Robust Random Number Generation *

Question

I'm looking for a performant, reasonably robust RNG using no special hardware. It can use mathematical methods (Mersenne Twister, etc), it can "collect entropy" from the machine, whatever. On Linux/etc we have a drand48() which generates 48 random bits. I'd like a similar function/class for C++ or C# which can generate more than 32 bits of randomness and which low-order bits are equally as random as high-order bits.

It doesn't have to be cryptographically secure but it must not use or be based on the C-language rand() or .NET System.Random.

Any source code, links to source, etc. would be appreciated! Failing that, what TYPE of RNG should I be looking for?

Answer

For C++, Boost.Random is probably what you're looking for. It has support for MT (among many other algorithms), and can collect entropy via the nondet_random class. Check it out! :-)
