Next week I'll have a new release that will support signatures with the modes self sign, verisign and the new Acrobat 6 Windows Certificate Security. You can see then how it's done. In any case the BC library is not magic and in my particular case I only use the classes for the DER encoding/decoding, not the cms classes. If you are new to signatures, pkcs#7 and so on you should first read a book on cryptography.
