description: "A short note separating two questions about certificate authorities: anyone can create a CA, and OpenSSL walkthroughs show how. Becoming a trusted CA is a policy matter instead, so the post assembles the root-programme policies of Microsoft, Apple, Mozilla and Opera as the reference set."

Anyone can create a Certificate Authority. Check out this blog describing how to do it with [OpenSSL](http://www.freebsdmadeeasy.com/tutorials/freebsd/create-a-ca-with-openssl.php).

Becoming a trusted CA is a different story. Microsoft, Mozilla, Apple, and other browser companies and OS vendors have a policy stating what it takes to participate in their root CA programs.
