Caesar Cipher (ROT-N)

Caesar cipher is a simple encryption technique. It uses the characters of an alphabet and shifts them by a certain number. This cipher is also called “ROT-N” like rotation by n characters. This tool lets you easily en- or decrypt texts. If you don’t know how often the alphabet is shifted, you can see all possible values quickly by using the slider at the bottom.

ROT13 with basic letters from A to Z is the most common Caesar cipher used for geocaching. ROT47 is a derivative that treats numbers and common symbols too. Advanced Caesar ciphers can operate with different alphabets or code words. See the alphabet handling page for further information about different alphabets and code words in GCTools.
