mod_http_oauth2: Add support for the "openid" scope This "openid" scope is there to signal access to the userinfo endpoint, which is needed for OIDC support. We don't actually check this later because the userinfo endpoint only returns info embedded in the token itself, but in the future we may want to check this more carefully.

summary: provides captcha protection for registration form
...

Introduction
============

Prosody-captcha is a little modification of prosody's
"mod\_register.lua" module that provides captcha protection for
registration form.

Installation
============

First of all you should build and install lua bindings for libgd —
[lua-gd](https://github.com/ittner/lua-gd/).

Then clone repsository lua-captcha:

    $ git clone https://github.com/mrDoctorWho/lua-captcha

install it:

    $ make install

Configuration
=============

After that you would configure prosody. This module requires from you 4
fields, you should add this into your VirtualHost entry.

    captcha_config = {
            dir = "/tmp"; -- Directory used to storage captcha images. Please make sure prosody user allowed to write there.
            timeout = 60; -- Timeout when captcha will expire
            web_path = "challenge"; -- Web path used to separate main prosody site from itself modules.
            font = "/usr/lib/prosody/FiraSans-Regular.ttf" -- Font used for captcha text
    }

You can run script "install.lua" to install this or instead of that
while prosody developers didn't accepted "dataforms" changes you should
replace standard prosody "dataforms.lua" located in ubuntu in
/usr/lib/prosody/util by another one from this repository. You should do
the same thing with "mod\_register.lua" located in ubuntu in
/usr/lib/prosody/modules.

After this all you can try to register on your server and see the
captcha.

TODO
====

-   Maybe use recaptcha instead of libgd.
