Chacha20Poly1305

Project description

Simple pure-python chacha20-poly1305 implementation based on tlslite-ng code. Designed to be compatible with Cryptography API.

import os
from chacha20poly1305 import ChaCha20Poly1305

key = os.urandom(32)
cip = ChaCha20Poly1305(key)

nonce = os.urandom(12)
ciphertext = cip.encrypt(nonce, b'test')

plaintext = cip.decrypt(nonce, ciphertext)
print(plaintext)

Pip

pip install chacha20poly1305

Note

Please note the pure python implementation probably suffers form side-channels leakage (timing, memory access). For constant time implementations use compiled versions:
