About Text Encryption / Decryption
Encrypt sensitive text with AES-256-GCM military-grade encryption using the Web Crypto API. Decrypt with a password. Your data never touches a server.
- AES-256-GCM military-grade encryption standard
- Password-based key derivation using PBKDF2 with 100k iterations
- Uses browser's native Web Crypto API
- Generates unique IV per encryption for replay protection
- Decrypts with the same password used to encrypt
Everything runs in your browser — your data never leaves your device.

- Set a strong password (encryption key)
- Click Encrypt or Decrypt and copy the result
Frequently Asked Questions
What encryption algorithm is used?
AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode), derived from your password using PBKDF2 with 100,000 iterations. This is military-grade encryption.
Is this secure?
Yes. AES-256-GCM is used by governments and banks worldwide. The encryption happens entirely in your browser using the Web Crypto API.
Can someone decrypt without the password?
No. AES-256 encryption is computationally infeasible to break without the correct password. Keep your password safe.
