Random

Functions for generating pseudo-random numbers.

The algorithm used is a "linear congruential generator", the same one used in scala.util.Random or in java.util.Random.

Note that the generated numbers are not cryptographically secure. Consider instead using java.security.SecureRandom to get a cryptographically secure pseudo-random number generator for use by security-sensitive applications.
