The advantages of a provable prime are overhyped. The probability of not
finding a prime if you use a probablistic approach are extremely small,
and algorithm for proving primality AFAIK is very slow. Already
generating primes is slow enough that people do not want to do it. 
And, AFAIK if you use a non-prime in RSA you will not get the right
answers when you try to decrypt. So you will soon discover that you do
not have a real prime. Ie, speed is probably more important that
provability in this case. 
So what is the speed of your implimentation vs the speed of
probabilistic approaches?
