description="
The OpenSSH suite.

OpenSSH is the premier connectivity tool for remote login with the SSH
protocol.  It encrypts all traffic to eliminate eavesdropping,
connection hijacking, and other attacks.  In addition, OpenSSH provides
a large suite of secure tunneling capabilities, several authentication
methods, and sophisticated configuration options.
