# Although the steps above describes extending the SignatureHandler class, this sample demonstrates the use of # StdSignatureHandler (a built-in SignatureHandler in PDFNet) to sign a PDF file. This can be used to # add additional information to the signature dictionary (e.g. For example, UseSignatureHandler() returns an instance # of SDF dictionary which represents the signature dictionary (or the /V entry of the form field). # Additional processing can be done before document is signed. # IMPORTANT: If there are already signed/certified digital signature(s) in the document, you must save incrementally # so as to not invalidate the other signature(s). This will also create the digital signature dictionary and write a cryptographic signature to it. # NOTE: It is only possible to sign/certify one signature per call to the Save function. # iii)Ĝall SignOnNextSaveWithCustomHandler/CertifyOnNextSaveWithCustomHandler with the SignatureHandlerId. # ii) Create an instance of the implemented SignatureHandler and register it with PDFDoc with # pdfdoc.AddSignatureHandler(). The SignatureHandler will be used to add or # validate/check a digital signature. This overload is to be used # in the following fashion: # i) Extend and implement a new SignatureHandler. Taking a unique identifier of a signature handler registered with the PDFDoc.
