Text Encryption
Encrypt or decrypt any text with a password using AES-256-GCM authenticated encryption. Everything runs locally — your text and password never leave your browser.
How it works
Enter text & password
Paste the text you want to protect and choose a strong password.
Encrypt locally
Your password derives a key via PBKDF2 (250,000 iterations); AES-256-GCM encrypts the text in your browser.
Share safely
Copy the encrypted JSON anywhere. Only someone with the password can decrypt it back.
Frequently Asked Questions
Common questions about encrypting and decrypting text.
AES-256-GCM, an authenticated encryption standard widely used in banking and government systems, combined with PBKDF2-SHA-256 (250,000 iterations) for key derivation from your password.
No. Encryption and decryption happen entirely inside your browser using the Web Crypto API. Your plaintext, password, and ciphertext never leave your device.
The encrypted text cannot be recovered. There is no backdoor or "forgot password" option by design — that is what makes the encryption meaningful.
Only if it was encrypted with this exact format (AES-256-GCM + PBKDF2-SHA-256, produced by this tool). Other tools use different formats and are not compatible.
