# Workaround for Python's order-indifference in dicts. We might get a random RSA type (ssh-rsa, rsa-sha2-256, or rsa-sha2-512), so running the tool against the same server three times may give three different host key types here. So if we have any RSA type, we will simply hard-code it to 'ssh-rsa'.
