Subject: Encoding

    text/* encoding can be read in you mail program
or any text editor.

Base64 is used to encode binary data in string so it can
get trought normal SMTP servers.

To get the binary file back, you must decode it with a base64
algorithm which is well known.

You may get info on this encoding here :
(section 5.2  Base64 Content-Transfer-Encoding)

Here is an already compiled tool :
(this one runs *nix & windows)

Have a nice day

At the risk of getting flamed (it will be worth it if I learn something
useful) I'd like to ask a question.
I've seen several cases where files have been sent to the list using
different encodings (examples below). How do you covert these back to the
original files (or can you?)
