Detailed Description
KeccakGoodRng - A KeccakF1600 based good quality pseudo-random number generator. This class provides very good random numbers, using the KeccakF1600 algorithm without the extra security margins applied for SHA3 hash generation. This improves performance significantly without noticably trading random number quality. For cryptography grade number generation KeccakCryptoRng should be used instead.
