This is an online version of the Caesar cipher wheel. Simply enter the shift value into the box and the outside “A” will rotate to the correct shift value.

To encode a message find the letter from the OUTSIDE you want to use and the letter next to it on the INSIDE is the coded letter you should write down.

To decode a message find the letter on the INSIDE you want to decode and the letter next to it on the OUTSIDE is the decoded letter.

To write a code (encrypt a message) work from the OUTSIDE to the INSIDE

To work out a code (decrypt a message) go from the INSIDE to the OUTSIDE
