Ais a certificate issued by a trusted certificate authority (CA). In the SSL ecosystem, anyone can generate a signing key and sign a new certificate with that signature. However, that certificate is not considered valid unless it has been directly or indirectly signed by a trusted CA.
A trusted certificate authority is an entity that has been entitled to verify that someone is effectively who they declare themselves to be. All operating systems, including Windows, and most web browsers ship with a set of trusted CAs.
Not surprisingly, root certificates get updated over time, which can impact your signature certification process if, say, you don’t have one.
To solve this issue, you can have PDF editor PhantomPDF trust all root certificates in the Windows Certificate Store to speed-up your signature verification process.
To do so, follow these steps:
- Go to the File Tab
- Select Preferences
- Open the Signatures area
- Under Signing & Verification select Change Settings
- Check the first two Options
- Check the two options under Windows Integration
- Click OK
