Online ROT13 Encryption Tool

The ROT13 Encryption tool is a simple and fast method for encoding or decoding text with just one click. This tool is useful for educational purposes, light security, or temporary text obfuscation.

What is ROT13?

The ROT13 algorithm is one of the simplest encryption methods, replacing each letter with the thirteenth letter after it in the English alphabet. For instance, the letter A becomes N, and vice versa. Interestingly, this encryption is bidirectional and symmetric; meaning if you pass a text through ROT13 twice, it returns to its original state.
