PDF certificate security...


0xFFFF

Recommended Posts

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.
