Getting SSL up and running on OS X is not too difficult these days. First you need to tell it to read the SSL config file (removing red lines, adding green lines):
--- /etc/apache2/httpd.conf 2008-06-11 03:42:25.000000000 +0200
+++ /etc/apache2/httpd.conf.dist 2008-06-11 04:15:15.000000000 +0200

Notice that I'm using client certificates for authentication but you can comment out the
SSLCACertificateFile,
SSLVerifyClient and
SSLVerifyDepth options if you don't need this. If you do you'll want to grab the root from CAcert:
# curl -o server-ca.crt https://www.cacert.org/certs/root.crt
You'll want to generate random nubmers (key) and a certificate signing request (csr) in order to get a certificate (crt) file, and despite most information on the topic this can be done in one command:
# openssl req -newkey rsa:2048 -nodes -keyout server.key -out server.csrGenerating a 2048 bit RSA private key

writing new private key to 'server.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:New South Wales
Locality Name (eg, city) []:Sydney
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Australian Online Solutions Pty Ltd
Organizational Unit Name (eg, section) []:Security
Common Name (eg, YOUR name) []:secure.samj.net
Email Address []:xxxx@samj.net
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
Actually in the case of
CAcert.org everything except the common name is ignored so you can leave it as defaults.
For testing we'll use a script which prints all the environment variables (this is what I was after for my certificate authentication anyway):
# cat /Library/WebServer/CGI-Executables/printenv
#!/bin/bash
echo "Content-type: text/plain"
echo ""
printenv
And when you browse to your machine (eg
https://secure.samj.net/) you should see something like this:
