Coders and codebreakers alike will be fascinated by history's most mesmerizing stories of intrigue and cunning—from Julius Caesar and his Caeser cipher to the Allies' use of the Enigma machine to decode German messages during World War II.
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.

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.
The following is a list of cryptograms from Gravity Falls. There is a cryptogram during the credits of each episode. They use Caesar ciphers, Atbash ciphers, the A1Z26 cipher, and keyed Vigenère ciphers. Episodes 1-6 use the Caesar cipher, episodes 7-13 use the Atbash cipher, episodes 14-19 use the A1Z26 cipher, episode 20 uses a combined cipher (a combination of the A1Z26, Atbash, and Caesar ciphers), episodes 21-40 use the keyed Vigenère cipher. There is also a complicated combined…
