I didn't look at your code in detail, but at first glance I see that you're using an old version of iText. I also think you're using PKCS#1 which is allowed in ISO-32000-1, but forbidden in PAdES (but that doesn't explain your problem). In any case, the signing process in iText was completely refactored in iText 5.3.0; and the refactoring is almost completed. This week we'll release iText 5.3.2 with some extra changes to the API, and then the interface will be stable. After the release, we'll send the second draft of the white paper about digital signatures to all the subscribers of our newsletter: http://itextpdf.com/newsletter You can consult the table of contents of that white paper here: http://itextpdf.com/book/digitalsignaturesTOC.pdf The parts in gray haven't been written yet. As you can see, there are already two examples explaining how to sign with an USB token, one using MSCAPI, another using PKCS#11. You may want to wait a couple of days until the draft is released. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
