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.
