Checks whether the SSL certificate used by a host has a fingerprint that matches an included database of problematic keys.
The only databases currently checked are the LittleBlackBox 0.1 database of compromised keys from various devices and some keys reportedly used by the Chinese state-sponsored hacking division APT1 (https://www.mandiant.com/blog/md5-sha1/). However, any file of fingerprints will serve just as well. For example, this could be used to find weak Debian OpenSSL keys using the widely available (but too large to include with Nmap) list.
Specify a different file to read fingerprints from.
