Concerning OCF in general, you have to use a CardService that
implements the "opencard.opt.signature.SignatureCardService" interface.
More details can be found in the "OpenCard Framework 1.2 Programmer's
Guide" (see
http://www.opencard.org/docs/pguide/PGuide.html#HDRSIGNATUREGENERATIONANDVER
)
or in this book: http://www.opencard.org/SCJavaBook/ .
Concerning the GPK8000, the "GPKSignatureService" implements this
interface. From the GPK and Generic CardServices that can be downloaded
at:
http://www.gemplus.fr/developers/technologies/opencard/cardservices/download.html
There is not a lot of docs on how to use them I'm afraid, but they
should
behave as in the OCF guides. Also you can check the source of the tests
(gemplus-gpk-0.2/src/test/GPKTest.java), see the "testPK()" methods that
involves key generation, data signing and verifying).
Hope it'll help.
Cheers,
Christophe.
