How to Use This Tool

  1. To send a secret message: Type your message in the Encrypt tab, create a strong password, and click Encrypt.
  2. Share the encrypted text with your recipient through any communication channel (email, text, etc.).
  3. Share the password separately through a different channel (phone call, in person, different app).
  4. To read a message: Paste the encrypted text in the Decrypt tab, enter the password, and click Decrypt.
🛡️ Security Note: This tool uses AES-256 encryption, the same standard used by governments and banks. All encryption/decryption happens entirely in your browser — no data is ever sent to any server.
