SYNOPSIS
htdigest [ -c ] passwdfile realm username
SUMMARY
htdigest is used to create and update the flat-files used to store user-
names, realm and password for digest authentication of HTTP users. Re-
sources 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/.
OPTIONS
-c Create the passwdfile. If passwdfile already exists, it is
deleted first.

details.
