XRP Ledger escrows require PREIMAGE-SHA-256 [Crypto-Conditions](https://tools.ietf.org/html/draft-thomas-crypto-conditions-03). To calculate a condition and fulfillment in the proper format, you should use a Crypto-Conditions library such as [five-bells-condition](https://github.com/interledgerjs/five-bells-condition). For fulfillments, Ripple recommends using one of the following methods to generate the fulfillment:
- Use a cryptographically secure source of randomness to generate at least 32 random bytes.
- Follow Interledger Protocol's [PSK specification](https://github.com/interledger/rfcs/blob/master/0016-pre-shared-key/0016-pre-shared-key.md) and use an HMAC-SHA-256 of the ILP packet as the fulfillment.
- Follow Interledger Protocol's [PSK specification](https://github.com/interledger/rfcs/blob/master/deprecated/0016-pre-shared-key/0016-pre-shared-key.md) and use an HMAC-SHA-256 of the ILP packet as the fulfillment.
Example JavaScript code for a random fulfillment and condition:
