-## Renaming ripple(d) to xrpl(d)
-
-In the initial phases of development of the XRPL, the open source codebase was
-called "rippled" and it remains with that name even today. Today, over 1000
-nodes run the application, and code contributions have been submitted by
-developers located around the world. The XRPL community is larger than ever.
-In light of the decentralized and diversified nature of XRPL, we will rename any
-references to `ripple` and `rippled` to `xrpl` and `xrpld`, when appropriate.
-
-See [here](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html) for
-more information.
-
-### Scripts
-
-To facilitate this transition, there will be multiple scripts that developers
-can run on their own PRs and forks to minimize conflicts. Each script should be
-run from the repository root.
-
-1. `.github/scripts/rename/definitions.sh`: This script will rename all
-   definitions, such as include guards, from `RIPPLE_XXX` and `RIPPLED_XXX` to
-   `XRPL_XXX`.
-2. `.github/scripts/rename/copyright.sh`: This script will remove superflous
-   copyright notices.
-3. `.github/scripts/rename/cmake.sh`: This script will rename all CMake files
-   from `RippleXXX.cmake` or `RippledXXX.cmake` to `XrplXXX.cmake`, and any
-   references to `ripple` and `rippled` (with or without capital letters) to
-   `xrpl` and `xrpld`, respectively. The name of the binary will remain as-is,
-   and will only be renamed to `xrpld` by a later script.
-4. `.github/scripts/rename/binary.sh`: This script will rename the binary from
-   `rippled` to `xrpld`, and reverses the symlink so that `rippled` points to
-   the `xrpld` binary.
-5. `.github/scripts/rename/namespace.sh`: This script will rename the C++
-   namespaces from `ripple` to `xrpl`.
-6. `.github/scripts/rename/config.sh`: This script will rename the config from
-   `rippled.cfg` to `xrpld.cfg`, and updating the code accordingly. The old
-   filename will still be accepted.
-
-You can run all these scripts from the repository root as follows:
-
-```shell
-./.github/scripts/rename/definitions.sh .
-./.github/scripts/rename/copyright.sh .
-./.github/scripts/rename/cmake.sh .
-./.github/scripts/rename/binary.sh .
-./.github/scripts/rename/namespace.sh .
-./.github/scripts/rename/config.sh .

-# Conan lockfile
-
-To achieve reproducible dependencies, we use a [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, so 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.
-
-To update a lockfile, run from the repository root: `./conan/lockfile/regenerate.sh`

+
+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.

+
+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]

+    ................................ [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.
