I have sign an pdf using acrobat7. But when I useing iText to verify it by the sample
PdfPKCS7 p7 = acroFields.verifySignature(name);
I got an exception¡Gsun.security.pkcs.ParsingException: toDerInputStream rejects tag type -96
Can any one know why this happen or how to solve?
I think this should be a simplest situation, but I can't find what's wrong.
