Frequently Asked Questions
How does ROT13 work?
ROT13 shifts each letter 13 positions in the alphabet. Since there are 26 letters, applying ROT13 twice returns the original text.
Is ROT13 secure?
No, ROT13 is not encryption. It's just obfuscation and can be easily reversed. Use it for hiding spoilers, not secrets.
