SSH Fingerprints Website

If you're connecting the first time to a SSH Server you will perhaps get an alert message. The fingerprint should also be shown right below the message.

Linux

You can check if the fingerprint is correct with this website (https://ssh-fingerprints.ee.ethz.ch/).

The website contains the SSH fingerprints of every SSH server we manage.

Type in the hostname you want to connect to into the search bar on the top right corner of the website. The host with its fingerprint should now be shown in the table. Compare the fingerprint with the alert message. If it's the same fingerprint as shown then you can safely trust the connection.

Example for bad connection
