cryptography - Cross-platform cross-language cross-everything actually deterministic random number generator

Question

I'm looking for an algorithm to generate random numbers from a given seed but with the particular requirement that it will always generate the same sequence of number regardless of the underlying computer architecture or language implementation.

I already know of Mersenne Twister, however, the numbers it generates differ when using different implementations (i.e. C MT vs Javascript MT).

Do algorithms with this property exist? Also, I don't need a state-of-the-art RNG, I don't even need it to be cryptographically secure, I just want to drive a "random" simulation on one place and have it follow the same behavior on a different implementation.

Answer 1

If you don't need a cryptographicly secure RNG then MT or LCG would do. Still, some stream ciphers are pretty easy to implement in many languages, or already available, so these are viable paths. All of these are deterministic, same seed results in the same random numbers, and quite fast.
