NAME ^

Template::Plugin::GantryAuthCookie - decrypter for AuthCookie plugin

SYNOPSIS ^

In a Template Toolkit:

    [% USE decrypter = GantryAuthCookie( {
            cookie        = cookies.cookie_name,
            conf_instance = 'gantry_conf_instance',
            conf_file     = '/etc/strange.gantry.conf',
       } ) %]

    [% user_name = decrypter.user_name %]

conf_file is optional and defaults to /etc/gantry.conf

Alternatively, you could omit conf_instance and conf and directly supply the auth_secret key:

    [% USE decrypter = GantryAuthCookie( {
            cookie        = cookies.cookie_name,
            auth_secret   = env.auth_secret
       } ) %]

In httpd.conf (or something it includes):

    PerlModule Apache::Template
    PerlSetEnv auth_secret '$ecr3t'
    TT2Params  cookies env

    <Files *.something>
        SetHandler  perl-script
        PerlHandler Apache::Template
    </Files>

DESCRIPTION ^

You don't need this module if your page is generated by a Gantry controller. In that case, you can use Gantry::Plugins::AuthCookie and call its validate_user function directly. Use this when you need to display user information on a page which is generated by Apache::Template.

This module is a Template Toolkit plugin for decrypting Gantry::Plugins::AuthCookie cookies. In the USE statement in your template, pass at least the contents of the cookie and either the name of your Gantry::Conf instance or your auth_secret. If your master Gantry::Conf file is not /etc/gantry.conf, it as well.

You must define auth_secret in Gantry::Conf, or pass it directly. If you pass it directly, you probably want to use PerlSetEnv to keep it out of the template. That's what I did in the SYNOPSIS above.

METHODS ^

new

Called for you by TT when you USE the plugin. There are four parameters:

    cookie        - the auth cookie content
    conf_instance - your Gantry::Conf instance
    conf_file     - your master Gantry::Conf file (optional)
    auth_secret   - the compression secret key

Usually you get the cookie contents from the Apache::Template module's TT2Params cookies parameter. If you pass the secret directly, you should get it by these commands in httpd.conf:

    PerlSetEnv  auth_secret '4our$ecr3t1ssaf3'
    TT2Params   cookie env

Then fish it out of the env hash in your template. See the SYNOPSIS above.

user_name

Returns the name of the user from the cookie, if there is one.

auth_secret

Used by Gantry::Plugins::CRUD to retrieve the decryption key. This is taken from the Gantry::Conf variable or constructor argument of the same name. Precendence is given to the constructor argument if both are suppied.
