Cryptographically random numbers

[Tuvas]

Thanks for the function Paul, it works alot nicer than the one I had in
my program... Now, with all of this knowledge, I'm going to be brave
and try out everything with AES. It seems to be working alright, I'll
debug this more on my own than I did with my RSA code, which turned out
to be full of bugs... I know the program sends the blocks in the
reverse order that would be expected, but, well, I'll get there.
Cryptology is fun:-)
