Your SSH client will display the host key fingerprint the first time you try to connect to a server, or if it has no record of the server using that host key. When this happens you should always compare it to the published host key fingerprints for that server.
Below are the host key fingerprints for Compute Canada servers, as of July 12, 2019.

We currently offer a test node that you can use to test your client of choice before the [[SSH changes|change happens]]. You can connect to it using the hostname <code>ssh-test.computecanada.ca</code> using your regular Compute Canada credentials.  Its host key fingerprints are:

If you can connect successfully to <code>ssh-test.computecanada.ca</code> now, then you will continue to be able to connect to our clusters when the SSH changes are made in the summer of 2019.
== Another way to find host key fingerprints ==
You can also determine the host key fingerprints for a server with the following commands:
* for an MD5 fingerprint hash:
ssh-keyscan beluga.computecanada.ca | ssh-keygen -E md5 -l -f -
* for an SHA256 fingerprint hash:
ssh-keyscan beluga.computecanada.ca | ssh-keygen -E sha256 -l -f -
