It is always the length you pass in. CFB mode behave similar to a
stream cipher.

I see - I think. So MAXSIZE=64 would work, even if the passed in string
was less than MAXSIZE, but I should expect upon decryption to get a
string MAXSIZE in length back?

I believe the answer to that question is 'no', it will only return the
same string (and therefore same size) as that it was passed - correct?


As always, thanks for your help.


Tod
