  • How to Digitally sign a PDF report/Mail automatically?

    Hi experts!
    I have cron'ed shell script that runs a report (Oracle Reports 6i) and the output the report is a PDF document which i send it as an attachment to a mail recipient on my MS. Exchange server.
    This is working fine!
    Now, i wish to digitally sign either the message or the PDF document it with a Digital Certificate (from Verisign).
    Can you please guide me on how this can be done? Should I do it at the Database level, Application server level or the OS level (sendmail)
    [Assume i already have already received my certificate from Verisign]
    Thank you in advance for your precious time and replies.
    Best Regards
    Yogeeraj

  • Digitally sign multiple pdf files

    How to digitally sign multiple pdf files with adobe acrobat XI?

    Are you trying to apply certificate-based encryption or add a signature to a PDF form field?
    The first one is easy with Acrobat Pro; just create a new Action with the encryption task set to your requirements, then run the Action against a folder of files.

  • How to digitally sign PDF document in VB?

    Hi,
    I was wondering if there was a way to open a PDF file and digitally sign the document (with the electronic signature info showing on the bottom of the last page) programatically?
    Thanks

    > (1) When I download the SDK, it only has a setup file which I launch - I don't see any documentation in there and no menu item is created.
    Where did you download the SDK?
    > (2) When I go to the livedocs.abobe.com link and look how to use Javascript to digitally sign documents, the link is blank and is waiting for someone to post a comment.
    May be a problem of your browser.
    > Does someone know of a VB code that allows you to digitally sign the PDF documents via Javascript?
    Look at the JavaScript sample AddSignature in the SDK.

    Hi robertb48724220,
    Are you using the same email address that you use here in the forums? That's how I looked up your account, and saw that you have a active subscription. You should be able to sign in with that email address and the associated password.

  • 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 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 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?

  • How do you auto populate a date in a different text field after someone digitally signs the PDF form?

    I am trying to auto populate a date in a text box on the upper right hand corner of my document after someone digitally signs it. Is this possible? How do you do this?

    Go to the Properties of the Digital Signature field and under the Signed tab enter this JS code, under the last option:
    this.getField("SignDate").value = util.printd("mm/dd/yyyy", new Date());
    this.getField("SignDate").defaultValue =this.getField("SignDate").valueAsString;
    Of course, you can adjust the field name and the date format used in the script above.

  • 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();
                //sap.setCrypto(key, chain, null, PdfSignatureAppearance.SELF_SIGNED);
                sap.setCrypto(key, chain, null, PdfSignatureAppearance.VERISIGN_SIGNED);
                sap.setReason("Security");
                sap.setLocation("Kolkata, India");
                sap.setSignDate(Calendar.getInstance());
                sap.setVisibleSignature(new Rectangle(10, 10, 50, 30), pdfReader.getNumberOfPages(), "Subhadip Pramanik");
                pdfStamper.setFormFlattening(true);
                pdfStamper.close();
                return true;

  • How can I digitally sign a pdf document and also disallow changes to the document?

    When I digitally sign the document it does not let me lock it down - when I lock down the doc first, it does not allow for digital signature. Please help.

    The initial document should have its properties set as:
    Changing the Document: Not allowed
    Signing: Allowed
    That way no one can make changes to it but anyone may sign it. These properties are available in v9, but I'm not sure about previous versions.

  • Digitally Signing a PDF using Adobe Reader

    Hi,
    I am trying to create a PDF with a digital signature form so that any of our users with Adobe Reader can digitally sign (to authorise) the document.
    I am using Acrobat 9 Standard, I have created the signature form and saved with "Extend Forms Fill-in & Save in Adobe Reader..." This works fine for other forms (tick box for example) but not the Signature field. The field is viewable but all options are greyed out.
    The security settings prior to saving "Extend Forms Fill-in & Save in Adobe Reader..." are all allowed, but after Changing the Document/Document Assembly/Commenting/Signing/Creation of Template Pages are all Not Allowed. I appreciatesome need to be restricted to allow for extended features to work in Adobe Reader but the link below implies (unless I am missing something) that signing should be possible in Adobe Reader:
    http://help.adobe.com/en_US/Reader/8.0/help.html?content=WS58a04a822e3e50102bd615109794195 ff-7d48.html
    Am I missing something, or does this just not work?
    Thanks in advance

    Thanks for the information. I am now trying using a trial of Acrobat X.
    However I am having the same issue now I can't even tick the checkbox. When the PDF is opened with Reader on the same PC it works as expected (both checkbox and signature field are available). Soon as it is emailed/moved somewhere else we can't even tick the checkbox with the message below coming up on opening:
    "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contrct the author of the orginal version of this document"
    I've also tried using Distribute through Acrobat but receive the same message.
    So I am struggling with creating a PDF on one PC that needs to be digitally authorised by someone else on a different PC, using Adobe Reader.
    I have been using Save as...>Reader Extended PDF as the Advanced menu is no longer there...
    Apologies if this something obvious and simple, this is the first time I have tried to do this.

  • Digital signed and PDF byte-serving

    Is a PDF that has been created/enabled for 'fast web view' and then been subsequently digitally signed, still able to use byte-serving optimization or does the fact that the entire PDF needs to be available for sig validation preclude that type of fast web view optimization?

    The entire PDF needs to be downloaded for signature validation to work.

  • How to digitally sign a doc??

    Hi ,
    After generating digital signature is it appended to the doc?? If so then, how images and audio data are signed?? Can they be signed the same way as other text docs are signed??
    Jahnvi

    It depends on what "transport" mechanism you plan on using. If you choose to use PKIX standards, then a PKCS7 object gives you the structure for transporting the contents along with its signature. If you prefer to use "modern" web standards, then the W3C's XMLSignature standard gives you the structure you need for transporting content and signature. (I prefer XMLSignature for new applications).
    Yes, any object - text or binary - can be digitally signed and transported using either of these standards.

  • How to digitally signed the driver

    Hi all ,
    i am using windows server 2012 evaluation version , i am trying to install the driver for pnp network adapter device , unfortunately i am getting the error saying driver detected but not digitally signed , so anyone can tell me what could be the possible
    way to fix the issue.
    -Vikram

    A signed driver is a device driver that includes a digital signature. A digital signature is an electronic security mark that can indicate the publisher of the software.
    If a driver has been signed by a publisher that has verified its identity with a certification authority, you can be confident that the driver actually comes from that publisher and hasn't been altered.
    In your case please download the driver from the vendors website and install it.
