gnupg: Scdaemon Protocol

 
 6.6 Scdaemon's Assuan Protocol
 ==============================
 
 The SC-Daemon should be started by the system to provide access to
 external tokens.  Using Smartcards on a multi-user system does not make
 much sense except for system services, but in this case no regular user
 accounts are hosted on the machine.
 
    A client connects to the SC-Daemon by connecting to the socket named
 '/var/run/gnupg/scdaemon/socket', configuration information is read from
 /ETC/GNUPG/SCDAEMON.CONF
 
    Each connection acts as one session, SC-Daemon takes care of
 synchronizing access to a token between sessions.
