Create a code using your cipher disk by following the procedure below.Inner Outer Cipher Disk

  1. Turn, or shift, the smaller circle to any other letter so that two different letters line up on the disk.
  2. In the photo to the right, a and U line up where a is the letter in the inner circle and U is the letter in the outer circle.
  3. The letters on the smaller, inner circle correspond to the letters of the actual message.
  4. The encrypted message will be the letters of the outer circle that correspond to the inner circle letters of the actual message.
