/*
 * This is the actual card emulator.
 *
 * These functions can be implemented in different ways on different platforms
 * using the underlying system primitives. For Linux it uses NSS, though direct
 * to PKCS #11, openssl+pkcs11, or even gnu crypto libraries+pkcs #11 could be
 * used. On Windows CAPI could be used.
 *
 * This work is licensed under the terms of the GNU LGPL, version 2.1 or later.
