            Chacha20poly1305
================

Simple pure-python chacha20-poly1305 implementation based on
`tlslite-ng <https://github.com/tomato42/tlslite-ng>`__ code. Designed
to be compatible with Cryptography API.

.. code:: python

    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
---

.. code:: bash

    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:
