You won't get much argument from me about that. Nonetheless, lots of code `knows' that it is `unsigned char[8]' (it _is_ DES, after all, where all the keys and operations are on 64 bits). Unfortunately, some of these practices were extended to the triple-DES interfaces as well... Cheers, -- Jacques A. Vidrine <nectar@celabo.org> http://www.celabo.org/ NTT/Verio SME . FreeBSD UNIX .
