For Pseudo Random Numbers Generator based on linear recurrences, using SHA-1 over the PRNG's output appears to be the mostly common approach to make the output cryptographically secure.

Are you committed to a particular RNG? Blum Blum Shub is rather computationally intensive, but it may be less so than decorrelating some other PRNG with a hash. -=rsw
