First of all, let's create a simple document with inscription: "Hello World" and Save a document as the PDF file with Security Options:
// Let's create a simple inscription.
dc.Content.End.Insert("Hello World!!!", new CharacterFormat() { FontName = "Verdana", Size = 65.5f, FontColor = Color.Orange });
The next step is adding: Password Protection, EncryptionAlgorithm, Permissions
so.EncryptionDetails.UserPassword = "12345";
so.EncryptionDetails.EncryptionAlgorithm = PdfEncryptionAlgorithm.RC4_128;
so.EncryptionDetails.Permissions = PdfPermissions.Printing;
And the last step is saving a document as PDF
file
// Save a document as the PDF file with Security Options
dc.Save(@"d:\Download\DocumentProperties.pdf", so);
You may find extra info about Document Properties
Well done!
