# htdigest - manage user files for digest authentication

Available Languages: en | ko | tr

`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/.

`htdigest [ -c ] passwdfile realm username`

## Options

`-c`
  Create the passwdfile. If passwdfile already exists, it is deleted first.
`passwdfile`
  Name of the file to contain the username, realm and password. If `-c` is given, this file is created if it does not already exist, or deleted and recreated if it does exist.
`realm`
  The realm name to which the user name belongs. See http://tools.ietf.org/html/rfc2617#section-3.2.1 for more details.

## Security Considerations

This program is not safe as a setuid executable. Do not make it setuid.
