All the Digest authenticators for Squid needs to do is to return the
current HA1 Digest hash value for the user. This is the same has as
generated by the Apache htdigest command and documented in RFC2617, or in
use Digest::MD5 qw(md5_hex);
my $HA1 = md5_hex( join(":", $user, $realm, $password) );
The realm must match what you have set in squid.conf auth_param digest
The exact details on the Digest authenticator helper protocol syntax is
documented in squid.conf..
