Python wrapper around implementation of the Classic Mceliece cryptosystems

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)
