I Opened a document .pdf already signed by a colleague of mines with Adobe
Showing the subjected warning about the signature present on it. The user certificate signature has been generated in our internal CA.
I have added the certificate that was used to apply the digital signature into Adobe’s list of Trusted Identities by following these steps:
- Click on “Signature Panel” button on the left hand side of Adobe Reader / Acrobat
- Right click on the listed signature
- Click on “Show Signature Properties”
- Click “Show Certificate button” (under the summary tab)
- Click “Trust” tab
- Click “Add to Trusted Identities”
- Adobe Security window opens, click “OK”
- But i need to know why it is required.?
- Is there any other option available to trust the certificate Provide to the Trusted Identities inside adobe application.?
- How to resolve this on the enterprise wide to arrest this issue completely. ?
