x, y)$ if $sign(y) = sign(t)$; $(x, -y)$ otherwise.
This is implemented in `secp256k1_ellswift_swiftec_var`. The used $sign(x)$ function is the parity of $x$ when represented as in integer in $[0,q).$
The corresponding encoder would invoke the x-only one, but negating the output $t$ if $sign(t) \neq sign(y).$
This is implemented in `secp256k1_ellswift_elligatorswift_var`.
Note that this is only intended for encoding points where both the x-coordinate and y-coordinate are unpredictable. When encoding x-only points
where the y-coordinate is implicitly even (or implicitly square, or implicitly in $[0,q/2]$), the encoder in
[Section 3.5](#35-encoding-for-secp256k1) must be used, or a bias is reintroduced that undoes all the benefit of using ElligatorSwift
in the first place.

Notes on the musig module API
===========================
The following sections contain additional notes on the API of the musig module (`include/secp256k1_musig.h`).
A usage example can be found in `examples/musig.c`.
## API misuse
The musig API is designed with a focus on misuse resistance.
However, due to the interactive nature of the MuSig protocol, there are additional failure modes that are not present in regular (single-party) Schnorr signature creation.
While the results can be catastrophic (e.g. leaking of the secret key), it is unfortunately not possible for the musig implementation to prevent all such failure modes.
Therefore, users of the musig module must take great care to make sure of the following:
1. A unique nonce per signing session is generated in `secp256k1_musig_nonce_gen`.
See the corresponding comment in `include/secp256k1_musig.h` for how to ensure that.
2. The `secp256k1_musig_secnonce` structure is never copied or serialized.
See also the comment on `secp256k1_musig_secnonce` in `include/secp256k1_musig.h`.
3. Opaque data structures are never written to or read from directly.
Instead, only the provided accessor functions are used.
## Key Aggregation and (Taproot) Tweaking
Given a set of public keys, the aggregate public key is computed with `secp256k1_musig_pubkey_agg`.
A plain tweak can be added to the resulting public key with `secp256k1_ec_pubkey_tweak_add` by setting the `tweak32` argument to the hash defined in BIP 32. Similarly, a Taproot tweak can be added with `secp256k1_xonly_pubkey_tweak_add` by setting the `tweak32` argument to the TapTweak hash defined in BIP 341.
Both types of tweaking can be combined and invoked multiple times if the specific application requires it.
## Signing
This is covered by `examples/musig.c`.
Essentially, the protocol proceeds in the following steps:
1. Generate a keypair with `secp256k1_keypair_create` and obtain the public key with `secp256k1_keypair_pub`.
2. Call `secp256k1_musig_pubkey_agg` with the pubkeys of all participants.
3. Optionally add a (Taproot) tweak with `secp256k1_musig_pubkey_xonly_tweak_add` and a plain tweak with `secp256k1_musig_pubkey_ec_tweak_add`.
4. Generate a pair of secret and public nonce with `secp256k1_musig_nonce_gen` and send the public nonce to the other signers.
5. Someone (not necessarily the signer) aggregates the public nonces with `secp256k1_musig_nonce_agg` and sends it to the signers.
6. Process the aggregate nonce with `secp256k1_musig_nonce_process`.
7. Create a partial signature with `secp256k1_musig_partial_sign`.
8. Verify the partial signatures (optional in some scenarios) with `secp256k1_musig_partial_sig_verify`.
9. Someone (not necessarily the signer) obtains all partial signatures and aggregates them into the final Schnorr signature using `secp256k1_musig_partial_sig_agg`.
The aggregate signature can be verified with `secp256k1_schnorrsig_verify`.
Steps 1 through 5 above can occur before or after the signers are aware of the message to be signed.
Whenever possible, it is recommended to generate the nonces only after the message is known.
This provides enhanced defense-in-depth measures, protecting against potential API misuse in certain scenarios.
However, it does require two rounds of communication during the signing process.
The alternative, generating the nonces in a pre-processing step before the message is known, eliminates these additional protective measures but allows for non-interactive signing.
Similarly, the API supports an alternative protocol flow where generating the aggregate key (steps 1 to 3) is allowed to happen after exchanging nonces (steps 4 to 5).
## Verification
A participant who wants to verify the partial signatures, but does not sign itself may do so using the above instructions except that the verifier skips steps 1, 4 and 7.
