String Obfuscator

Obfuscate sensitive strings in code snippets.

How to Use

  1. Paste the string you want to obfuscate into the input field — API keys, test data, or any sensitive text.
  2. Choose your obfuscation method: ROT13 (shifts each letter by 13 positions), Reverse (reverses the character order), Leetspeak (replaces letters with similar-looking digits and symbols), or Unicode Escape (converts each character to its \uXXXX escape sequence).
  3. Copy the obfuscated string and safely share or store it without exposing the original value.

Frequently Asked Questions

Is obfuscation the same as encryption?
No. Obfuscation makes text hard to read but can be reversed by anyone with the tool. Encryption requires a key and is cryptographically secure.
When should I use this?
For sharing code snippets or logs where you want to hide API keys or sensitive values from casual viewing — not for production security.
Which obfuscation method is most secure?
None are truly secure. Masking shows partial data. Hex encoding and reversal are trivially reversible. Use encryption for real security.
