Functions

addEntropy void addEntropy(const(ubyte)* input, size_t length): Add entropy to this RNG.
clear void clear(): Clear all internally held values of this RNG.
isSeeded bool isSeeded(): Check whether this RNG is seeded.
nextByte ubyte nextByte(): Return a random ubyte
randomVec SecureVector!ubyte randomVec(size_t bytes): Return a random vector
randomize void randomize(ubyte* output, size_t length): Randomize a ubyte array.
reseed void reseed(size_t bits_to_collect): Seed this RNG using the entropy sources it contains.
