1.1       markus     33: .Sh DESCRIPTION
                     34: .Nm
                     35: is used by
                     36: .Xr ssh 1
1.2       stevesk    37: to access the local host keys and generate the digital signature
                     38: required during hostbased authentication with SSH protocol version 2.
1.1       markus     39: .Nm
                     40: is not intended to be invoked by the user, but from
                     41: .Xr ssh 1 .
                     42: See
                     43: .Xr ssh 1
                     44: and
                     45: .Xr sshd 8
                     46: for more information about hostbased authentication.

                     49: .It Pa /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
                     50: These files contain the private parts of the host keys used to
                     51: generate the digital signature.  They
                     52: should be owned by root, readable only by root, and not
                     53: accessible to others.
                     54: Since they are readable only by root,
                     55: .Nm
                     56: must be set-uid root if hostbased authentication is used.
