Now you can send secret message to your friends ... using cryptogtaphy*.
Type your message, and your special SHIFT (such as 1 or 2, etc), then press "Encode".
Your friends can decode the message when you tell them the Key Value.
How does it work?
It uses a simple method of Cryptogtraphy (the study of secret messages) called "Key Offset".
Each letter in your message is moved forward in the alphabet a number of places (based on your Key Value)
Try typing in "abcd" and use a Key Value of 1, and you will get the idea ... I did say it was simple!
Just don't tell anyone how it works, or they may figure out how to decode your message!
Maybe you can think of a better method?
Of course, this is easy to crack. Be careful! All the fame and glory for this tool goes to mathisfun.com.
