    Warning

    CAcert can't be trusted: It has serious code vulnerabilities, the coding style is very bad & they failed an organizational-practices audit which all other major certificate authorities have passed. Almost no browsers or operating systems support CAcert, so any website using the certificate will trigger a big untrusted connection/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
