Got a Secure Sockets Layer (SSL) certificate, acquired from 
Namecheap, issued by 
RapidSSL, installed on the 
Elastic Compute Cloud (EC2) web server instance hosting 
Devil Music.
Follow the tutorial How to Configure an SSL Certificate for Apache on Amazon EC2 on splittingelectrons. Also consult the relevant RapidSSL Technical Support articles RapidSSL – Generate Certificate Signing Request (CSR) and RapidSSL – Install SSL Certificate.
* Since the splittingelectrons blog has not been updated in 2 years, I’ve copied its contents into an HTML comment embedded in this post so it doesn’t get lost.
[UPDATE Monday, December 1, 2014]
Beginning next summer (2015), you should look into 
Let’s Encrypt as your *free* certificate authority!
