Why do people do tripple DES and *shudder* tripple IDEA ^^^^^^^triple.
instead of doing some form of non-redundant secret splitting and then encrypting with multiple keys.
Because people like algorithms that work quickly and don't expand their data by a factor of two or three. As I've noted before, in spite of protestations, the evidence is good that splitting and encryption doesn't by you much over simple superencipherment. Perry
