  if the user runs the same process with the same keys, wouldn't the
user get the same response, which isn't working.

If the issue is the older ssh-rsa key, are you implying that that key
would be useful/err free if the client/server handles the rsa-sha2?
(even with old key) Or does the user have to regen, using the rsa-sha2
implementation?

thanks
