SSH host keys


Summary

SSH host keys securely identify SSH servers. When an SSH client connects to a server, the server presents a host key to the client. The client confirms the key has not changed from previous connections.

HCC tries to keep the SSH keys unchanged throughout the lifetime of a service, but security requirements evolve, and key changes may be necessary. If you get a key change warning, please confirm the fingerprint against the list below before updating your SSH client known hosts list. If the key fingerprint does not match, do not accept the new key and do not enter your credentials, and please contact HCC.

Example warning message

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
