How to digitally sign PDF document in VC?

Hi all,
i want know how to open a PDF file and digitally sign the document programatically in vc?
Thanks

Do you mean a tool other than Adobe Acrobat or Reader? Since this is the Acrobat SDK, your users would already have Acrobat installed and can sign PDFs just fine.
What would you be adding to that?

Digitally signing pdf documents

We want to digitally sign pdf documents that are generated in the printing service / AS. (rwclient is used on the client machines to access the printing service.)
The digital sign should be on all generated pdf documents, with no intervention by the end users. The digital sign should hence be on behalf on the organisation, not the individual user issuing the pdf dokument.
In addition we would like to lock the pdf documents in order på prevent manipulation of the content.
Any surgestions on how to achieve this?
Regards

Hello,
You can create your own destination .
An example is available on OTN :
http://www.oracle.com/technology/products/reports/pluginxchange/index.html
Secure PDF Destination
This destination creates a secure PDF that is password-protected. This sample is tested with Oracle Reports 9i, Oracle Reports 10g (9.0.4), and Oracle Reports 10g Release 2 (10.1.2).

Can IXOS (OPENTEXT) handle digitally signed PDF documents

Hi All,
we have requirement where we want to store digitally signed PDF documents in IXOS (OPENTEXT) server and view them using IXOS viewer. I have tried to save one digitally sighed PDF but it was also password protected and I was not able to open it with the IXOS live link opener.
Request you to share your experience or views on this.
Thanks a lot.
Best regards,
Vithal

hi,
yes IXOS handlesDigitaly signed PDF documents,
http://opentext.com/download/livelinkdownload.html?path=/corporate/investor/secfiling/FY2005Q4_10K.pdf
Please refere tihis doc..
The repository supports queries based on metadata, full-text index and even a combination
of both. Another option is to render document content to a long-term format like TIFF or PDF. Using
digital signatures (time stamps) it can be assured that content cannot be modified without recognition.
Hence clearly say's retrival or access doc need to enter digital signature which are preconfigured during DOC creation phase.

How do I sign PDF documents on the MS Surface Pro

How do I sign PDF documents on the MS Surface Pro

I am not sure exactly what you did and what did not work.
But you can ask question on the Acrobat's Security & Electronic Signatures forum to get help from the Acrobat experts.

The detailed description of the problem and screen shots would be helpful to get answers.

How to digitally sign pdf file

Hi,
I am working on Java and Digital Signature and new to this field. I want to sign a pdf file using smart card. I have tried signing xml files and it's now running fine. The signature is attached with the xml file. Similarly I want to sign a pdf file and the signature should be attached with it.
Please help me to do that.
Thanks in advance.

Thnx.
Any way I could manage the matter.
I hope my code may help people working on same.
So the code is here
static String fname = "D:\\file.pdf";
static String fnameS = "D:\\file_signed.pdf";
//The main method
public static void main(String[] args) {
        try {
            this.signPdf() ;
        } catch (Exception e) {
            System.out.println(e);
//The signer method
public static final boolean signPdf()
            throws IOException, DocumentException, Exception {
        String fileKey = "D:\\MyCertificate.pfx";
        String fileKeyPassword = "password";
        try {
            KeyStore ks = KeyStore.getInstance("pkcs12");
            ks.load(new FileInputStream(fileKey), fileKeyPassword.toCharArray());
            String alias = (String) ks.aliases().nextElement();
            PrivateKey key = (PrivateKey) ks.getKey(alias, fileKeyPassword.toCharArray());
            Certificate[] chain = ks.getCertificateChain(alias);
            PdfReader pdfReader = new PdfReader((new File(fname)).getAbsolutePath());
            File outputFile = new File(fnameS);
            PdfStamper pdfStamper;
            pdfStamper = PdfStamper.createSignature(pdfReader, null, '\0', outputFile);
            PdfSignatureAppearance sap = pdfStamper.getSignatureAppearance();

I need to digital sign a document using Acrobat Reader. Is it possibile?

I am an IT Manager for a little city in northern italy.
I have almost 50 clients with smart cards enabled for what concerns digital signage.
I use flawlessy the software of the firm who provides the smart card. (infocamere.it).
This uses sha256 crypt, no problems about it.
The problem I have is:
The final file is a "p7m" envelope.
I would prefer to use a "pdf" envelope. One only file.
I tried to follow this video
http://tv.adobe.com/watch/acrobat-x/how-to-digitally-sign-a-document-with-adobe-reader/
Simply it doesn't work.
I have also a couple of Acrobat Standard.
I can "pdf-sign" with Acrobat Standard 9.
I am not able to do the same with reader 9 or X.
There is a way to do it?
Thank You.

You can sign a PDF using Adobe Reader 9 or X, but the document must be "Reader Extended" to enable this functionality, This can be done using ADEP\LiveCycle Reader Extensions (server product) or Acrobat Professional 9 (Advanced > Extend Features in Adobe Reader) or Acrobat X Professional (File > Save As > Reader extended PDF)

How to digitally sign a form or PDF?

We currently have a process in place that tracks all of our deliverables and notifies our government clients when we have invoiced them. We email them a message to let them know an invoice is ready to be approved. They login to our site via a browser, view the invoice, and approve or disapprove it. If approved a PDF of the invoice is created via ColdFusion and is sent to them.
There may be an upcoming requirement to have the client digitally sign the document. This is where the fog begins. How best to do this? Assuming that each client will have a PKI ID (and that's a big assumption), how do they sign the document? I know they can open the PDF and sign it, and then I can setup a ColdFusion-based form to allow them to upload it back to us, but is there any other way?

We use RightSignature.com; it works great and our customers like it. DocuSign.com has been trying to get our business as well. The advantage of DocuSign over RightSignature is that everything can be signed without the user leaving our site whereas RightSignature sends the user an email with a link to sign and then sends us the final signed document. Since we're not using DocuSign, I'm not sure if there are other pros and cons.

How to automate digital signing PDF Files in batch

I am trying to find a way to automate as much as possible the placing of a digital signature on a set of PDF documents. We have Adobe Acrobat Pro 8.1 and the machine has MS Office 2003 with Vista Business. Here's a scenario: A set of documents exist in a TO-BE-SIGNED folder, each unsigned. The user uses MS Access 2003 form with a button with VBA code to open and show the first document in the folder. The AcroExch.App, AcroExch.AVDoc, and AcroApp.Show APIs are used to do this. I found code on the internet to do that. Rather than having my client now have to go through all the manual steps to place a digital signature on the document, I want to streamline it to a single click if possible. Right now he has to click Advanced > Sign and Certify > Place Signature > then click and drag > then enter his password > then click sign > then save and close the doc. Can all this be automated? An added bonus would be automatically saving or moving the signed doc to a different folder when it is signed.
I have created a stamp that allows me to add a stamp with just two clicks. Can such be done to add a digital signature? Is it possible to add a button to the toolbar to do this? Can it be done in Access VBA using some Acrobat API calls? Another feature I want to include is moving quickly from one document to the next in the TO-BE-SIGNED folder. Like the arrow buttons take you from page to page, can a button be added to the Acrobat toolbar to take you from doc to doc in a particular folder? Or can that be done using VBA and some Acrobat API calls? To maintain the security of the password protection and yet cut down on clicks and keystrokes, I would like to input the password just once at the beginning of the session and have it remembered or applied to all the docs that get signed as long as that session is open.
I've found some software that purports to do much of the above, but they are all very expensive and assume a big business with big bucks. If anyone knows of inexpensive software that will REALLY do this, I'm open to that as well, though I'd like to control the process myself if possible. I consider myself a beginner with Acrobat and using API calls and would appreciate any help anyone can give. Is the above clear and even possible?
PS: I'm new to this site and using SDK. I posted this under Security (thinking digital signatures) and was asked to post it here, which I'm glad to do.
Thanks much!

Our workflow is such that on infrequent occasions, we have a digitally signed PDF file and the doctor wants to append a scanned note to it. In the past, we could do this, but not now. In the past, when we added the scanned doc, we received a message saying that the doc is already signed and asking if we want to overrwrite the doc. If we respond Yes, then Acrobat would allow it and the signature would indicate that the original part of the document was not modified, but that something had been changed--namely, a doc had been appended. The signature indicated that something had changed since it was added, but it still allowed the append. The signature would have an exclamation point in a yellow triangle indicating the doc had been updated since signed. For our purposes, that was okay because we know what the change is based on the original doc and we know what is appended. Now, however, we cannot append at all. The only thing that is different that I know of is that the doc was signed with software that is not Adobe Acrobat, even though the other software uses an Adobe Acrobat self-created digital signature.
I hope I've explained that clearly enough.
Thanks for your help.

In Acrobat XI, how can we have more than 2 people digitally sign a document or template?.

The document is a PDF template with 2 signature fields for approval. When the first person digital signs the document it shows the GREEN tick that it's signed and all signatures are valid. Then it gets emailed for the second person to digitally sign and ofcourse, the document becomes invalid. (We don't want to use the echoSign cloud service and there is no Acrobat server setup). Can someone share the light please?

A PDF Form Template will try an execute an action to create a new page based on the template page. This action will break the first signature because it changes the document by adding a new page after it has been signed. Is it imperative that the document be a PDF Form Template? If all that is called for is two signatures then create the document with two signature fields and without it being a PDF Form Template.

How can I convert digitally signed PDF's so I can combine them into a single multi-page PDF?

We are an architectural firm and we receive drawings from consultants as PDF's that are digitally signed. In order to combine all of our drawings into a single PDF, we currently send the PDF's to a printer, have them printed, and scan them as new PDF's. This process reduces the clarity of the PDF and re-printing the scanned PDF's reduces the clarity even further. Is there a way to "flatten" or otherwise convert the digitally signed PDF's so we can combine them into a single multi-page PDF? Making a portfolio is not an option. We need an actual multi-page PDF for a variety of reasons. This problem is actually preventing our office from using digital signatures so any help would be greatly appreciated.

You can't. There was a discussion on this Forum a few months ago on this subject. Look it up for more info.

Hi 2014 nurse pracitioner,
Let's see what we can figure out! What happens when you try to sign your documents? Are you receiving an error message when you try to sign? When you open a file in Reader, do you see Sign in the upper-right corner, as shown below:
I look forward to hearing back from you.

Digitally Signed PDF crashes Mail and Preview

I've run into an odd situation - if I try to send a digitally signed PDF file using the Mail app or even view that file in the Preview app, those apps crash. The PDF files are created in Adobe Acrobat Pro version 9.1.0 (for the Mac). My Mail and Preview apps are right up to date.
The same PDF file still opens just fine in Adobe Acrobat. If I create exactly the same file, but don't go through the digital signature step, the files open (in Preview) and send (in Mail) just fine.
Anyone else run into this problem and/or have a suggestion on how to avoid it?
(P.S. By "create", I mean I have printed to the "Adobe PDF 9.0" print driver, which creates the base PDF file. Then I have also "secured" the file by requiring a password be entered to change anything. The final step, which seems to be causing the problem, is digitally signing the file.)

The problem may be related to asking Acrobat 9 to output a file format "compatible" with older versions -- along with adding security.
If you check the Console log, I think you will find that the "mdworker" task is also crashing -- even when you open the file successfully with Adobe Reader. I presume this is Spotlight trying to index the file.
Safari will also crash when attempting to view such a PDF. It puts out a Console message indicating invalid AES block size or some such. Presumably this is related to the 128 bit AES security in the PDF file. Using 128 bit RC4 results in a file that doesn't crash Preview, but the document content is garbled by Preview so it's just as bad.

How do you sign your document

How do you sign a document in adobe

A 'pen and ink' signature drawn using the comment tools is just a graphic, anyone can copy and reuse it. A commercially-issued digital ID used in a signing/certifying process is verifiable and cannot be extracted from the PDF, nor can the PDF be altered without breaking the signature. Self-signed IDs created in Acrobat cannot be extracted, but have no external validity - anyone could fake one.
