I'm trying to use an existing personal certificate to sign .pdf documents. With help from a highly knowledgeable colleague, I've got as far as adding a certificate chain … but Acrobat is still not happy.
The details tab for the certificate highlights problems with two areas:
basic constraints CA: Yes Path Length Constraint: None
key usage Sign CRL Sign certificate (CA)
The trust tab for the certificate says nothing is allowed, and won't let me add the certificate to Trusted Identities.
How can I sort this out?
Sorry for the delay in response.
There has been some change the way certificate is used, you may visit this link: A: Changes Across Releases — Digital Signatures Guide for IT
