Module rust_sike::pke

Public-key cryptosystem:

A Message is encrypted using the public key, and decrypted using the corresponding private key.

Examples

use rust_sike::{self, pke::{PKE, Message}};
let params = rust_sike::sike_p434_params(
    Some(rust_sike::P434_TWO_TORSION_STRATEGY.to_vec()),
    Some(rust_sike::P434_THREE_TORSION_STRATEGY.to_vec()),
);

let pke = PKE::setup(params.clone());

// Alice generates a keypair, she publishes her pk
let (sk, pk) = pke.gen();

// Bob writes a message
let msg = Message::from_bytes(vec![0; params.secparam / 8]);
// Bob encrypts the message using Alice's pk
let ciphertext = pke.enc(&pk, msg.clone());

// Bob sends the ciphertext to Alice
// Alice decrypts the message using her sk
let msg_recovered = pke.dec(&sk, ciphertext);

// Alice should correctly recover Bob's plaintext message
assert_eq!(msg_recovered.to_bytes(), msg.to_bytes());
