    You should be able to do this with iText. Here's a snippet of the code that will sign the PDF<br />
    <br />
    <pre class='_prettyXprint _lang-auto _linenums:0'>
    KeyStore ks = KeyStore.getInstance("pkcs12");
    ks.load(new FileInputStream("my_private_key.pfx"), "my_password".toCharArray());
    String alias = (String)ks.aliases().nextElement();
    PrivateKey key = (PrivateKey)ks.getKey(alias, "my_password".toCharArray());
    Certificate[] chain = ks.getCertificateChain(alias);
    PdfReader reader = new PdfReader("original.pdf");
    FileOutputStream fout = new FileOutputStream("signed.pdf");
    PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
    PdfSignatureAppearance sap = stp.getSignatureAppearance();
    sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
    sap.setReason("I'm the author");
    sap.setLocation("Lisbon");
    // comment next line to have an invisible signature
    sap.setVisibleSignature(new Rectangle(100, 100, 200, 200), 1, null);
    stp.close();
    </pre>
    <br />
    There appears to be a lot of good information <a class='bbc_url' href='http://itextpdf.sourceforge.net/howtosign.html'>at this sourceforge page</a>

    Sorry I could not understand what is iText, is it a software to use with BIRT? Where should I insert this code?

    If you can send me the steps showing how to configure the report for this purpose.

    Thank you very much for your help.

    iText is a library that allows you to create and manipulate PDF documents. With BIRT you create your report (PDF) so after that you can use iText to attach a digital signature, downlaod the JAR from <a class='bbc_url' href='http://itextpdf.com/'>http://itextpdf.com/</a&gt; and add to your project ;)

    Hello,

    I included the JAR libraries in BIRT, still have to insert the below code, where should I insert it??

    KeyStore ks = KeyStore.getInstance("pkcs12");
    ks.load(new FileInputStream("my_private_key.pfx"), "my_password".toCharArray());
    String alias = (String)ks.aliases().nextElement();
    PrivateKey key = (PrivateKey)ks.getKey(alias, "my_password".toCharArray());
    Certificate[] chain = ks.getCertificateChain(alias);
    PdfReader reader = new PdfReader("original.pdf");
    FileOutputStream fout = new FileOutputStream("signed.pdf");
    PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
    PdfSignatureAppearance sap = stp.getSignatureAppearance();
    sap.setCrypto(key, chain, null, PdfSignatureAppearance.WINCER_SIGNED);
    sap.setReason("I'm the author");
    sap.setLocation("Lisbon");
    // comment next line to have an invisible signature
    sap.setVisibleSignature(new Rectangle(100, 100, 200, 200), 1, null);
    stp.close();

    Thank you very much for your kind help!

    I have added the jar files in BIRT and I inserted the code in initialize, but I couldn't!<br />
    <br />
    It says that there is a ';' missing. Please check the attached screenshot.<br />
    <br />
    Plus I couldn't find what should be the instance (first line)<br />
    <br />
    <br />
    Any help for this?
