Ciphers and Codes: Caesar, Morse, ROT13 and NATO
Classic ciphers and codes for puzzles, escape rooms, lessons and curiosity. Each tool encodes and decodes in both directions and explains how the method works.
These ciphers are for fun and learning. They are easy to break and should not be used to protect real secrets.
Morse Code TranslatorTranslate text into Morse code and Morse code back into text.Caesar Cipher ToolShift letters forwards or backwards with a Caesar cipher, including ROT13.NATO Phonetic Alphabet ConverterSpell out text with the NATO alphabet, or turn code words back into letters.ROT13 and Simple CiphersEncode and decode ROT13, ROT5, ROT47, Atbash, A1Z26 and affine ciphers.Vigenere CipherEncode and decode text with the Vigenere cipher using a keyword.Rail Fence CipherEncode and decode the rail fence zigzag transposition cipher with any number of rails.
No tool matches that. Try a shorter word.
