Text Encoder-Decoder HTML Code

A code that can encode and decode the text and the number you entered. When you enter text or numbers, then click the 'encoding' button, a pop-up window will display your encoded text.

Very interesting, you can encode your e-mail messages to your friends, and then ask them to visit your page to decode it.
