Module solana_libra_nextgen_crypto::ed25519

This module provides an API for the PureEdDSA signature scheme over the ed25519 twisted Edwards curve as defined in RFC8032.

Signature verification also checks and rejects non-canonical signatures.

Examples

use crypto::hash::{CryptoHasher, TestOnlyHasher};
use nextgen_crypto::{
    ed25519::*,
    traits::{Signature, SigningKey, Uniform},
};
use rand::{rngs::StdRng, SeedableRng};

let mut hasher = TestOnlyHasher::default();
hasher.write("Test message".as_bytes());
let hashed_message = hasher.finish();

let mut rng: StdRng = SeedableRng::from_seed([0; 32]);
let private_key = Ed25519PrivateKey::generate_for_testing(&mut rng);
let public_key: Ed25519PublicKey = (&private_key).into();
let signature = private_key.sign_message(&hashed_message);
assert!(signature.verify(&hashed_message, &public_key).is_ok());

Note: The above example generates a private key using a private function intended only for testing purposes. Production code should find an alternate means for secure key generation.
