Lief, >but isn't that true of the twofish algorithm too? >So why did Gene make an MI version? No; TwoFish has been granted free use rights for *Public. One reason Gene needed an MI version is the way the TwoFish algorithm reuses the results of integer operations as part of the encryption process. When used on a single platform, the algorithm would be symmetrical, ie would decrypt correctly. But the Big-Endian vs Little-Endian differences in integer storage formats in the 400 vs Intel platforms means the files would not be cross-platform compatible. So Gene's MI program does a swap on every 4 bytes to mimic the Intel format to get cross-platform support.
