This post assumes that:

1. You are hosting with TurnkeyWebHosting.com
2. You have access to your Siteworx control panel

Tip: If you want the cheapest price from GoDaddy on an SSL, Google "SSL cert". GoDaddy's sponsored link will be right at the top. Click on it and make your purchase. Their Standard SSL will be $12.99 instead of $49.99.

My thanks to Jon from Interworx, and Dirk from GoDaddy, for all their help with my SSL install.

Here we go:

1. Launch your web browser
2. Type in your Siteworx web address in the address bar (e.g. http://www.mydomain.com/siteworx/)
Tip: You may receive a certificate warning. This is due to the security certificate using the web host's domain name instead of yours; just carry on citizen

3. Login with the username and password TurnkeyWebHosting.com emailed you when you signed up
4. On the left hand side of the screen, click "Hosting Features"
5. The menu will expand; click on "SSL Certificates"
6. Click [ Setup Private Key ]
Tip: Most, if not all, new SSLs are issued using 2048-bit RSA keys.

7. Select 2048-bit from the dropdown box
8. Click the Generate button
9. The top of your screen will say: Private key created
10. Click on "SSL Certificates"
11. Click [ Setup CSR ]
12. If your country has not already been chosen for you, type your two letter country code (e.g. US)
13. Type the two letter State or Providence code (e.g. NY for New York)
14. Type your City
15. Type your company's name
16. Type the Company division (e.g. Online Retail)
17. Choose the Common Name from the select box (e.g. mydomain.com)
18. Type your E-mail address (e.g. hi@mydomain.com)
19. Click the Generate button
20. The top of your screen will say: CSR created
21. Open a new tab in your web browser
22. Log into your GoDaddy account and follow these instructions: http://help.godaddy.com/article/562
23. Log in to your GoDaddy Account Manager
24. In the My Products section, select SSL Certificates

27. Click Download
28. Download your certificate for the Apache webserver
Tip: Keep these files in a safe place!

29. Click Download Certificate and specify a location to save the file
30. Click Close
31. Log out of your GoDaddy account
32. Close the GoDaddy tab
33. Minimize your web browser
34. Unzip the file you downloaded from GoDaddy
Tip: There should be two files: gd_bundle.crt and mydomain.com.crt. Make sure you have both!

35. Open mydomain.com.crt with a text editor (Windows users can use Notepad for this, Mac users can use TextMate, BBEdit, or something along those lines)
36. You'll see a lot of gobbledygook, don't worry, it's supposed to look that way
37. Highlight everything, from start to finish
38. Copy it (CTRL + C for Windows users, Command + C for Mac users)
39. Minimize your text editor
40. Maximize your web browser
41. Click on "SSL Certificates"
42. Click [ Setup SSL Certificate ]

You're almost done! Hang in there with me; you're doing great!

46. Click on "SSL Certificates"
47. Click [ Setup SSL Chain Certificate ]
48. Minimize your web browser
49. Maximize your text editor
50. Close mydomain.com.crt and open gd_bundle.crt
51. Highlight everything, from start to finish
