On another Debian machihe, I can see that ssh-vulnkey outputs
"Unknown (no blacklist information)" for the RSA key, probably
because openssh-blacklist-extra isn't installed on this machine.
The description field of openssh-blacklist-extra says:
"list of non-default blacklisted OpenSSH RSA and DSA keys"
I wonder why "non-default", because all these keys were generated
automatically when Debian was installed.
