Hey,
I've been programmatically signing PDF documents, which is working ok as of
today. So I attempted to get the signing info from a document and verifying
it following Chapter 16 page 530 in the iText book.
I used a .be eID sample card from Certipost. The signing example in the
book works well btw.
At first I got a NoClassDefException on
org.bouncycastle.jce.provider.X509CertParser. So I added the library:
"bcprov-jdk1X.jar" library. But now it's even worse. I get the following
exception, without stacktrace. After debugging I pinned it down to the line
AcrofieldsInstance.verifySignature(name);
com.lowagie.text.ExceptionConverter
: class "org.bouncycastle.jce.provider.X509CertificateObject"'s signer
information does not match signer information of other classes in the same
package
The exception gets thrown here:
KeyStore ks = PdfPKCS7.loadCacertsKeyStore();
this.naam=name;
this.signatureCoversWholeDocument=fields.signatureCoversWholeDocument(naam);
this.verifiedSig=fields.verifySignature(name);
--------> signDatum = verifiedSig.getSignDate(); <----------------
certificaten = verifiedSig.getCertificates();
Also.. :)
In line 1 of this code snippet, am I supposed to load the .be
rootcertificate? Not that I've used it as of yet but I probably will when I
get this first problem sorted out.
Thanks in advance :)
Cheers,
Thomas
