Some change in the protocol is required to implement this feature. >From here, it's development thing. Please skip reading, if you don't need. Most easy change would be adding a new flag into Slot Status register in the CCID specification 1.1. See page 55 of the specification for the Table 6.2-3 Slot Status register. Say, using bit-2 as: waiting user interaction flag, when Time extension is required. With that flag, the device will be possible to notify scdaemon (then, gpg-agent) to pop up dialog. Since we already have a flag in the card feature (in OpenPGPcard specification v3), we can distinguish if a card supports this feature or not. That is just a idea. I'll try with Gnuk Token, perhaps. -- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
