Plus a truckload of good random numbers. To do it right, a hardware RNG is in order. A PRNG really makes no sense, because if you have a PRNG that strong, why not just use it as a stream cipher?
that the actual increase in bandwidth for a three cypher system threshold in a practical encryption package like PGP would not be 2 to 1 since it likely compresses before encryption.)
To be fair, you need to compare compressed-and-split with compressed-only. This *is* going to be a factor-of-3 size hit. Eli ebrandt@hmc.edu
