%description
    Secure Shell (SSH) is a facility for logging into a remote machine
    and for remotely executing commands on a remote machine. It is
    intended to replace rlogin(1) and rsh(1), and provide secure
    encrypted communications between two untrusted hosts over an
    insecure network. X11 connections and arbitrary TCP/IP ports can
    also be forwarded over the secure channel. OpenSSH is OpenBSD's
    rework of the last free version of SSH, bringing it up to date in
    terms of security and features, as well as removing all patented
    algorithms to separate libraries (OpenSSL).
