Python

public void SignDocument( 
   string destinationFileName, 
   string signatureFileName, 
   string signaturePassword 
)

public:  
   void SignDocument( 
      String^ destinationFileName, 
      String^ signatureFileName, 
      String^ signaturePassword 
   )

def SignDocument(self,destinationFileName,signatureFileName,signaturePassword):

destinationFileName

Name of the PDF file to be signed, the PDF document must be valid and exist.

signatureFileName

Name of the file containing the digital signature. This should be a valid PFX file and cannot be null.

signaturePassword

The password to use if the PFX file requires one. Otherwise, null.

SignDocument will add the PFX digital signature in signatureFileName to an existing PDF file. Use ParsePages with the PDFParsePagesOptions.Signatures to read the digital signatures associated with a PDF document.

The application must ensure that digital signature is supported using PDFDocument.GetDigitalSignatureSupportStatus.
