I am attempting to enable https://mysite.com on my small Ubuntu 11.04/Apache 2 I adopted several guides online, however i still cannot access https://mysite.com

The guides pointed out getting certificates from CA, does which means that I must register somewhere?

Or, can one simply redirect all https visitors to http?

Yes. You need and install an SSL certificate.

The entire reason for SSL is the fact that a reliable 3rd party certifies your identity.

You will have to educate yourself on SSL or bring in help.

Best of luck
