Crate kyber_kem

Implementation of the Kyber IND-CCA2 secure key encapsulation mechanism (KEM)

Example usage:

use rand::rngs::OsRng;
use kyber_kem::{kem_keypair_1024, kem_encrypt_1024, kem_decrypt_1024};

let (secret_key, public_key) = kem_keypair_1024(&mut OsRng);
let (ciphertext, shared_secret) = kem_encrypt_1024(public_key, &mut OsRng);
let dec_shared_secret = kem_decrypt_1024(ciphertext, secret_key);
assert_eq!(shared_secret, dec_shared_secret);
