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.

Where should the Green Tick get displayed in digitally signed pdf files in whom the Signature has been validated ?

I have Windows 7 & Adobe 11 installed on my P.C (Apart from other Software) . Recently I downloaded Digitally Signed .pdf files & validated the Signature with Trust Certificates . However , the Green Tick Mark is coming on the left-hand side of a blue panel situated in-between the menu bar & the document . Shouldn't it be coming at the bottom right side of the document (Just above the name of the signatory) ? Is there anyway I can get the green tick to display at the bottom right side of the document or is this just the way the green tick gets displayed in current versions of adobe reader ?
This is the way it gets displayed on the top - left portion of the screen :
However , it does not get displayed in the below manner :

First of all, you need an app on the iPad that can read those files that you want to transfer. Adobe Reader and iBooks are two free apps that will read PDF files. Adobe Reader is much more robust than iBooks as it offers so many more features like renaming files, creating folders, annotating, highlights, etc.
Download Adobe Reader in the App Store. Then read this about file sharing with iTunes.
iOS: About File Sharing - Support - Apple
There are other ways to get files to the iPad, like email, DropBox and some other apps that let you mount your iPad like a flash drive.
This should be helpful as well.

How do I digitally sign projector files?

I am currently selling apps in Flash projector .exe format. How can I install a certificate from Verisign or Thawte?
Roger

I want to access the file system of the client using a
servlet which shall be digitally signed.
You cannot do this. It is technically impossible. You are referring to an Applet. There are two ways to get the Applet to read the files of the client system.
1. Have the client open up security by editing the java.policy file, which is dangerous.
2. Digitally Sign the Applet.
How do I do it.Please send the code.
Write the code yourself. Sorry to say, but nobody here is going to program your code for you. That is, unless you pay them money!

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();

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.

Can I open reader and digitally sign pdf in flash?

First off let me say, I have 0 experience with Adobe Flash or Adobe Air, so this may be a dumb question or I may not even be asking in the right place. I currently have an application which uses Adobe Reader to digitally sign PDF files. The PDFs are displayed inline within a webpage. The user must use Adobe Reader because it needs to be FIPS 140 certified. The issue we are running into is with browsers like Chrome and Firefox bunding their own PDF reader, it brakes our application. I am looking for a way to force users to use Adobe Reader. From reading on the web, it looks like this isn't really possible and we are at the mercy of the PDF plugin the user has installed. The idea I thought of, though, would be to write an Adobe Flash application which would display the PDF. I am hoping doing it this way, I could force the use of Adobe Reader and not the PDF plugin of the browser. Does anyone know if this will work? And if it does, will I have all functions of Adobe Reader available (specifically digitally signing)?

for a web based app, you can't easily display a pdf in flash. even for an air app (or any other platform), you can't force anyone to use adobe reader (especially, because not everyone has adobe reader).

Creating a visible signature on multiple pages when digitally signing a PDF

When I digitally sign a PDF file, is there a way to make the visible signature appear on every page of the PDF at once, instead of just the current page? Specifically, I'd like to place a scan of a professional engineer's seal on every sheet of a PDF containing MEP drawings, in one step, as I digitally sign the file with Adobe Acrobat. I've done some research and haven't found any relevant information for this particular question, so maybe it's not possible? I'd like to know for sure, one way or the other.
Thanks much.
Robert

The appearance of a signature is something of no importance at all, so just stamp the pages first, then sign withou an appearance.

How to remove password-encryption in a signed PDF file?

I can open a password-encryption and digitally signed PDF file using Acrobat X Standard but cannot remove the password protection.
Can anyone help me remove the password encryption? The Acrobat only allows to set passsord encryption before adding digital signature to a PDF file. Can I sign a PDF file and then encrypt it with password? Thanks.

Removing the security, if it is possible, would destroy the signature.
Encrypting a signed PDF would destroy the signature.
This is because signatures validate the file exactly as it is, and changes to the file break the signature by design. Setting security is a change to the PDF (a big change).

Digital Signature Data File Issue

Hello all,
I am something of a network administrator / supervisor (by position not education so some of the technical aspects of my shop still alude me). Right now I am having an issue with digitally signing PDF files; previously when I signed the files the size would remain approximately the same (moving perhaps from 200 KB to 300 KB, however when I sign files now the size jumps to almost 7000 KB. Previously I had received a message when signing that indicated I could change a setting to add an extra layer of protection and my hypothesis is that this may be the cause, but I am not 100% sure of that.
Has anyone experienced this problem before, or have any possible solutions? My guess is that there is an option where Adobe controls how secure the signature I create has to be and it defaulted to the more secure, much larger file size after I received the initial notification.
Thank you for your guidance and wisdom.

Is it possible to digitally sign a jar file that will be used to install CF in WebSphere?

I am currently working for a contractor for the DoD. We are maintaining a project that uses CF installed as an application through WebSphere. We are currently going through a security checklist and being asked to provide evidence that the CF application has a digital signature. From what we can gather they are looking to see that the jar file installed into WebSphere is digitally signed. We have reached out to IBM, and have received a response that digital signatures are recognized by WebSphere.
Unfortunately, it seems that those that are looking for the evidence do not know much more than what the checklist requirement states. They cannot provide more details or expand on what they need. Any assistance or advice in this matter would be appreciated.
Thanks,

So as I understand this, it means the end-user has no way to know it was me that truly signed it. But relies on their common sense I suppose.
That is correct. The CA has verified, and is certifying, that you are who you claim to be. If you or I use a 'self signed' certificate, it does not carry the same level of trust. As you might understand already, the dialogs are different between the two certificate types, and some users cannot accept trusted code from an unverified (self-signed) certificate.
I have been meaning to write a page on the differences between the two certificates. It is well worth looking into getting a cert. from a CA.
There was a stage when one of the major CAs were offering 'freemail' certificates that came emblazoned not with your name, but 'free mail' itself. I did not like them because of that, and continue to use a self-signed certificate.

Cannot save file after it is digitally signed

Hello, I work for the IT Dept at my company and one of our employees is having trouble saving PDF files after digitally signing them. He received the error message:
The document could not be saved. Can not save to this file name. Please save the document with a different name or in a different folder.
After each signature, Acrobat asks to save the file, which he does. The strange thing is that he may sign the same document 4 times, and the error might only occur on the last attempt to save. It will successfully perform it the first three times. I cannot find a pattern to the errors. The times he gets the error messages don't necessarily all happen on the last attempt, it might be the first or the middle. I have tried updating the program and searching around through the options to find any setting which may be applicable, but have had no luck. I have been trying to solve this problem for a few days now and I can't make any progress.
Does anyone eles have this problem or have a solution?

I don't have an answer as I have never seen the problem. However, for those that might be able to answer the question they will likely want to replicate the problem. It would be helpful to know what OS (and if 32 or 64-bit) and what version (include subversion) of Acrobat -- latest 10.1.4. If you can create a sample document that has the problem, then folks may have an easier time to repeat it. A document can be posted either at one of your sites, Acrobat.com, or maybe dropbox.

Include many jars for a complex signed applet in html file??

hello
I'd like to know how it's possible to put a signed applet in an html file, that needs many jar files.
I explain myself: I know that to create a signed applet and to put it in an html file, I need to create a Jar file that contains this applet, create a private key with keytool, sign the jar and include it in my html file with the tag <applet code="....." archive="......jar".... />
This works fine if my applet is a simple program that only uses the clases present by default in the jdk.
In my case, I have a big project, with many packages. In one of these packages, I have my applet that uses some classes of the other packages, which use classes from imported jars, such as BouncyCastle, and others...
There is still no problem when I run the applet from the applet viewer.
The problem appears when I put the JAR file with all these classes in the html file: there is a problem since it doesn't know anything of these classes imported from these jars.. It's quite obvious actually.
My question is: how do I do to make the html file aware of these classes? Is there an html tag that allows us to include many jar files? Do I have to decompress all these jars, take all the directories, add them to the directories of my project and create a BIG jar (that's what I did, but it's really dirty, and heavy! (11M))??
Does anyone have an idea about how I can do it?
Thanks for your help
Philippe

11 MB is pretty big for an applet.
Let's say your applet uses java 3d, normally a client would download and
install this seporately, meaning the jars needed end up in lib/ext directory where
any applet can find them.
Check what applets need to be installed (put in lib/ext) and what can be
downloaded:
<object .....
<param name="archive" value="myJar.jar, myOtherjar.jar" />
