Remarks

The PDFSecurityOptions class is used as the type for the SecurityOptions and used to read and write the security and encryption options to use with PDF files.

When reading PDF documents, PDFDocument.SecurityOptions will always be populated automatically when the PDFDocument object is initialized.

When writing PDF documents, the following methods of the PDFFile class will use the security options set in PDFFile.SecurityOptions when updating or created a PDF file:

If the value of PDFFile.SecurityOptions is null, then the PDFFile will not encrypt the result PDF file.

User Password and Owner Password

There are two different types of passwords to protect different aspects of a PDF file with a password:
