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.
