Text Encrypt / Decrypt (AES-256)

Encrypt/decrypt text using AES-256-GCM with a password (PBKDF2), right on your device.

Encrypt and decrypt text with AES using your own password. Use it to protect sensitive notes before saving or sending them.

How to use Text Encryption (AES)

  1. Enter your text and a password.
  2. Click Encrypt to get the encrypted string.
  3. The recipient enters the correct password to decrypt it.

Frequently asked questions

If I forget the password, can I recover the content?

No. Without the password, decryption is impossible - keep your password somewhere safe.

Is the password sent anywhere?

No. All processing happens right in your browser, so your data is never sent to any server.
