Problems with 'Secured PDF' files

Hi @Rony Guerra

Thank you for reaching out to us through our Community Forums!

I went to that website and downloaded a copy of the www-spdf-test.pdf file. This will not open either using web browsers since it requires a FileOpen plugin. 
Unfortunately, FileOpen encryption support was deprecated back in Nitro PDF Pro 12. You may use other PDF software that supports FileOpen encryption. 

Kind regards,
