Introduction
============

pyrad is an implementation of a RADIUS client/server as described in RFC2865.
It takes care of all the details like building RADIUS packets, sending
them and decoding responses.

Here is an example of doing a authentication request:

.. code-block:: python

    from pyrad.client import Client
    from pyrad.dictionary import Dictionary
    import pyrad.packet

    srv = Client(
        server="localhost",
        secret=b"Kah3choteereethiejeimaeziecumi",
        dict=Dictionary("dictionary"),
    )

    # create request
    req = srv.CreateAuthPacket(
        code=pyrad.packet.AccessRequest, User_Name="wichert", NAS_Identifier="localhost"
    )
    req["User-Password"] = req.PwCrypt("password")

    # send request
    reply = srv.SendPacket(req)

    if reply.code == pyrad.packet.AccessAccept:
        print("access accepted")
    else:
        print("access denied")

    print("Attributes returned by server:")
    for key, val in reply.items():
        print(f"{key}: {val}")


Requirements & Installation
===========================

pyrad requires Python 3.8 or later

Installing is simple; pyrad uses the standard distutils system for installing
Python modules::

  python setup.py install
