I just tried it, and it seems the free version doesn't electronically sign the document at all. It's neither encrypted nor signed, so anyone could modify it. I wish there were cheaper ways of getting X.509 certificates that linked back to a root cert in Adobe Reader. A decade back, I was using the P12 certificate issued by the ARRL (yes, I'm a radio nerd) to cryptographically sign PDFs. That certificate wasn't much better than self-signing: people could tell the document hadn't been modified, but they couldn't verify that I was who I said I was. They could if they installed the ARRL's certificate, but no-one did that. Heck, with a P12 certificate, my Brother AIO can generate signed and encrypted PDF scans ... chers, Stewart --- Post to this mailing list [email protected] Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
