NAME

       CGI::Application::Plugin::Authentication::Store::Cookie - Cookie based Store

VERSION

       This document describes CGI::Application::Plugin::Authentication version 0.20

SYNOPSIS

        use base qw(CGI::Application);
        use CGI::Application::Plugin::Session;
        use CGI::Application::Plugin::Authentication;

         __PACKAGE__->authen->config(
               STORE => ['Cookie', SECRET => "Shhh, don't tell anyone", NAME => 'CAPAUTH_DATA', EXPIRY => '+1y'],
         );

DESCRIPTION

       This module uses a cookie to store authentication information across multiple requests.
       It works by creating a cookie that contains the information we would like to store (like
       the name of the user that is currently authenticated), and then base64 encoding the data.
       In order to ensure that the information is not manipulated by the end-user, we include a
       CRC checksum that is generated along with our secret.  Since the user does not know the
       value of the secret, they will not be able to recreate the checksum if they change some of
       the values, so we will be able to tell if the information in the cookie has been
       manipulated.

THE SECRET

   Choosing a good secret
       An easy way to generate a relatively good secret is to run the following perl snippet:

         perl -MDigest::MD5=md5_base64 -l -e 'print md5_base64($$,time(),rand(9999))'

       Just use the resulting string as your secret.

   Configuring the secret
       There are three ways that you can provide a secret to the module:

       Hardcode the secret
           You can hardcode a secret right in the
           CGI::Application::Plugin::Authentication::Store::Cookie module, so that you don't have
           to remember to provide one every time you use the module.  Just open the source in a
           text editor and look at the top of the file where it defines 'our $SECRET' and follow
           the instruction listed there.

       Provide the SECRET option when using the module
           You can also just provide the secret as an option when using the module using the
           SECRET parameter.

             __PACKAGE__->authen->config(
                   STORE => ['Cookie', SECRET => "Shhh, don't tell anyone"],
             );

       Let the module choose a secret for you
           And lastly, if you forget to do either of these, the module will use the name of your
           application as the secret, but that is not a very good value to use, so a warning will
           be spit out everytime it uses this.  This is the least desirable choice, and is only
           included as a last resort.
