Good morning, this the file with the verified digest: http://www.filefactory.com/file/b3hc38g/n/signed_pdf
i still get the invalid signature error. I have no specific reason to use the filter you (Michael) mentioned, in fact i didnt even know i was using it :) I suppose that in order to use the detached one you mentioned i would have to use: PdfSignature dic1 = new PdfSignature(PdfName.ADOBE_PPKLITE, PdfName.ADBE_PKCS7_DETACHED); I was just trying this approach but adobe reader says "Signature contains incorrect, unrecognized, .... ". sample: http:// http://www.filefactory.com/file/b3hc3h9/n/signed_pdf which is, i think, because im inserting the signedHash like this: dic.put(PdfName.CONTENTS, new PdfString(signedHash).setHexWriting(true)); im trying to follow the code here: http://itextpdf.sourceforge.net/howtosign.html#signextitextsharp2 Source a few snippets: // Reason and location appearance.setReason("Very good reason"); appearance.setLocation("Great location"); appearance.setContact("Some sort of contact"); appearance.setSignDate(new GregorianCalendar()); PdfSignature dic1 = new PdfSignature(PdfName.ADOBE_PPKLITE, PdfName.ADBE_PKCS7_DETACHED); dic1.setDate(new PdfDate(appearance.getSignDate())); dic1.setName(PdfPKCS7.getSubjectFields((X509Certificate)appearance.getCertChain()[0]).getField("CN")); if (appearance.getReason() != null) dic1.setReason(appearance.getReason()); if (appearance.getLocation() != null) dic1.setLocation(appearance.getLocation()); appearance.setCryptoDictionary(dic1); int csize = 4000; HashMap<PdfName, Integer> exc = new HashMap<PdfName, Integer>(); exc.put(PdfName.CONTENTS, new Integer(csize * 2 + 2)); appearance.preClose(exc); ....digest method and signing method PdfDictionary dic = new PdfDictionary(); dic.put(PdfName.CONTENTS, new PdfString(signedHash).setHexWriting(true)); appearance.close(dic); Am i doing something wrong here?
