GnuPG for Debian ================ A comprehensive manual (the GNU Privacy Handbook) is included in the gnupg-doc package. It can also be found online at . Smart card readers ------------------ If udev, consolekit, and gnupg are installed, then locally logged-in users will be automatically granted permission to access any detected USB SmartCard reader devices. /lib/udev/rules.d/60-gnupg.rules lists the supported devices. If yours is not listed there, you can try creating a copy of that file in /etc/udev/rules.d/ with your device’s information. Wishlist bugs against the gnupg package about unsupported devices would be welcome.
