I was searching for a way to detect whether a pdf document is digitally signed. I noticed this reply and the mention of the possibility of doing this with PdfLoadedDocument. Could you kindly explain the steps required to verifiy that an existing document is digitally signed? Thank you and regards.

Sorry for the inconvenience,
Currently we don’t have support to detect “Adobe signatures
in existing Pdf document”, and we have added the feature request in our database,
we will implement this feature in any of our upcoming releases and we don’t have
any immediate plans to implement this feature. We usually have an interval of
atleast three months between releases. The feature implementation would also
greatly depend on the factors such as product design, code compatibility and
complexity.We will update you once the feature has been implemented.
