CGI::Application::Plugin::Authentication::Store::Cookie - Cookie based Store
This document describes CGI::Application::Plugin::Authentication version 0.20
use base qw(CGI::Application);
STORE => [Cookie, SECRET => "Shhh, dont tell anyone", NAME => CAPAUTH_DATA, EXPIRY => +1y],
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.
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 dont 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
STORE => [Cookie, SECRET => "Shhh, dont 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.
This module requires the following modules to be available.
This method accepts a list of parameters and fetches them from the cookie data.
This method accepts a hash of parameters and values and stores them in the cookie data.
This method accepts a list of parameters and deletes them from the cookie data.
This method will check for an existing cookie, and decode the contents for later retrieval.
This method will return the name of the cookie
