Hello again, I did the detached method now, learned a few things on what works a little better but still gives an error (Error encountered while BER decoding:)... sample: http://www.filefactory.com/file/b3hcd3b/n/signed_pdf
Key code samples that i believe might be the reason for the errors: PdfSignatureAppearance appearance = stamp.getSignatureAppearance(); ... appearance.setCrypto(null, CcMethods.getChain(), null, PdfSignatureAppearance.SELF_SIGNED); ... PdfSignature dic1 = new PdfSignature(PdfName.ADOBE_PPKLITE, PdfName.ADBE_PKCS7_DETACHED); ... // i believe this reserves 128 bytes for the signedHash byte array int csize = 128; HashMap<PdfName, Integer> exc = new HashMap<PdfName, Integer>(); exc.put(PdfName.CONTENTS, new Integer(csize * 2 + 2)); appearance.preClose(exc); ... // regurns the signedHash (verified) byte[] signedHash = CcMethods.sign(hashDig); PdfDictionary dic = new PdfDictionary(); dic.put(PdfName.CONTENTS, new PdfString(signedHash).setHexWriting(true)); appearance.close(dic); i didnt things here like setting the name and date on the signature thats why i have all the "...". i believe im following the howtosign to the letter, but i still have errors. -- View this message in context: http://itext-general.2136553.n4.nabble.com/Another-invalid-signature-thread-tp3003710p3010293.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Many questions posted to this list can (and will) be answered with a reference to the iText book: http://www.itextpdf.com/book/ Please check the keywords list before you ask for examples: http://itextpdf.com/themes/keywords.php
