PdfProcessing: Provide API for setting different permissions when exporting encrypted PDF document
This would allow to encrypt documents only with Owner Password and not showing password dialog when disabling some PDF features permissions. The customer should be able to disable printing, text and graphic selection and extraction, page rotations and others. The full specification of all permission bits may be seen in Table 3.20 on page 124 in PdfReference 1.7. On page 120 in PdfReference 1.7 are described the User and Owner passwords.

Hello Fadi,

I am happy the feature is working as expected in most of the PDF viewers. 

As for the Nitro PDF, I am afraid I cannot suggest anything other than reporting this issue to their support.

You are correct, appears the PDF viewer is the issue.

Nitro PDF is the only one that reports that page extraction is allowed.

Hello Fadi,

I tried to reproduce the described behavior with these settings but on my end, it works as expected (check the attached record.gif).

I am attaching the sample project I created in order to test this functionality as well. Please, feel free to modify it in a way closer to your scenario.

Maybe I am missing something in the setup, if so, please let me know. 

On the other hand, it could be document-specific. If so, please open a new ticket and send us a sample document in order to deeper investigate the case. I must assure you we treat all client files in a strictly confidential manner and for testing purposes only.

Thanks for adding this new feature.

When setting Changing to None, the Page extraction is still enabled.

 _provider.ExportSettings.UserAccessPermissions = new UserAccessPermissions
            {
               Copying = CopyingPermissionType.None,
               Changing = ChangingPermissionType.None,
               Printing = PrintingPermissionType.HighResolution
            };

Hi Hiep,

Indeed, you can set the marked (and not only permissions) with this feature implemented.

You can do this in the following way:

PdfExportSettings settings = new PdfExportSettings();
settings.OwnerPassword = "123";
settings.IsEncrypted = true;
//! This permissions are exported only if settings.IsEncrypted
UserAccessPermissions permissions = new UserAccessPermissions
{
	Printing = PrintingPermissionType.HighResolution,
	Changing = ChangingPermissionType.FormFieldFillingOrSigning,
	Copying = CopyingPermissionType.TextAccess,
};
settings.UserAccessPermissions = permissions;
provider.ExportSettings = settings;
provider.Export(this.fixedDocument, output);

We can set permissions programmatically for these settings?

Hello Simon,

I am sorry to hear that you need to use a separate library for this.

Your vote is already added. Hopefully, this will be included in our roadmap soon.

Please add our vote.

We issue digital certificates as secured pdf's which we need to ensure cannot easily be edited by an end user. This seems to be a pretty fundamental omission from the api and means we can't use your library without subsequently passing the output through another utility to implement the required security. 

We have had to revert to a different library until this feature is implemented.

Hi all,

The task is not scheduled for implementation in the current release and I am afraid I cannot share any timeframe it might get implemented. Please, make sure to cast your vote for it and continue following it so you can receive updates about status changes on it.
