A common form of this is '''ROT-13''', which is a Caesar Cipher with a shift of 13. This is especially notable because it is its own inverse (going forward 13 or backward 13 comes out the same because 13 is exactly half of 26). |

One is that the letters may have been moved forward through the alphabet a specific number of times. The alphabet here is treated as cyclic, meaning that after Z you go back to A. Note that in order to decode such a message, the solver would have to traverse the alphabet backwards.

A common form of this is ROT-13, which is a Caesar Cipher with a shift of 13. This is especially notable because it is its own inverse (going forward 13 or backward 13 comes out the same because 13 is exactly half of 26).
