JBase64 analyzes and converts Base64 formats.

Base64 is the name of the encoding system used to store attachments in emails. Indeed, an email is a text. Or, the attachments can be of any type: images, music, binary files executable or not, ... this is why the attachments are encoded as text included in the body of emails. It is the email management software, Eudora, Koma-mail, Outlook express, Thunderbird, ..., or the site of the email address provider, GMail, Hotmail, Yahoo, ..., who does the coding of Base64 attachments, includes this code in the body of the email, sends it and, in reverse, when receiving a message containing encrypted attachments, decodes them to restore the original attachments, and save them to separate files in the message. Normally, everything is transparent to the user and everything goes well. So, why worry?
Well, in computer science, nothing is ever as simple as it should be, and, consequently, it happens that this beautiful mechanism no longer works. I happened to receive emails that I knew they had attachments, and not to see them or have any way to access them, simply because the software used by the sender had decided to put them in an unusual place...

So I decided to write JBase64. This software allows:

-to have information on any file, when you want to know if it contains Base64 code.
-to decode a file encoded in Base64.
-to encode any file in Base64.

JBase64 supports Base64 encoding and its Base64url variant; see Wikipedia article "Base64".

The program does not need installation: copy it and run JBase64.exe. It can also be run from a U.S.B key. This program takes up little space and can be useful someday or if you study base64. Tip: Make a small software toolkit in which you will place it.

This program requires Windows XP or later. It's a 32-bit program.
