ROT13 Decoder: Decode ROT13 Encoded Text Instantly
A ROT13 Decoder is a text decoding tool used to convert ROT13 encoded text back into its original readable form. ROT13 is a simple letter substitution cipher that shifts each alphabetic character by 13 positions. Because the transformation is symmetrical, decoding simply applies the same process again.
This tool works by reversing the ROT13 transformation applied to encoded text while leaving numbers, symbols, and spaces unchanged. It allows users to instantly reveal hidden or obfuscated text without manual decoding.
The ROT13 Decoder is commonly used for:
- Decoding ROT13 encoded messages
- Revealing hidden or obfuscated text
- Solving puzzles and challenges
- Learning basic cryptography concepts
- Educational and demonstration purposes
By using a ROT13 Decoder, users can quickly restore encoded text to its original form. It is useful for students, developers, writers, and anyone working with simple text encoding methods.
FAQ
