Several questions about SignatureField and Signature

Hi,


I have several questions in the process of learning Aspose Library.

First is, in a PDF, we would probably have a certificate chain, that means we can have more than one certificate. But our SignatureField.ExtractCertificate() can only have one stream as return value. so how can we got multiple certificates from it?

Second is, is the return value Signature.Verify() Method verify all the certificates is correct?

Thanks a lot

Hi Arashi,


Thanks for your inquiry. As per my assumption, one signature field should use a single certificate. So the subjected methods return that specific signature field information.

However, we will appreciate it if you please share a sample document that have a certificate chain(more than on certificate). So we will look into it and provide you information accordingly.

Best Regards,
