Restrict what someone can do once they open the PDF with the password.
This encrypts the PDF with a password using 128-bit RC4 - the standard PDF viewers widely support for password protection, but a weaker cipher than modern AES-256. Good for keeping casual readers out; not a substitute for a compliance-grade encryption solution if you handle regulated data.
