Host Key Files
Host key files are read at startup from a standard location, by default
/etc/dropbear/dropbear_dss_host_key and /etc/dropbear/dropbear_rsa_host_key
or specified on the commandline with -d or -r. These are of the form generated

or specified on the commandline with -r. These are of the form generated
by dropbearkey. The -R option can be used to automatically generate keys
in the default location - keys will be generated after startup when the first
connection is established. This had the benefit that the system /dev/urandom
random number source has a better chance of being securely seeded.
