Basically I'm trying to find a CSRNG that can be seeded with a hash value or something similar and if I ran that piece of software on a different machine with that hash as the seed, it would produce the same numbers. A hash function usually means a function that compresses, meaning the output is shorter than the input. For the reference type, the each instance will generate a unique "random" number named hash code. It is therefore natural to ask which hash functions are most efficient, so we may chose intelligently between them. Random provides an interface to Ruby's pseudo-random number generator, or PRNG. The way it works is the user enters an input string, and the md5 algorithm will generate a 32-character string in hexadecimal characters. Hash Code - Google's Coding Competitions.
