Hi Adobe support, Greetings from SK Oilfields! Need support for working with signed pdf files, need to understand how to remove the signature and remove the certificates from a pdf file. Also, we expect to learn about how can we add certificates and signatures to pdf files. We have an Adobe Acrobat Pro DC licensed version. Please help. Thanks.

Hey @JR Boulay ,
Thanks, this partly helped.
I am still doubtful of how to remove the Certified-Signatures.
Also, how does Adobe identify that a PDF was signed by a user A when user B and A are using the same licensed account in Adobe Acrobat?

Hi @JR Boulay ,
Isn't this the same article as the previous one?
Making myself more clear,
I need help with Editing Signed and Certified PDFs.
Also, I would like to know of how does Adobe Identify who is signing the PDF? ... This question comes to us because, we have one license for Adobe acrobat PRO DC which allows two users to use the software at two remote devices with the same account.
Now, if someone has signed using a digital signature(maybe that is when it shows signed and certified), the other user cannot edit it. Also we cannot remove the security as it says:
You cannot change security on this document because the document is signed or certified.
You use a license of Adobe Acrobat for two users?
Yes, the regular one which allows two computers to use the license at once.
You have made a mistake, and must correct it. The regular license MUST NOT BE SHARED. if you follow the license rules, the situation you describe ("users A and B share the same account") cannot arise.
"I need help with Editing Signed and Certified PDFs. " You should not expect to be able to do this, as I said. Your workflow needs fixing if this seems to be a requirement.
"Also, I would like to know of how does Adobe Identify who is signing the PDF? ... "
If signing with a local certificate the identity comes from the certificate. You need to decide what level of proof of ID you require; a self-sign certificate is only really useful for the signer to verify that it has not been changed. It has no legal value or proof of anything. A certificate issued by a certifying authority carrries legal proof of identity, but of course your users must not share the signing certificate.
" we have one license for Adobe acrobat PRO DC which allows two users to use the software at two remote devices with the same account. "
I have frankly never heard of such a license. Are you sure you haven't just got the regular license that allows one person to install it and use it at two computers? It is a breach of the license is any other person ever uses the software, whether on the same or a different computer, and the license absolutely can't be split or shared. (This is a common misunderstanding, but still a serious breach). You MIGHT have an enterprise account which is licensed per computer, but the user is still expected to personally sign in. Such a computer should not, though, be set up with personal certificates, that workflow doesn't work. However an enterprise wide certificate store may work if the users have separate Windows logins controlled from the domain controller.
I'm using the regular license, please read the context.
"Isn't this the same article as the previous one?"
Yes, sorry for the mistake
No problem, any solution?
It is VITAL to make an archive copy before setting security or signing. You can't always go back. This is the most important lesson. That and how to be really, really organised with the archive copies.
