Baby Kyber

This is a scaled down implementation of NIST Finalist Post Quantum Cryptography algorithm, KYBER.

To generate public and private keys:

kb = BabyKyber(KYBER_Q, n, k)
public_key, private_key = kb.keygen()

To encrypt a message, which must be a bytes object:

cipher_u, cipher_v = kb.encrypt(message, public_key)

To decrypt encrypted message:

message = kb.decrypt(cipher_u, cipher_v, private_key)
