Secure Back Door (SBD) is a tool that provides
ultra-secure and minimal access to a computer,
which allows you to run a single command based on
a one time key. It is good if you don't want to
have an SSH server running all the time, and only
want to start it when needed. Because it is
written in only a few lines of code, it is hoped
that it will be less susceptible to security
exploits than a program like SSH.
