Caesar cipher: Encode and decode online Method in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. The method is named after Julius Caesar, who used it in his private correspondence.
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.
Tool to decrypt/encrypt Vigenere automatically. Vigenere cipher is a poly-alphabetic substitution system that use a key and a double-entry table.
Tool to identify/recognize the type of encryption/encoding applied to a message (more 200 ciphers/codes are detectable). Cipher identifier to quickly decrypt/decode any text.
Cipher encrypter / decrypter. e.g. Caesar / ROT / and many other formats!
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 Cipher Translator (Decoder and Encoder) Emperor Julius Caesar developed one of the simplest and most well-known forms of cryptography. To communicate with his generals in times of war, Caesar changed a certain letter of the alphabet for the one that came 3 times in front of him.
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.

Vigenère cipher: Encrypt and decrypt online. Method of encrypting alphabetic text by using a series of interwoven Caesar ciphers based on the letters of a keyword. Though the 'chiffre indéchiffrable' is easy to understand and implement, for three centuries it resisted all attempts to break it.
