Post subject:  pdfsharp document security
I was wondering if there was a way to protect the document built using PDFSharp from editing but not require a password to open it. I see the security sample in the documentation and it totally works for me, but i'd have to enter the password each time.

Thanks in advance for any help.

Yes, can be done.
I'll have to look up the details.

The "trick" is setting an OwnerPassword but no UserPassword.

Here's a code snippet for a PdfDocument document:
Code:
document.SecuritySettings.DocumentSecurityLevel = PdfDocumentSecurityLevel.Encrypted128Bit;
document.SecuritySettings.OwnerPassword = Guid.NewGuid().ToString();
document.SecuritySettings.PermitModifyDocument = false;
document.SecuritySettings.PermitExtractContent = false;
document.SecuritySettings.PermitAnnotations = false;
document.SecuritySettings.PermitAssembleDocument = false;
document.SecuritySettings.PermitFormsFill = false;
