Looking at the January 2002 mailing list archive, it becomes clear
that while the public key types defined in the transport draft have
this encoding:

     string   certificate or public key format identifier
     byte[n]  key/certificate data

there is no requirement that public key types defined elsewhere will
have that encoding.  Perhaps the gsskeyex draft should explicitly say
that SSH_MSG_KEXGSS_HOSTKEY only works with ssh-dss and ssh-rsa keys,
or that it only works with types that start out with the type
identifier as a string.
