Random::Secure generates random numbers from a secure source provided by the system.
It uses a cryptographically secure pseudorandom number generator (CSPRNG) for cryptography and secure usages such as generating secret keys, or to seed another pseudorandom number generator (PRNG).
Random::Secure.rand(6) # => 4 [1, 5, 6].shuffle(Random::Secure) # => [6, 1, 5]
