WrappedStreamRNG

Takes a RandomStream (ex: SystemEntropyStream or HashDRBGStream) and wraps it into a UniformRNG InputRange.

Note that, to conform to the expected InputRange interface, this must keep a copy of the last generated value in memory. For security purposes, it may occasionally be appropriate to make an extra popFront() call before and/or after retreiving entropy values. This may decrease the chance of using a compromized entropy value in the event of a memory-sniffing attacker.

Members

Functions

popFront void popFront(): Implements an InputRange

Manifest constants

empty enum empty;: Infinite range. Never empty.
isUniformRandom enum isUniformRandom;: Mark this as a Rng
min enum min;: Smallest generated value.

Properties

front StaticUByteArr front [@property getter]: Implements an InputRange
max StaticUByteArr max [@property getter]: Largest generated value.

Variables

stream RandomStream stream;: Access to underlying RandomStream so RNG-specific functionality can be accessed.
