Module cryptoxide::ed25519

Expand description

ED25519 Signature Scheme

Examples

Creating a signature, and verifying the signature:

use cryptoxide::ed25519;

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

The signature is 64 bytes composed of R || S where R is 32 bytes and S is 32 bytes also.
