0xFFFF Posted July 5, 2013 Share Posted July 5, 2013 Hi all, Is anyone familiar with invalidating PDF certificates / removing document security? I have a number of documents which require an installed certificate (which I have) and a password for said certificate. Is there a way to remove this from a PDF? I don't have the public key. I have tried invalidating the certificate using some perl script magic but the document permissions still prevent me from clearing and removing the invalid certificate.
