The SSHFP format is gibberish to me (it looks rather short, BTW), so I can't just copy it to known_hosts. And as long as we don't have DNSSEC working (including matching software on my side), I can't just tell SSH to trust DNS.

Thanks for benders key! I suppose none of the others has changed recently?

I would have to look it up (there's been a recent thread about it on
cryptography at metzdowd.com), but TBH I never noticed any difference in
connect latency between 2kb and 4kb RSA so I wouldn't even think about
choosing 2kb myself on most hosts. I usually keep whatever the system
has generated for me, though - yes, I'm lazy. :-P
