ssl - How to add HTTPS to Elastic Load Balancer?

I'm using boto to create an Apache http server that "hides" behind an AWS Elastic Load Balancer (ELB).
However, the ELB DNS address is functional only when I specify port 80 (http) in its security group. As soon as I add port 443 (https), I cannot get to content served by the Apache server.

Can anyone point to documentation/examples on how to add support for HTTPS to ELB?
(bonus points for information on how to use self signed SSL certificates).

Answer

Here is the AWS documentaion for setting up HTTPS/SSL Load Balancer:
