eciesrs

Elliptic Curve Integrated Encryption Scheme for secp256k1 in Rust, based on pure Rust implementation of secp256k1.

This is the Rust version of eciespy.

API

pub fn encrypt(receiver_pub: &[u8], msg: &[u8]) -> Result<Vec<u8>, SecpError>

pub fn decrypt(receiver_sec: &[u8], msg: &[u8]) -> Result<Vec<u8>, SecpError>

Quick Start

const MSG: &str = "helloworld";
let (sk, pk) = generate_keypair();
let (sk, pk) = (&sk.serialize(), &pk.serialize());

let msg = MSG.as_bytes();
assert_eq!(
    msg,
    decrypt(sk, &encrypt(pk, msg).unwrap()).unwrap().as_slice()
);
