hello
ROT decoding reverses the character shift performed during encoding. Each character is shifted backward by the same number of positions.
It reverses a Caesar cipher rotation applied during encoding.
Yes ROT13 encoding applied twice restores the original text.
No it is only a simple substitution cipher.
In puzzles, games, and message boards.
Yes if the shift value is known.
Yes the process runs locally in your browser.
