No API key required. Encrypt PDFs into a secure .enc file using AES-GCM with password protection, and decrypt them back to PDF using the same page.

We derive a key from your password using PBKDF2 and encrypt with AES-GCM (Web Crypto API).
The encrypted file stores: salt (16 bytes) + iv (12 bytes) + ciphertext.
This is NOT an Adobe-compatible password — recipients must decrypt using this tool to get the original PDF.
