Module ed25519 

Ed25519, a signature scheme.

Ed25519 builds a signature scheme over a curve that is isogenous to curve25519. This module provides the “pure” signature scheme described in https://datatracker.ietf.org/doc/html/rfc8032.

use bssl_crypto::ed25519;

let key = ed25519::PrivateKey::generate();
// Publish your public key.
let public_key_bytes = *key.to_public().as_bytes();

// Sign and publish some message.
let signed_message = b"hello world";
let mut sig = key.sign(signed_message);

// Anyone with the public key can verify it.
let public_key = ed25519::PublicKey::from_bytes(&public_key_bytes);
assert!(public_key.verify(signed_message, &sig).is_ok());
