README.md
An implementation of Schnorr sigantures on the Ristretto group for both single and threshold numbers of signers (FROST).
In addition to the Signature
, SigningKey
, VerificationKey
types, the library also provides
VerificationKeyBytes
, a refinement of a [u8; 32]
indicating that bytes represent an encoding
of averification key. This allows the VerificationKey
type to cache verification checks related to
the verification key encoding.
Examples
Creating a Signature
with a single signer, serializing and deserializing it, and verifying the
signature:
# use std::convert::TryFrom;
use rand::thread_rng;
use frost_ristretto255::*;
let msg = b"Hello!";
// Generate a secret key and sign the message
let sk = SigningKey::new(thread_rng());
let sig = sk.sign(thread_rng(), msg);
// Types can be converted to raw byte arrays using From/Into
let sig_bytes: [u8; 64] = sig.into();
let pk_bytes: [u8; 32] = VerificationKey::from(&sk).into();
// Deserialize and verify the signature.
let sig: Signature = sig_bytes.into();
assert!(
VerificationKey::try_from(pk_bytes)
.and_then(|pk| pk.verify(msg, &sig))
.is_ok()
);
