How to test a cryptographically secure random number generator

This term "cryptographically strong" is often used to describe an encryption algorithm, and implies, in comparison to some other algorithm (which is thus cryptographically weak), greater resistance to attack. But it can also be used to describe hashing and unique identifier and filename creation algorithms. See for example the description of the Microsoft .NET runtime library function Path.GetRandomFileName. In this usage, the term means "difficult to guess". WebApr 13, 2016 · Even if seeded with something else, a non cryptographically secure pseudo random number generator can reveal its state should enough values be captured.
