in thread Compact MD5 representation

OK, I'm (relatively) lazy. Looking at the source code for one Perl MD5 implementation, I see that the base64 output consists of A-Za-z0-9+/. Where does "=" come in? Why do you need to use 65 different characters?

    According to the docs for Mime::Base64, '=' is used to pad a Base64 encoded string to a multiple of four bytes.

    For MD5 hashes, they're always a multiple of four bytes anyway, so the '=' isn't needed. This is definitely good to know!
