This makes it easier to generate random numbers or fill a buffer with random data in a cryptographically secure way. This also replaces existing usages of RNG functions in the codebase: * <random> is pretty hard to use correctly, and std::random_device does not give enough guarantees about its results (it's implementation-defined, non cryptographically secure and could be deterministic on some platforms). Doing things correctly is error prone and verbose. * rand() is terrible and should not be used especially in crypto code.
