module Random::Secure


Generates random numbers from a secure source provided by the system.

For example arc4random is used on OpenBSD, whereas on Linux it uses getrandom (if the kernel supports it) and fallbacks on reading from /dev/urandom on UNIX systems.

Random::Secure.rand(6)            # => 4
[1, 5, 6].shuffle(Random::Secure) # => [6, 1, 5]
