vrf-r255

This crate provides an RFC 9381 Verifiable Random Function (VRF), which is the public key version of a keyed cryptographic hash. Only the holder of the secret key can compute the hash, but anyone with the public key can verify the correctness of the hash.

vrf-r255 is built on the ristretto255 group specified in RFC 9496. More specifically, it is an implementation of the ECVRF-RISTRETTO255-SHA512 ciphersuite of the RFC 9381 ECVRF construction.
