String Obfuscator
Obfuscate sensitive strings in code snippets.
How to Use
- Paste the string you want to obfuscate into the input field — API keys, test data, or any sensitive text.
- 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).
- 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.
