Class Nettle.Fortuna

Description

Implements the Fortuna PRNG generator, designed by Niels Ferguson and Bruce Schneier and described in Practical Cryptography. Web published exerpt at https://www.schneier.com:443/fortuna.pdf

This implementation uses AES256 to generate output and SHA256 to generate keys.

To use this class an entropy accumulator needs to be implemented and supply the reseed() method with new entopy.
