Coincidently, I was thinking about a RNG provided by the PLplot library. If nobody uses it except our example 21, no problem, since the code of RNGs is rather short, so no harm done here, and maybe some users find it useful though. A very good one (passed the diehard test), although maybe not good enough for encryption (don't think that will be a problem :), is the Mersenne Twister RNG http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html There is a C implementation available and the code is completely free. We could write a PLplot interface to this RNG, and then make the changes to all bindings. I volunteer to do that (that is the RNG interface, not all changes to the bindings), but only in two weeks, since I'm away for one week now.
