ROT13 & Caesar Cipher Cryptor / Decryptor

Q: Why is ROT13 symmetric?

Because the English alphabet has 26 letters, applying a 13-character rotation twice (13 + 13 = 26) returns the exact original plain text.

Encode and decode text using ROT13 or custom Caesar shift offsets (1–25). Obfuscate spoilers, puzzle answers, and secret codes.
