			This uses the bash here string <code><<<</code> in order to have <code>stdin</code> available as a regular file <code>/dev/stdin</code> rather than a pipe as ssh-keygen will only operate on a file. As of Release 7.2 of openssh ssh-keygen supports fingerprinting from standard input: <tt>ssh-keygen(1): allow fingerprinting from standard input, e.g. "ssh-keygen -lf -"</tt>.
