    • getDataToSign

      public ToBeSigned getDataToSign(DSSDocument toSignDocument, PAdESSignatureParameters parameters) throws DSSException
      Description copied from interface: DocumentSignatureService
      Retrieves the bytes of the data that need to be signed based on the toSignDocument and parameters. When toSignDocument contains an already existing signature the returned bytes are related to a new parallel signature. - Enveloped signature (XML): a new signature is added and the signed data corresponds to that pointed by the first signature; - Enveloping signature: - - XML: The parallel signature is not possible - - CMS: A new parallel signature is added - Detached signature: - - XML: The parallel signature is added - - CMS: A new parallel signature is added
      Parameters:
      toSignDocument - document to sign or the already existing signature
      parameters - set of the driving signing parameters
      Returns:
      the data to be signed
      Throws:
      DSSException
