Perfect, thanks for the details.

I suspect RSA is the "best" WolfSSL 4.6.0 supports. And I'm ok with 
NO_DSA staying in effect:

     http://www.openssh.com/legacy.html

     OpenSSH 7.0 and greater similarly disable the ssh-dss (DSA)
     public key algorithm. It too is weak and we recommend against
     its use.

PR #700 created.
