Classic Cipher Playground

ROT13, Caesar, Atbash, Vigenère, ROT47, leetspeak and Morse — puzzle ciphers, not real cryptography.

About this tool

Reversible classical ciphers — not for security.

Algorithms

ROT13, Caesar (any shift), Atbash, ROT47, Vigenère (with key), Leet (1337) substitution, Morse code.
