Encrypt / Decrypt Text
How to use this encryption tool
- Choose "Encrypt" or "Decrypt" mode at the top.
- Type a password and the text you want to process.
- Click "Run" — to decrypt later, use the exact same password on the encrypted output.
How does this work?
Your password is stretched into an encryption key using PBKDF2 (100,000 iterations), then used with AES-GCM to encrypt your text. The random salt and initialization vector are bundled with the output so you can decrypt it later with the same password — everything happens locally in your browser.
What happens if I forget the password?
The text is permanently unrecoverable. There is no backdoor or master key — that's what makes this a real encryption tool rather than simple encoding.
Is AES-GCM considered secure?
Yes, AES-GCM is a modern, authenticated encryption standard widely used in TLS, VPNs, and government systems. It's one of the most trusted algorithms available today.
