An extension of the basic
mod_auth module, instead of sending the user information in plain text,
mod_auth_digest is sent via the message digest 5 (MD5) authentication process. This authentication scheme is defined in RFC 2617, “HTTP Authentication: Basic and Digest Access Authentication.” Compared to using Basic Authentication, this is a much more secure way of sending user data over the Internet. Unfortunately, not all web browsers support this authentication scheme.
To create password files for use with
mod_auth_dbm, you must use the
htdigest utility. It has more or less the same functionality as the
htpasswd utility. See the man page of
htdigest for further information.
