FAQ

What is a ROT cipher?

A ROT (rotate) cipher is a simple substitution cipher that replaces each letter in the text with a letter some fixed number of positions down the alphabet. For example: ROT1: A → B, B → C, etc. ROT13: A → N, B → O, etc. ROT25: A → Z, B → A, etc.

How does case preservation work?

The tool maintains the original case of letters while applying the ROT cipher: Uppercase stays uppercase (A → N) Lowercase stays lowercase (a → n) Numbers and special characters remain unchanged

What characters are affected?

The ROT cipher only affects letters (A-Z and a-z). All other characters remain unchanged: Numbers (0-9) stay the same Punctuation remains unchanged Spaces and line breaks are preserved Special characters are unaffected

Is ROT encoding secure?

No, ROT encoding is not secure encryption. It should only be used for: Simple text obfuscation Creating puzzles or games Learning about basic ciphers Hiding casual text (like spoilers) Never use ROT encoding for sensitive information.
