Hi Brent,

Thank you for using Syncfusion products,

We can add the security settings to the document as follow.

PdfDocument doc=new PdfDocument();
// Set encryption key. 
doc.Security.KeySize = PdfEncryptionKeySize.Key128Bit; 
doc.Security.Algorithm = PdfEncryptionAlgorithm.AES;
// Setting username and password to protect the document. 
doc.Security.OwnerPassword = "syncfusion"; 
doc.Security.UserPassword = "password"; 
// Allow print with full quality. 
doc.Security.Permissions = PdfPermissionsFlags.Print | PdfPermissionsFlags.FullQualityPrint; 

Please visit the below link for more information about the Pdf security.

Please let us know if you have any concern,

With Regards,
