Thanks Paulo!
I changed VERISIGN_SIGNED to WINCER_SIGNED. That removed the plug-in
message. Acrobat didn't recognize the Verisign root certificate until I
changed the security settings to use all Windows root certificates. Does
that jive with your experience?
I still can't get the signature graphic to display. Are there any rules
for the image format, size, or color depth? No matter what I try, I
don't see an image.
Thanks!

Subject: [iText-questions] problems signing PDFs using a
Verisign certificate
I'm having two problems signing PDFs using a Verisign
certificate with
iText 2.0.4.
1. I'm including an Image of the handwritten signature using
setSignatureGraphic. The signed PDF that iText produces does not show
the image, though.
Works for me using your code.
2. When I open the signed document in Acrobat Reader 8, it
tells me that
"The validity of the document is UNKNOWN. The plug-in required is not
available.". When I click on the signature field, it tells me
that the
Verisign.PPKVS plug-in cannot be found. I have searched on Verisign's
web site with no luck in finding such a plug-in.
Use PdfSignatureAppearance.WINCER_SIGNED. The verisign mode was for the
old Acrobat 5 plug-in and it's not needed anymore.
Paulo
Any help with these two issues would be very appreciated.
Carl
ps. In case it helps. here is my code:
KeyStore ks = KeyStore.getInstance("pkcs12");
ks.load(new
FileInputStream("C:/tt/csayres.pfx"),password.toCharArray());
String alias = (String)ks.aliases().nextElement();
PrivateKey key = (PrivateKey)ks.getKey(alias,password.toCharArray());
java.security.cert.Certificate[] chain =
ks.getCertificateChain(alias);
PdfReader pdfReader = new PdfReader(new
FileInputStream("C:/tt/in.pdf"));
FileOutputStream fos = new FileOutputStream("C:/tt/out.pdf");
PdfStamper stamper = PdfStamper.createSignature(pdfReader,fos,'\0');
PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
Image img = Image.getInstance("C:/tt/csayres.png");
appearance.setRender(PdfSignatureAppearance.SignatureRenderGra
phicAndDescription);
appearance.setSignatureGraphic(img);
appearance.setAcro6Layers(true);
appearance.setVisibleSignature(new
Rectangle(97.51f,234.24f,378.38f,253.41f),4,null);
appearance.setCertificationLevel(PdfSignatureAppearance.CERTIF
IED_NO_CHANGES_ALLOWED);
appearance.setCrypto(key,chain,null,PdfSignatureAppearance.VER
ISIGN_SIGNED);
stamper.close();
