In my previous post I described how to securely acquire the Mozilla list of root certificates and convert them to a form usable by curl and various libraries which don't ship with them.

Next, I want to point Net:HTTP at this file library-wide, so that it is used by all invocations of methods accessing https resources (in particular, Kernel#open, which in ruby 1.8.7 does not have a ca_file option and is therefore unusable with https). I hunted around the ruby standard library for a couple hours and came up with this:

require 'open-uri'
require 'net/https'

module Net
 class HTTP
