Python wrapper around implementation of the Streamlined NTRU Prime cryptosystems

Python wrapper around implementation of the Streamlined NTRU Prime cryptosystem.

To access the Python functions provided by ntruprime, import the library (for, e.g., sntrup1277):

from ntruprime import sntrup1277

To generate a key pair:

pk,sk = sntrup1277.keypair()

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

c,k = sntrup1277.enc(pk)

To recover a session key from a ciphertext:

k = sntrup1277.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 ntruprime
kem = ntruprime.sntrup1277
pk,sk = kem.keypair()
c,k = kem.enc(pk)
assert k == kem.dec(c,sk)
