CAcert.org is a community-driven Certificate Authority that issues certificates to the public at large for free.
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
Comments and Reviews
After CACert's breach, their CA public certs were removed from all the major browsers and operating systems. This means that any website using a certificate issued by them would now show as untrusted. CACert is to be avoided as there is no going back once you've opened the doors and allowed anyone to issue a certificate for any domain name they want, especially domain names they don't control such as gmail, yahoo, hotmail, etc... as was the case with CACert.
