       htdigest - manage user files for digest authentication

       htdigest [ -c ] passwdfile realm username

       htdigest  is  used  to  create  and update the flat-files used to store
       usernames, realm and password for digest authentication of HTTP  users.
       Resources  available  from  the Apache HTTP server can be restricted to
       just the users listed in the files created by htdigest.

       This manual page only lists the command line arguments. For details  of
       the  directives  necessary  to configure digest authentication in httpd
       see the Apache manual, which is part of the Apache distribution or  can
       be found at http://httpd.apache.org/.
