Step-by-Step Guide to Using Secret PDF
Follow these instructions to protect your PDF documents using Secret PDF’s advanced DRM features.
Step 1: Install Secret PDF
Download and install Secret PDF from our homepage. Ensure your system meets the requirements: Windows Vista or later, .Net 4.0, Intel Core2 Duo 2.4GHz, 256 MB RAM, and 50 MB free disk space.
Step 2: Generate a Local Key
Open Secret PDF and select the option to generate a local key. This key uniquely identifies your computer and is used to lock the PDF to your device.
Step 3: Send the Local Key to the PDF Owner
Share the generated local key with the PDF owner securely. The owner will use this key to create an owner’s key for your specific device.
Step 4: Receive the Owner’s Key
The PDF owner will provide an owner’s key based on your local key. Save this key securely, as it’s required to open the protected PDF on your computer.
Step 5: Open the PDF with Secret PDF Viewer
Use Secret PDF’s built-in viewer to open the protected PDF. The viewer ensures the document cannot be copied, edited, printed, or converted, allowing only authorized viewing.
Step 6: Manage Permissions
As a PDF owner, use Secret PDF to set restrictions, such as locking the PDF to specific computers or preventing unauthorized sharing. The software uses AES and RSA encryption for robust security.
