ssh-keysign.8(8)

     NAME
          ssh-keysign - ssh helper program for hostbased
          authentication

     SYNOPSIS
          ssh-keysign

     DESCRIPTION
          ssh-keysign is used by ssh(1) to access the local host keys
          and generate the digital signature required during hostbased
          authentication with SSH protocol version 2.  ssh-keysign is
          not intended to be invoked by the user, but from ssh(1).
          See ssh(1) and sshd(8) for more information about hostbased
          authentication.

     FILES
          /etc/openssh/ssh_host_dsa_key, /etc/openssh/ssh_host_rsa_key
               These files contain the private parts of the host keys
               used to generate the digital signature.  They should be
               owned by root, readable only by root, and not
               accessible to others.  Since they are readable only by
               root, ssh-keysign must be set-uid root if hostbased
               authentication is used.
