In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.

DIY Cipher wheel, with templates. It uses a pin and eraser to spin the wheels, but think you can use a butterfly clasp just as well.


Julius Caesar was the first to encode communications, using what has become known as the Caesar Cipher.

Cipher Wheel Decoder Necklace / Ceasar Cipher Disk / Secret Message Cryptograph Pendant

This cipher wheel necklace is both lovely to look at and precisely made. The top disk spins freely, allowing the pendant to be used for encoding and decoding


The Caesar shift cipher is actually 26 different ciphers, one for each letter of the alphabet. ROT1 is just one of these ciphers. A person only needs to be told which Caesar cipher was used in order to decipher a message. This cipher is the basis for many more complex ciphers, but on its own does not allow great protection of a secret message, as checking 26 different cipher keys does not take a relatively great amount of time.

Gravity Falls ok for those who don't know the code and the end of the episode there is some letters so every letter you do 3 letters back and there's a code some r numbers so u do the alphabets number
