Yes, but the *server* advertised its RSA key (only, which also seems weird, as
it should have been also advertising DSA if not disabled and - if DSA were
disabled, most likely also ECDSA and ED keys), while the client/libssh only
advertised supporting ED-type keys. That's what makes this so wicked.
