Hi,
I've been looking for some details about the
DES-CBC3 cipher and I haven't been able to find them on the mailing list
archives. Is DES-CBC3 encrypting 3 times with three different keys (EEE) or is
it encrypting and decrypting with two keys only (EDE)? If I understand correctly
the effective key strength is not 168 but 112: are marketing documents usually
referring to the strength as 168 bits anyway?
Thanks!
Vincent
