AES-256 Text Encryption Tool

This tool uses the Web Crypto API built into your browser to encrypt text with AES-256-GCM — the same standard used by banks and governments. Your password is never stored or sent anywhere. All encryption and decryption happens locally on your device.

How to Encrypt Text

  1. Paste or type your plain text in the input field.
  2. Enter a strong password — use the generator if needed.
  3. Click Encrypt Text.
  4. Copy the encrypted output and share or store it safely.
  5. Use Decrypt mode with the same password to recover the text.

Frequently Asked Questions

AES-256-GCM (Galois/Counter Mode) is used — one of the strongest symmetric encryption algorithms available. The key is derived from your password using PBKDF2 with 100,000 iterations of SHA-256.

No. This is true encryption — without the exact password, decryption is mathematically impossible. There is no back-door or recovery option. Always keep your password safe.
