NAME

       digest_file_auth - File based digest authentication helper for Squid.

       Version 1.1


SYNOPSIS

       digest_file_auth [-c] file


DESCRIPTION

       digest_file_auth is an installed binary authentication program for
       Squid. It handles digest authentication protocol and authenticates
       against a text file backend.  This program will automatically detect
       the existence of a concurrecy channel-ID and adjust appropriately.  It
       may be used with any value 0 or above for the auth_param children
       concurrency= parameter.


OPTIONS

       -c          Accept digest hashed passwords rather than plaintext in the
                   password file


CONFIGURATION

       Username database file format:

       - comment lines are possible and should start with a '#';

       - empty or blank lines are possible;

       - plaintext entry format is username:password

       - HA1 entry format is username:realm:HA1

       To build a directory integrated backend, you need to be able to
       calculate the HA1 returned to squid. To avoid storing a plaintext
       password you can calculate MD5(username:realm:password) when the user
       changes their password, and store the tuple username:realm:HA1.  then
       find the matching username:realm when squid asks for the HA1.

       This implementation could be improved by using such a triple for the
       file format.  However storing such a triple does little to improve
       security: If compromised the username:realm:HA1 combination is
       "plaintext equivalent" - for the purposes of digest authentication they
       allow the user access. Password syncronisation is not tackled by digest
       - just preventing on the wire compromise.
