Password Decoder Wheel
Scramble and decode your internet passwords, escape room clues, and top secret messages! Instructions are printed right on this waterproof, durable, flexible, vinyl cipher wheel.
Rotate the inner disk to display a secret number in the KEY window to set the code shift of your message. The inner disk will have the letters of your true message or plain text and the outer disk will have the letters of your encoded message or cipher text. If you set 1 in the window, there is a shift of 1, and A=B, B=C and so on.
TO ENCODE OR SCRAMBLE:
First choose your secret code shift number. Example: a code shift of 17 is set by turning the inner disk until 17 is seen in the key window. Let's say we want to encode the word HELLO. H on the inner disk is next to Y on the outer disk. Across from E is V, L=C, L=C again, and O=F. So with a code shift of 17, HELLO is encoded to YVCCF. Encoding once provides a 1:25 security ratio. Encoding more than once with two or more keys provides an even higher security ratio.
The code shift number must be known to decode a scrambled password or message. Once the key is set to the right code shift number, the code can be deciphered working from the outer to the inner disk.
