pure-sasl is a pure python client-side SASL implementation.

At the moment, it supports the following mechanisms: ANONYMOUS, PLAIN, EXTERNAL,

CRAM-MD5, DIGEST-MD5, and GSSAPI. Support for other mechanisms may be added in the

future. Only GSSAPI supports a QOP higher than auth. Always use TLS!

Both Python 2 and Python 3 are supported.

Example Usage

-------------

.. code-block:: python

    from puresasl.client import SASLClient

    sasl = SASLClient('somehost2', 'customprotocol')

    conn = get_connection_to('somehost2')

    available_mechs = conn.get_mechanisms()

    sasl.choose_mechanism(available_mechs, allow_anonymous=False)

    while True:

        status, challenge = conn.get_challenge()

        if status == 'COMPLETE':

            break

        elif status == 'OK':

            response = sasl.process(challenge)

            conn.send_response(response)

        else:

            raise Exception(status)

    if not sasl.complete:

        raise Exception("SASL negotiation did not complete")

    # begin normal communication

    encoded = conn.fetch_data()

    decoded = sasl.unwrap(encoded)

    response = process_data(decoded)

    conn.send_data(sasl.wrap(response))
