How to setup Heroku Hostname SSL with GoDaddy SSL Certificate and Zerigo DNS
Heroku recently added an exciting new 'Hostname SSL' option.  This option offers the broad compatibility of IP-based SSL, but at 1/5 the price ($20 / month at the time of this writing).  
 
The following tutorial explains how to use Heroku's new 'Hostname SSL' option on your Heroku project.  Before we begin, let's list what we're using here:

    * Heroku Hostname SSL
    * GoDaddy Standard SSL Certificate
    * Zerigo DNS

/*
 To use: 
 1) Get path to file/folder using file selection dialog.
 2) Pass path to secscopGetBookmarkFromURL in order to get bookmark data for it.
 3) Store this bookmark data somehow.
 4) Tell the OS you want access to the file using secscopInitializeURLFromBookmarkData(). Store security-scoped url returned for later.
 5) When you are done using the file call secscopStopUsingURL.

 You will need to do steps 4 and 5 every time you want to open a file across sessions. For example, if you have a recent files menu or a folder that a user selects once and you write data to across sessions.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

The process starts by creating the CSR and the private key:

openssl req -nodes -newkey rsa:2048 -nodes -keyout dotmarks.net.key -out dotmarks.net.csr -subj "/C=GB/ST=London/L=London/O=dotmarks/OU=IT/CN=dotmarks.net"

Generates

• dotmarks.net.key
• dotmarks.net.csr
