Hi, sounds like an interesting problem ! We are running a verification service ( http://sig-check.eu/ ) using iText, but the crypto-part is done by the iaik crypto provider.
Could you please send your strange document ?

I'm trying to download older versions of Bouncy Castle to see if they will work with iText 2.0 and up but their ftp site isn't letting me get to previous releases. Anyone know of another site for getting older versions of Bouncy Castle or changes I need to make to get the code to work with the latest versions Bouncy Castle and iText? 021336 wrote: > > Using the standard code below: > > PdfReader mReader = new PdfReader(aUnsignedFileName); > AcroFields mForm = mReader.getAcroFields(); > ArrayList mSignatures = mForm.getSignatureNames(); > String mName; > for (Iterator i = mSignatures.iterator(); i.hasNext();) > { > mName = (String)i.next(); > System.out.println(mName); > PdfPKCS7 pk = mForm.verifySignature(mName); > > I am getting a Bouncy Castle error when executing "verifySignature" > > java.lang.NoSuchMethodError: void > org.bouncycastle.asn1.ASN1InputStream.<init>(java.io.InputStream, int) > > at > org.bouncycastle.jce.provider.X509CertParser.readDERCertificate(Unknown > Source) > > at org.bouncycastle.jce.provider.X509CertParser.engineRead(Unknown > Source) > > at org.bouncycastle.jce.provider.X509CertParser.engineReadAll(Unknown > Source) > > at com.lowagie.text.pdf.PdfPKCS7.<init>(Unknown Source) > > at com.lowagie.text.pdf.AcroFields.verifySignature(Unknown Source) > > Anyone have any suggestions? > > I am using Java 1.4, iText 2.1.2, and BouncyCastle libraries 1.39 > > I appreciate any assistance. > > -- View this message in context: http://www.nabble.com/Error-when-verifying-signature-tp18391044p18392879.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
