Inspect Digital Signatures in a PDF file
Returns PDF file's digital signatures.
A document's digital signature status is computed by looking at all the digital signatures included in the document
The validity of a signature is determined by the signing certificate used to create it: If you're using a custom certificate, you need to set up Document Engine to use a corresponding certificate store in order to identify the signature as valid. Please check our guide article on how to set up custom certificates for digital signature validation.
