description         OpenSSH secure login server

long_description    OpenSSH is a FREE version of the SSH protocol suite of \
                    network connectivity tools that increasing numbers of people on the \
                    Internet are coming to rely on. Many users of telnet, rlogin, ftp, \
                    and other such programs might not realize that their password is \
                    transmitted across the Internet unencrypted, but it is. OpenSSH \
                    encrypts all traffic (including passwords) to effectively eliminate \
                    eavesdropping, connection hijacking, and other network-level \
                    attacks. Additionally, OpenSSH provides a myriad of secure \
                    tunneling capabilities, as well as a variety of authentication \
                    methods.
