These are the fingerprints of the SSH public keys. If you connect to the server via SSH, your client will ask you if it's the correct server you want to connect to and shows the fingerprint of the offered public key. It should be one of these. If the shown fingerprint is not in the list of fingerprints below, you are being tampered!
