About this tool
Scrambles the letters of your text using a secret key, and unscrambles it back with the same key. Works as a reversible obfuscation: the text becomes unreadable to anyone without the key, but is restored exactly when the correct key is entered. Useful for hiding spoilers, solutions to exercises, or trivial messages between friends.
How to use
- Paste the text you want to scramble in the box.
- Pick a secret key. Both sides (the one scrambling and the one unscrambling) need it.
- Click scramble to get the obfuscated result.
- To reverse, paste the scrambled text, type the same key, and click unscramble.
Frequently asked questions
- Is this secure like encryption?
- No, it isn't. It's a reversible scrambling trick, not a cryptographic cipher. Don't use it for sensitive information like passwords, personal data, or private communications. For that, use a real encryption tool.
- What happens if the key is wrong when unscrambling?
- The result stays unreadable, as expected. The function is deterministic: only the correct key restores the original text.
- Can I use any text as a key?
- Yes, any string works as a key. The longer and more random, the harder it is for someone to guess. But to be clear: this doesn't replace real encryption.
