Method Signature

 Protected Function RandomBytes(Count As UInt32, Optional Seed As MemoryBlock) As MemoryBlock

Parameters

Name	Type	Comment
Count	UInt32	The number of unpredictable bytes to generate.
Seed	MemoryBlock	Optional. The data to seed the PRNG with. (See remarks)

Return value

A MemoryBlock containing exactly Count unpredictable bytes, or Nil on error.
