I hope this article has helped you to understand the issues with blindly
accepting SSL certificates or at least to understand that *if you don't
want to verify SSL certificates, don't use SSL.*
*Updated on 2015-02-26 10:43Z: just use environment variables in the
function like suggested by @DarthGandalf on \#znc.*
