Instead of specifying a custom image file to fit into the digital signature form field, is there a way to generate the type of default Acrobat Digital Signature image generated by Acrobat digital signature? ]]> Wed, 03 Oct 2018 21:30:07 +0000 http://www.quickpdf.org/forum/visible-digital-signature_topic2563_post14372.html#14372 <![CDATA[Visible digital signature : Thank you for your reply.I was...]]> http://www.quickpdf.org/forum/visible-digital-signature_topic2563_post12610.html#12610 Author: tfrancois

Thank you for your reply.

I was able to solve the issue.  The PFX file was saved in the Computer's Personal certificate store so I had to use the SetSignProcessKeyset to 2 - Crypt Machine Keyset instead of leaving the default 1 - Crypt User Keyset set.

Once I made that change, it worked perfectly.  Hope this helps someone else.

This thread was about showing a visible signature block when a PDF is digitally signed.  If you are getting an error indicating an invalid password, that is something different: if the signature cannot be loaded, it clearly cannot be applied, with or without a visible presence.  Please show your actual code and the exact error return that you get, and someone may be able to help.

Hello,

I am having the same issue with the incorrect password with a valid PFX and password.  What did you do to solve this issue?   I am at a complete loss.   I am considering purchasing the product, but with no indication that its working it may not make sense to make the investment.

Thanks,

Teddy.

Hi Guys,

The result returned by EndSignProcessToFile will always be zero. To check the result of the digital signature signing process call the GetSignProcessResult function.

The documentation has been updated to reflect this and the change will be in Debenu Quick PDF Library 10.12 Beta 2.

Cheers,
- Rowan.

In my testing (of 9.14b4), the (undocumented) return code from the EndSignProcessToFile function is always zero whether or not the signature is valid, though no file is written if not.  I have a support ticket open and I know Debenu are working on the signatures for 9.14.  You do not need the SignFile as well as the EndSignProcessToFile.]]> Sun, 28 Apr 2013 11:15:19 +0000 http://www.quickpdf.org/forum/visible-digital-signature_topic2563_post10774.html#10774 <![CDATA[Visible digital signature : Hi, I&#039;m having troubles getting...]]> http://www.quickpdf.org/forum/visible-digital-signature_topic2563_post10773.html#10773 Author: Chumly

Hi,
I'm having troubles getting this to work in asp using the ActiveX module...
Result all come back as '1' until the EndSignProcessToFile which returns '0'. But that does not tell me why.

Using the second method, (SignFile) it returns '7' which says it has the wrong password.
However, the same data works fine using jSignPDF.
Can you help me understand what the requirements of the pfx file is that will allow me to get rid of jsignpdf?
Code in use:
     SigProcID = QP.NewSignProcessFromFile(FilePath,OpenPassword)
     result = QP.SetSignProcessInfo(SigProcID,Reason,Location,ContactInfo)
     response.write "Result: "& result & "<br>" & vbCrLf
     result = QP.SetSignProcessField(SigProcID,"DigitalSignature")
     response.write "Result: "& result & "<br>" & vbCrLf
     result = QP.SetSignProcessFieldBounds(SigProcID, 100, 600, 200, 100)
     response.write "Result: "& result & "<br>" & vbCrLf
    result = QP.SetSignProcessFieldImageFromFile(SigProcID, SigImageFile, 0)
     response.write "Result: "& result & "<br>" & vbCrLf
     result = QP.SetSignProcessPFXFromFile(SigProcID,PFXFileName,PFXPassword)
     response.write "Result: "& result & "<br>" & vbCrLf
     result = QP.EndSignProcessToFile(SigProcID, OutputFileName)
     response.write "Result: "& result & ", Path: " & OutputFileName & "<br>" & vbCrLf

     result = QP.SignFile(FilePath, "", SignaturesFieldName, OutputFileName, PFXFileName, PFXPassword, Reason, Location, ContactInfo)
     response.write "Result: "& result & ", Path: " & OutPutFileName & "<br>" & vbCrLf


Output:
Saved: c:\inetpub\wwwroot\test\1367103662.pdf
Result: 1
Result: 1
Result: 1
Result: 1
Result: 1
Result: 0, Path: c:\inetpub\wwwroot\test\1367103662-signed.pdf

Hi Guys,

Debenu Quick PDF Library 9.14 Beta 1 has been released and can be downloaded from the Debenu Blog.

Here is some Delphi sample code that demonstrates how to use the new visual digital signature feature:

------------------------------------------------
procedure TForm7.btnNewSignProcessFromFileClick(Sender: TObject);
var
SignProcessID: Integer;
begin
    DPL := TDebenuPDFLibrary0914.Create;
    if DPL.UnlockKey('..license_key_goes_here') = 1 then
    begin
      DPL.DrawText(100, 700, 'This is the file to be signed');
      DPL.SaveToFile('TheUnsignedFile.pdf');

      SignProcessID := DPL.NewSignProcessFromFile('TheUnsignedFile.pdf', '');
      if (SignProcessID > 0) then
      begin
        DPL.SetSignProcessPFXFromFile(SignProcessID, 'qpl_test.pfx', 'testing');
        DPL.SetSignProcessInfo(SignProcessID, 'To test digital signatures', 'The World', 'Contact me');
        DPL.SetSignProcessField(SignProcessID, 'Contract Signature');
        DPL.SetSignProcessFieldBounds(SignProcessID, 100, 600, 200, 100);
        DPL.SetSignProcessFieldImageFromFile(SignProcessID, 'visualsignature.jpg', 0);
        DPL.EndSignProcessToFile(SignProcessID, 'TheSignedFile.pdf');
      end;
    end;
end;
------------------------------------------------

If you experience any issues with this please let us know.

Cheers,
- Rowan.

struhadlo and tfrost,

Debenu Quick PDF Library 9.14 will include two new functions:
SetSignProcessFieldImageFromFile
SetSignProcessFieldBounds

These will allow the creation of a digital signature with an appearance stream containing the specified image.

Look out for the first beta of 9.14 due out soon.

-Kevin
