Warning CAcert cannot be trusted: they have serious code vulnerabilities, the coding style is very bad, and they failed an organizational practices audit that all other major certificate authorities have passed. Almost no browser or operating system supports CAcert, so any website using the certificate will trigger a big connection / untrusted certificate warning that will drive most visitors away. https://tinyurl.com/cacert-got-what-you-paid-for | https://www.reddit.com/r/technology/comments/1qj1tz/http_20_to_be_https_only/cddfmz0
