Keyless SSL is only available to Enterprise customers that maintain their own SSL certificate purchased from a valid Certificate Authority. Cloudflare does not supply any certificates for use with Keyless SSL.
I’m not part of any Enterprise organization and I’m too poor to sign up for Enterprise level service, and so I am unable to use their Keyless SSL.
Just for example. Sometimes it’s not that we don’t want to but can’t afford to, especially if we’re just Joe Schmoe running a handful of services on a server box.
Once again, I have no issues with Cloudflare myself, and personally have a decent amount of respect for them.
I’m just saying getting access to the Keyless SSL is less easy than you made it sound.
