A monoalphabetical substitution cipher uses a fixed substitution over the entire message. The ciphertext alphabet may be a shifted, reversed, mixed or deranged version of the plaintext alphabet.

Tool for encoding and decoding with the Caesar cipher, a simple and famous shift cipher that replaces each letter with another one further down the alphabet. Compatible with ROT13 and other variants.

This multi decoder is designed to support a large number of codes and ciphers. Not all codes and ciphers have keywords, alphabets, numbers, letter translation, etc so if the code or cipher doesn't require it, those fields will be ignored.

Stuck with a cipher? This AI tool will help you identify the type of cipher, as well as give you guidance about how to solve it. This cipher identifier recognizes most common cipher types and codes. Text Options... Note: To get accurate results, your ciphertext should be at least 25 characters long.
