9. Frequently Asked Questions (FAQ)
QWhat is ROT13?
ROT13 ("rotate by 13 places") is a simple substitution cipher that replaces a letter with the 13th letter after it in the Latin alphabet. Because 13 is half of 26, applying ROT13 twice restores the original text.
QCan I use custom rotation shifts?
Yes! While 13 is standard for ROT13, you can drag the slider from 1 to 25 to perform any classic Caesar shift.
QIs ROT13 & Caesar Cipher Encoder/Decoder free to use?
Yes, ROT13 & Caesar Cipher Encoder/Decoder is 100% free with unlimited usage. There are no subscriptions, account registrations, or hidden fees.
QIs my data safe when using ROT13 & Caesar Cipher Encoder/Decoder?
Absolutely. ROT13 & Caesar Cipher Encoder/Decoder operates on a client-side architecture. All transformations and computations take place locally inside your browser, meaning your confidential data and files are never uploaded to our servers.
QDoes ROT13 & Caesar Cipher Encoder/Decoder work on mobile devices?
Yes, ROT13 & Caesar Cipher Encoder/Decoder is fully responsive and optimized for mobile browsers across iOS and Android smartphones and tablets without requiring any app installations.
