Sending sensitive PDFs via email? Encryption ensures only intended recipients can access the content.
Understanding PDF Encryption
PDF encryption scrambles document content using a password. Without the correct password, the file is unreadable.
How It Works
- Your PDF content is encrypted using algorithms (like AES).
- A password becomes the decryption key.
- Opening the file requires entering the password.
- Correct password decrypts and displays the content.
