- siphash-4-8 keyprocedure
- siphash-4-8 key messageprocedure
siphash-2-4 and siphash-4-8 are predefined hashing procedures.
Each takes one or two SRFI-4 u8vector arguments, the key and message to hash, and returns a positive integer. key should have a length of 16, while message may be any length. If message isn't given, a prekeyed hashing function is returned.
The SipHash specification recommends SipHash-2-4 for performance and SipHash-4-8 for cryptographic security.
