What about the twofish implementation in loop-AES? does it have a nice assembler code just like the AES cipher? and is it pentium optimized? if not is there any chance we could get a pentium optimized one? actually I do care much about the speed of encryption/decryption, and as I read in some comparaisons Twofish is faster than Rijndael, especially with bigger key lengths, thats why I would choose twofish over Rijndael.
