Yes, this is certainly possible. I think some of the yuibkey devices [0] may support this feature, and it should also be possible (with a bit of hardware hacking) to do it with the FST-01, which is the platform for the gnuk [1].

[1] http://www.fsij.org/category/gnuk.html If anyone is considering adding this kind of feature to the FST-01, i'd be happy to test and debug it with them. --dkg _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
