About this tool
Encode and decode classic codes: ROT13, ROT47, Caesar shift, Atbash, Vigenère, Morse code, Braille (grade 1), the NATO spelling alphabet and 5-bit Baudot (ITA2).
Letter ciphers shift or mirror A–Z and keep case and punctuation; Vigenère shifts by the letters of a key. Morse uses the ITU alphabet with “/” between words, Braille the Unicode braille patterns with number and capital signs, Baudot the ITA2 table with letter/figure shifts.
Example: “SOS” in Morse → ... --- ...
These are puzzles and historical codes, not security: they can be broken in seconds. Use real encryption for anything private.
