SystemEntropy alias SystemEntropy(Elem, string pathToRandom = defaultPathToRandom, string pathToStrongRandom = defaultPathToStrongRandom) = WrappedStreamRNG!(SystemEntropyStream!(pathToRandom, pathToStrongRandom), Elem): Reads random entropy from a system-specific cryptographic random number generator. On Windows, this loads ADVAPI32.DLL and uses RtlGenRandom. On Posix, this reads from a file (by default, "/dev/urandom" normally and "/dev/random" when Yes.PredictionResistance is requested). The speed and cryptographic security of this is dependent on your operating system.

HashDRBGStream struct HashDRBGStream(TSHA = SHA512, string custom = "D Crypto RNG", EntropyStream = SystemEntropyStream!()): The underlying stream-like interface for SystemEntropy.
SystemEntropyStream struct SystemEntropyStream(string pathToRandom = defaultPathToRandom, string pathToStrongRandom = defaultPathToStrongRandom): The underlying stream-like interface for SystemEntropy.
WrappedStreamRNG struct WrappedStreamRNG(RandomStream, StaticUByteArr)
struct WrappedStreamRNG(RandomStream, UIntType): Takes a RandomStream (ex: SystemEntropyStream or HashDRBGStream) and wraps it into a UniformRNG InputRange.

HashDRBG template HashDRBG(Elem, TSHA = SHA512, string custom = "D Crypto RNG", EntropyStream = SystemEntropyStream!()): Cryptographic random number generator Hash_DRBG, as defined in NIST's SP800-90A.

defaultPathToRandom enum string defaultPathToRandom;: The path to the default OS-provided cryptographic entropy generator. This should not be a blocking generator.
defaultPathToStrongRandom enum string defaultPathToStrongRandom;: The path to an OS-provided cryptographic entropy generator to be used when Yes.PredictionResistance is requested. This should be at least as strong as defaultPathToRandom. But unlike defaultPathToRandom, this may be a generator that blocks when system entropy is low.
