Module cryptoxide::ed25519

ED25519 Signature Scheme

Examples

Creating a signature, and verifying the signature:

use cryptoxide::ed25519;

let message = "messages".as_bytes();
let seed = [0u8;32]; // seed only for example !
let (secret, public) = ed25519::keypair(&seed[..]);
let signature = ed25519::signature(message, &secret[..]);
let verified = ed25519::verify(message, &public[..], &signature[..]);
assert!(verified);
