While it’s possible to add/delete hosts, key, certificates, there’s no reasonable way to manage known_hosts

[rcfa]

There’s no usable editor (ed doesn’t count) to manage the .ssh/known_hosts either by UI or via an usable built-in editor host fingerprints change, particularly in a test environment where “the same” machine is set up repeatedly and end up with different ssh fingerprints. Managing this, currently means simply deleting the known_hosts file (because well, ed is hell), which carries risks, as one has to re-add all previously known hosts, and eventually one just says yes, without actually checking finger prints.

Adding to backlog as we are focusing on improving these flows.

There is ssh-keygen -r, but poorly discoverable.
