SystemRNG

Operating system specific cryptography secure random number generator.

It uses the "CryptGenRandom" function for Windows and "/dev/urandom" for Posix. It's recommended to combine the output use additional processing generated random numbers via provided functions for systems where security matters.

Remarks: Windows "CryptGenRandom" RNG has known security vulnerabilities on Windows 2000 and Windows XP (assuming the attacker has control of the machine). Fixed for Windows XP Service Pack 3 and Windows Vista.
