I recently found myself doing some web development where two systems talked to each other over SOAP. XML documents were being passed back and forth and were encoded with Base64. To make sure everything was working I had to be able to encode and decode these Base64 strings so I knocked up a little application that I could copy and paste text into and convert back and forth from Base64 to English. It looks like this:

Since I found it useful (and will no doubt use it again in the future) I thought I’d put it up here in case anybody else finds they need a tool to do the same thing. It runs on Windows only (all versions from Windows 98 upwards) and requires that you’ve installed the Microsoft .NET Framework 2.0 first – which you can download here.

As it’s a developer’s tool I’ve not bothered putting an installer together. To run it simply download the following ZIP file and copy the executable (along with the readme file if you wish) into a place of your choosing and run it:

Download the ZIP package (version 1.0 – 180KB)

Hopefully you’ll find it useful!
