Module ed25519 

This module contains an implementation of the Ed25519 signature scheme.

Messages can be signed and the signature can be verified again:

use rand::thread_rng;
let kp = Ed25519KeyPair::generate(&mut thread_rng());
let message: &[u8] = b"Hello, world!";
let signature = kp.sign(message);
assert!(kp.public().verify(message, &signature).is_ok());

Structs

Ed25519AggregateSignature

Aggregation of multiple Ed25519 signatures.

Ed25519KeyPair

Ed25519 key pair.

Ed25519PrivateKey

Ed25519 private key.

Ed25519PublicKey

Ed25519 public key.

Ed25519Signature

Ed25519 signature.

SingleSignature

Constants

ED25519_KEYPAIR_LENGTH

The key pair bytes length is the same as the private key length. This enforces deserialization to always derive the public key from the private key.

ED25519_PRIVATE_KEY_LENGTH

The length of a private key in bytes.

ED25519_PUBLIC_KEY_LENGTH

The length of a public key in bytes.

ED25519_SIGNATURE_LENGTH

The length of a signature in bytes.
