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.

Paulo Soares
