NAME Plack::Middleware::Auth::Digest - Digest authentication SYNOPSIS enable "Auth::Digest", realm => "Secured", secret => "blahblahblah", authenticator => sub { my ($username, $env) = @_; return $password; # for $username }; # Or return MD5 hash of "$username:$realm:$password" enable "Auth::Digest", realm => "Secured", secret => "blahblahblah", password_hashed => 1, authenticator => sub { return $password_hashed }; DESCRIPTION Plack::Middleware::Auth::Digest is a Plack middleware component that enables Digest authentication. Your "authenticator" callback is called using two parameters: a username as a string and the PSGI $env hash. Your callback should return a password, either as a raw password or a hashed password. CONFIGURATIONS authenticator A callback that takes a username and PSGI $env hash and returns a password for the user, either in a plaintext password or a MD5 hash of "username:realm:password" (quotes not included) when "password_hashed" option is enabled. password_hashed A boolean (0 or 1) to indicate whether "authenticator" callback returns passwords in a plaintext or hashed. Defaults to 0 (plaintext). realm A string to represent the realm. Defaults to *restricted area*. secret Server secret text string that is used to sign nonce. Required. nonce_ttl Time-to-live seconds to prevent replay attacks. Defaults to 60. LIMITATIONS This middleware expects that the application has a full access to the headers sent by clients in PSGI environment. That is normally the case with standalone Perl PSGI web servers such as Starman or HTTP::Server::Simple::PSGI. However, in a web server configuration where you can't achieve this (i.e. using your application via mod_perl, CGI or FastCGI), this middleware does not work since your application can't know the value of "Authorization:" header. If you use Apache as a web server and CGI or mod_perl to run your PSGI application, you can use mod_rewrite to pass the Authorization header to the application with the rewrite rule like following.
