Yes -- the public keys generated by OpenSSH and SSH Corp versions of
ssh(1) are in different formats.  You can use ssh-keygen(1) to convert
a public key produced by the SSH Corp product into a format the
OpenSSH can cope with:

    % ssh-keygen -i -f ssh-corp-key.pub > openssh-key.pub

Or you can got the other way round:

    % ssh-keygen -e -f openssh-key.pub > ssh-corp-key.pub

('i' is for import, 'e' is for export).  You want to do the second,
and then copy the transformed public key into the authorized_keys file
on the target host.

	Cheers,
