Security settings not applied properly with Aspose.Pdf.Kit

Hello,

I have a problem while setting document security restrictions.

I'm using Aspose.Pdf.Kit to encrypt an existing document with specified security settings. Apparently code compiles and runs successfully but when I open the document it shows no controls to modify/create annotations.

I'm attaching both input (test.pdf) and output files (testoutput.pdf). Here are the passwords for testoutput.pdf:

Document Open Password: opass
Permissions Password: upass

I've tried to use both user password and master password to open the document but again these controls (create annotations) are not visible.

Am I missing something?

Thanks in advance for any help.

Regards,

Anis Ahmad
