Module secp256r1

Secp256r1 implementation of the Scheme trait.

This implementation operates over public keys in compressed form (SEC 1, Version 2.0, Section 2.3.3), generates deterministic signatures as specified in RFC 6979, and enforces signatures are normalized according to BIP 62.

Example

use commonware_cryptography::{secp256r1, PrivateKey, PublicKey, Signature, PrivateKeyExt as _, Verifier as _, Signer as _};
use rand::rngs::OsRng;

// Generate a new private key
let mut signer = secp256r1::PrivateKey::from_rng(&mut OsRng);

// Create a message to sign
let namespace = Some(&b"demo"[..]);
let msg = b"hello, world!";

// Sign the message
let signature = signer.sign(namespace, msg);

// Verify the signature
assert!(signer.public_key().verify(namespace, msg, &signature));
