Don't think so. The remote server will send either ssh-rsa, ssh-rsa2
or ssh-dss. The client only needs the contents of whichever key was
sent and some way to work out which format it is? (this might be
embedded in the key. I can't remember).

The sha-1 key is just another type of hashed key and libssh2 allows
you to fetch MD5 or SHA1. I'm not sure I see the point of having two
hash formats.
