mod_http_oauth2: Use more compact IDs
UUIDs are nice but so verbose!
The reduction in entropy for the nonce should be fine since the
timestamp is also counts towards this, and it changes every second
(modulo clock shenanigans), so the chances of someone managing to get
the same client_secret by registering with the same information at the
same time as another entity should be negligible.

--- labels: - 'Stage-Beta' 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.
