Python wrapper around implementation of the Classic McEliece cryptosystem.

To access the Python functions provided by mceliece, import the library (for, e.g., mceliece6960119):

from mceliece import mceliece6960119

To generate a key pair:

pk,sk = mceliece6960119.keypair()

To generate a ciphertext c encapsulating a randomly generated session key k:

c,k = mceliece6960119.enc(pk)

To recover a session key from a ciphertext:

k = mceliece6960119.dec(c,sk)

As a larger example, the following test script creates a key pair, creates a ciphertext and session key, and then recovers the session key from the ciphertext:

import mceliece
kem = mceliece.mceliece6960119
pk,sk = kem.keypair()
c,k = kem.enc(pk)
assert k == kem.dec(c,sk)
