Tool to decrypt/encrypt with Caesar cipher (or Caesar code), a shift cipher, one of the most easy and most famous encryption systems, that uses the substitution of a letter by another one further in the alphabet.
This tool uses AI/Machine Learning technology to recognize over 25 common cipher types and encodings including: Caesar Cipher, Vigenère Cipher (including the autokey variant), Beaufort Cipher (including the autokey variant), Playfair Cipher, Two-Square/Double Playfair Cipher, Columnar Transposition Cipher, Bifid Cipher, Four-Square Cipher ...
Caesar ciphers are commonly used in children's decoder rings to create simple codes and puzzles to teach cryptanalysis. Notably, decoder rings themselves are a modern version of the Caesar wheel, an early decryption tool used to break the Caesar cipher.
Caesar cipher is one of the single transliteration ciphers that encrypts by replacing the characters in the text with other characters. Character replacement is performed by shifting the characters from "A" to "Z" among the 26 characters of "ABCDEFGHIJKLMNOPQRSTUVWXYZ".
Our online tool brings this ancient cipher into the digital age, allowing you to easily encrypt or decrypt text with a custom shift key. Whether for educational purposes, cipher challenges, or just for fun, our tool is designed to be intuitive and easy to use.
