To be able to replay a game on various architecture saving only the seed

This is really untrue in a lot of applications for instance in cryptography.
But I do not know if random.ml is good enough for assymetric cryptography
(where the secret key in the seed and the coding is simply xor with a
random sequence of bit)
This require not only passing all randomness test, but also making it
hard to recover the key from
a generated sequence of random bits.
