This crate provides a set of cryptographic helper functions. It provide secp256k1 PublicKey, PrivateKey, signer, and hash functions. This crate is based on secp256k1 and [tiny-keccak].

Usage

elabs-crypto = "0.1"

Example

use elabs_crypto::*;

fn main() {
       let msg = b"hello world";
       let hash = keccak256(msg);
       let sk = PrivateKey::random();
       let pk = sk.to_public().unwrap();
       let sig = sign(msg, sk).unwrap();
       let (recid, bsig) = sig.serialize_compact();
       let pk2 = ecrecover(&hash, &bsig, recid.to_i32() as u8).unwrap();
       assert_eq!(pk, pk2);
}
