Caesar Shift

This uses the basic Caesar Shift to Encode and Decode a message. The message is created by clicking the buttons. Slide the Roman Soldier up and down the column to set the shift amount then click the Encode button. UNDERSCORE is used instead of SPACE to reduce confusion in the encoded message.

The amount you shift it by is at the top I presume? Otherwise it is superb if it was done by a KS3.

Yes. The slider has a small text number above it that ranges from -25 to 25. A positively shifted message can be returned to its starting value if a similar negative shift is then given.
