In connection with my work I needed a simple tool to encrypt small text messages. I did not find anything I liked so I decided to make a tool myself. And why not create it as a Google Gadget that can be inserted today almost anywhere.

Description
This ultra simple gadget can encrypt and decrypt a text message using a given secret key. This is done using the XXTEA algorithm. The encrypted text output is Base64 encoded. Currently the gadget is translated into english (default) and danish.

Please feel free to use this gadget wherever you like.
