An implementation of Schnorr signatures on the Ristretto group for both single and threshold numbers of signers (FROST).
Examples
Creating a Signature
with a single signer, serializing and deserializing it, and verifying the
signature:
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_bytes`/`to_bytes`
let sig_bytes = sig.to_bytes();
let pk_bytes = VerifyingKey::from(&sk).to_bytes();
// Deserialize and verify the signature.
let sig = Signature::from_bytes(sig_bytes)?;
assert!(
VerifyingKey::from_bytes(pk_bytes)
.and_then(|pk| pk.verify(msg, &sig))
.is_ok()
);
# Ok::<(), Error>(())
