Plack::Middleware::Auth::Digest - Digest authentication
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 };
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.
authenticator
$env
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).
A string to represent the realm. Defaults to restricted area.
Server secret text string that is used to sign nonce. Required.
Time-to-live seconds to prevent replay attacks. Defaults to 60.
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 Apache's mod_cgi), this middleware does not work since your application can't know the value of Authorization: header.
Authorization:
If you use Apache as a web server and CGI to run your PSGI application, you can either a) compile Apache with -DSECURITY_HOLE_PASS_AUTHORIZATION option, or b) use mod_rewrite to pass the Authorization header to the application with the rewrite rule like following.
-DSECURITY_HOLE_PASS_AUTHORIZATION
RewriteEngine on RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
