❓ Frequently Asked Questions
What is ROT13?
ROT13 is a Caesar cipher that shifts letters by 13 positions. Applying it twice returns the original text.
Can I use other shift values?
Yes, you can use any shift value to encode or decode text using a standard Caesar cipher.
Does it affect numbers or symbols?
No, only letters (A–Z) are shifted. Numbers and symbols remain unchanged.
Does the ROT-N Cipher work offline?
