I think that this is the better approach.  The question I have is why 
the SSH logic should be dependent on the implementation details of ANY 
particular cryptographic library (be it openssl, libressl or whatever)? 
Proper software design would develop an abstraction layer with some 
measure of forward compatibility built in.
