Is data sent to a server?

No—encryption and decryption run entirely in your browser.

What if I forget the password?

AES-GCM is secure; without the password, the data cannot be recovered.

Encrypt and decrypt text locally with a password. PBKDF2 (100k iterations) → AES-GCM (256-bit).

Enter a password and the plain text to encrypt (or ciphertext to decrypt).
Click Encrypt or Decrypt; the key is derived from the password with PBKDF2.
Copy the result; decryption requires the same password. All processing is local.
