NAME

       CurveCP -- Message-handling programs

SYNOPSIS

       curvecpmessage [-q (optional)]  [-Q (optional)]	[-v (optional)]  [-c (optional)]  [-C (optional)]  [-s (optional)]  [prog]

DESCRIPTION

       This manual page documents briefly the CurveCP commands.

       A  traditional UNIX-style server such as ftpd handles just one network connection, reading input from stdin and writing output to stdout. A
       "superserver" such as inetd or tcpserver listens for network connections and starts a separate server process for each connection.

       The CurveCP command-line tools have an extra level of modularity. The curvecpserver  superserver listens for network connections. For  each
       connection,  curvecpserver  starts the curvecpmessage message handler; curvecpmessage then starts a server such as ftpd.  Then ftpd sends a
       stream of data to curvecpmessage, which in turn sends messages to curvecpserver, which encrypts and authenticates the  messages	and  sends
       them  inside  network  packets. At the same time curvecpclient receives network packets, verifies and decrypts messages inside the packets,
       and passes the messages to curvecpmessage; curvecpmessage sends a stream of data to ftpd.  The same curvecpmessage tool	is  also  used	by
       curvecpclient.

       curvecpserver  and  curvecpclient  can use programs other than curvecpmessage. Those programs can directly generate messages in the CurveCP
       message format without talking to separate tools such as ftpd; or they can support a completely different protocol  that  reuses  CurveCP's
       cryptographic layer but transmits different kinds of messages.
