5.3 `pisces.cryptrand` - Interface to cryptographic random number generators

This module provides a common interface to the various cryptographic random numbers that may be available on a particular system. The module defines one function random and one constant implementation, which is a string that describes the implementation used for random.

random (num): Return num bytes of random data.

The implementation depends on the random number generators available on a particular system. On Linux systems, /dev/random is used. This module can also use the Yarrow daemon provided with Pisces or the Entropy Gathering Daemon from gpg if it is installed in ' /.gnupg/entropy.

WARNING: If no cryptographic random number generator is available, Python's whrandom implementation will be used. The is not a cryptographic random number generator.
