<!-- =========== START OF MODULE DESCRIPTION =========== -->
<h2 class="module">Module openid.cryptutil</h2>
<p>Module containing a cryptographic-quality source of randomness and
other cryptographically useful functionality</p>
<p>Python 2.4 needs no external support for this module, nor does Python
2.3 on a system with /dev/urandom.</p>
<p>Other configurations will need a quality source of random bytes and
access to a function that will convert binary strings to long integers.
This module will work with the Python Cryptography Toolkit (pycrypto) if
it is present. pycrypto can be found with a search engine, but is
currently found at:</p>
