Universal SSL: Encryption all the way to the origin, for free

CloudFlare has introduced a new Origin CA service, providing free limited-function certificates for customer origin servers. This public beta aims to provide full encryption of all data from the browser to the origin server at no cost. The service offers three modes for HTTPS: Flexible, Full and Strict. Sites on CloudFlare's Free plan default to Flexible SSL mode, but customers can now get a free certificate directly from CloudFlare for their Strict SSL mode. To sign up for the beta, send an email with a Certificate Signing Request (CSR), domain name and zone information. The Origin CA is not currently trusted by browsers, so these certificates should only be used on sites that are behind CloudFlare.
