simple_sign

Simple signing library.

This crate provides a small API for working with cryptographic signatures, including:

• Signature: a signature wrapper that stores the raw signature bytes plus the SigningAlgorithm used.
• SigningAlgorithm: an enum of supported algorithms (see src/signing_algorithm.rs).
• Signers: Ed25519Signer, RsaSigner, and Secp256k1Signer.

Installation

Add to your Cargo.toml:

[dependencies]
simple_sign = "0.2.0"

Usage

Basic construction and inspection:

use std::sync::Arc;

use base_xx::ByteVec;
use simple_sign::{Signature, SigningAlgorithm};

let sig = Signature::new_with_algorithm(
    SigningAlgorithm::ED25519,
    Arc::new(ByteVec::new(Arc::new(vec![0u8; 64]))),
);
assert_eq!(sig.get_algorithm(), SigningAlgorithm::ED25519);
let _bytes = sig.get_signature();

Signing a hash:

use std::sync::Arc;

use base_xx::ByteVec;
use simple_sign::{Ed25519Signer, Signer};
use slahasher::{Hash, HashAlgorithm};

let signer = Arc::new(Ed25519Signer::default());

let data = b"hello";
let bytes = Arc::new(ByteVec::new(Arc::new(data.to_vec())));
let hash = Hash::try_hash(Arc::clone(&bytes), HashAlgorithm::KECCAK512).unwrap();

let signature = signer.sign(hash).unwrap();
assert_eq!(signature.get_signature().get_bytes().len(), 64);

Serialisation helpers are implemented via base_xx’s Encodable trait (see Signature’s TryFrom implementations in src/signature.rs).
