Example

narbeh@narbeh-xps:~/ssl-checker$ ./ssl_checker.py -H test.com narbeh.org:443 archive.org facebook.com:443 twitter.com github.com google.com
Analyzing 7 hosts:

	[+] test.com             Expired: False
	[+] narbeh.org           Expired: False
	[+] archive.org          Expired: False
	[-] facebook.com         Failed: [Errno 111] Connection refused
	[-] twitter.com          Failed: [Errno 111] Connection refused
	[+] github.com           Expired: False
