This tool displays SSH host key fingerprint - through HTTPS. SSH is about security; host key matters a lot here; and you can know for sure by using this tool. It means you know precisely how to answer this question: The authenticity of host 'blah.blah.blah (10.10.10.10)' can't be established. RSA key fingerprint is a4:d9:a4:d9:a4:d9a4:d9:a4:d9a4:d9a4:d9a4:d9a4:d9a4:d9. Are you sure you want to continue connecting (yes/no)? https://checkssh.com/ We hackers don't want to get hacked. :-) SSH rocks - when host key is right. Enjoy! Best Wishes,
