There's likely a variety of reasons for this; some historical, some mathematical. Certainly you can convert the number of bits to a number of bytes by dividing by 8 _if_ you prefer that for some reason, but a _lot_ more people will know what you mean if you say, for example, "128-bit AES" than "16-byte AES". (Never mind "AES-128" versus "AES-16", the latter of which seems likely to just be confusing.) So for communicating with others, I _really_ suggest using the more common form. -- Michael Kjörling • https://michael.kjorling.se • michael@xxxxxxxxxxx “Remember when, on the Internet, nobody cared that you were a dog?” _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx https://www.saout.de/mailman/listinfo/dm-crypt
