SystemRNG

Operating system specific cryptography secure random number generator.

It uses the "CryptGenRandom" function for Windows; the "arc4random_buf" function (not based on RC4 but on a modern and cryptographically secure cipher) for macOS/OpenBSD/NetBSD; the "getrandom" syscall for Linux 3.17 and later; and "/dev/urandom" for other Posix platforms. 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.
