then you are seeing the effect of someone who didn't use an algorithm
optomized for speed. if you do a similar thing with PGP you'll notice it's
much faster - pgp also has installed things to make finding the password
more difficult and from knowing how full an archive is -- I doubt UC2 has
such stringent standards.

well, I'm 95% sure that each of Rand1 and Rand2 are 56 bits but I can't be
bothered to double check for sure.
