As per the description above, you are not able to delete/remove the PDF files which are encrypted with certificates, Is that correct?
If you are the owner of the PDF file and have the certificate key, you can open it and can remove the security from Help>Properties after you open the PDF, and click the Security tab in the Properties dialog box to change the security settings.
Unfortunately, if you don't have the certificate keys, you won't be able to make any changes in the PDF document, or cannot delete them.
For more detailed information, you may refer to Securing PDFs with certificates, Adobe Acrobat
Feel free to update this discussion for any further assistance.
