NAME

RT::Extension::Captcha - solve a CAPTCHA before some actions in RT

DESCRIPTION

This extension is for RT 4.2 or newer. It requires solving captchas when a user creates a ticket (using either regular interface or quick create) and on replies/comments (updates).

INSTALLATION

perl Makefile.PL

make

make install

May need root permissions

Edit your /opt/rt5/etc/RT_SiteConfig.pm

Add this line:

    Plugin('RT::Extension::Captcha');

Clear your mason cache

    rm -rf /opt/rt5/var/mason_data/obj

Restart your webserver

CONFIGURATION

No CAPTCHA rights

Users who have right 'NoCaptchaOnCreate' or 'NoCaptchaOnUpdate' will see no captchas on corresponding actions.

Font

As GD's builtin font is kinda small. A ttf font is used instead. By default font defined by ChartFont option (RT's option to set fonts for charts) is used for CAPTCHA images.

As well, you can set font for cpatchas only using "%Captcha option" described below.

%Captcha option

See etc/Captcha_Config.pm for defaults and example. %Captcha option is a hash. Now, only ImageProperties key has meaning:

    Set(%Captcha,
        ImageProperties => {
            option => value,
            option => value,
            ...
        },
    );

ImageProperties are passed into "new" in GD::SecurityImage. Read documentation for the module for full list of options.
