I can run the EncryptWithCertificate.java example from the book fine. However, if I change ENCRYPTION_AES_128 to ENCRYPTION_AES_256 in this example (in the two locations that it occurs), then I get: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException at java.lang.System.arraycopy(Native Method) at com.itextpdf.text.pdf.PdfEncryption.setupByEncryptionKey(PdfEncryption.java:527) at com.itextpdf.text.pdf.PdfEncryption.getEncryptionDictionary(PdfEncryption.java:633) at com.itextpdf.text.pdf.PdfWriter.setEncryption(PdfWriter.java:2057) at part3.chapter12.EncryptWithCertificate.createPdf(EncryptWithCertificate.java:73) at part3.chapter12.EncryptWithCertificate.main(EncryptWithCertificate.java:178) This behaviour was mentioned in a previous message on this list - the explanation at the time was that the AES-256 functionality wasn't implemented yet. I have installed the Unlimited Strength Jurisdiction Policy Files, and the example code installs the BouncyCastle crypto provider: Security.addProvider(new BouncyCastleProvider()); On 22 May 2012 15:23, 1T3XT BVBA &lt;info&lt; at &gt;1t3xt.info&gt; wrote: ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Use a monospaced font such as Courier: http://en.wikipedia.org/wiki/Monospaced_font Note that there are much better ways to define a layout apart from using spaces to position text.

Verification from Adobe Reader X goes just fine, reporting signature is valid but verification from iText is throwing exception. I'm using iText 5.2.1. Example of .pdf that is failing verification is attached: http://itext-general.2136553.n4.nabble.com/file/n4652242/test_sign_SHA512.pdf test_sign_SHA512.pdf Stack trace for exception is: ExceptionConverter: java.security.NoSuchAlgorithmException: SHA512 MessageDigest not available at sun.security.jca.GetInstance.getInstance(Unknown Source) at java.security.Security.getImpl(Unknown Source) at java.security.MessageDigest.getInstance(Unknown Source) at com.itextpdf.text.pdf.PdfPKCS7.(PdfPKCS7.java:564) at com.itextpdf.text.pdf.PdfPKCS7.(PdfPKCS7.java:415) at com.itextpdf.text.pdf.AcroFields.verifySignature(AcroFields.java:2307 ) at com.itextpdf.text.pdf.AcroFields.verifySignature(AcroFields.java:2257 ) at com.spica.eppl.client.controller.MainController.handleVerifyPdfSignat ure(MainController.java:137) Code for signature verification: PdfReader reader = new PdfReader(signedPdfFilePath); AcroFields af = reader.getAcroFields(); PdfPKCS7 pkcs = af.verifySignature("Racunopolagac"); //line 137 that throw exception Code used for signing: PdfReader reader = new PdfReader(srcPdf); FileOutputStream fout = new FileOutputStream(dstPdf); PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0', null, signData.isAppend()); PdfSignatureAppearance sap = stp.getSignatureAppearance(); sap.setCrypto(null, chain, crls, null); PdfSignature dic = new PdfSignature(PdfName.ADOBE_PPKLITE, PdfName.ADBE_PKCS7_DETACHED); String hashAlgorithm = signData.getEmbedSettings().getHashAlgorithm(); /* SHA1, SHA-256, SHA-384, SHA-512 */ PdfPKCS7 sgn = new PdfPKCS7(pk, chain, crls, hashAlgorithm, null, false); InputStream data = sap.getRangeStream(); MessageDigest messageDigest = MessageDigest.getInstance(hashAlgorithm); -- View this message in context: http://itext-general.2136553.n4.nabble.com/Problem-with-signature-verification-when-using-SHA2-algorithms-tp4652242.html Sent from the iText - General mailing list archive at Nabble.com.------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

You may want to adapt the example shown on p441 (listing 13.8). That example "crops" pages, meaning it makes the pages smaller. You want to do the inverse, but the same principle applies. Instead of pageDict.put(PdfName.CROPBOX, rect); with a smaller rectangle, you need: pageDict.put(PdfName.MEDIABOX, rect); pageDict.put(PdfName.CROPBOX, rect); with a bigger rectangle. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
