A digital signature field is a collection of many different objects, across several dictionaries, within the pdf file. Specifically, what parts of the digital signature field do you want to extract? For example, encrypted message digest, byte ranges, digital certificate, rectangle, appearance (there are five appearances associated with the digital signature field), title, metadata, etc.
