A bunch of people have been curious about how to set up DRb to work over SSL. Since I've not seen any pointers to an authoritative document on how to do this, I went out and investigated on my own.
Heading out to Google, I found NAKAMURA Hiroshi's (NaHi) post [ ruby-talk:89917 ] that detailed this extensively, but was just too cumbersome to put into a friendly, easily digestible document.
I found that using getting DRb to use SSL is really, really easy, but getting the required SSL certificates is rather painful.
So I took NaHi's code and explanation for generating SSL certificates and wrapped them up into QuickCert for generating SSL certificates from a simple configuration file, then I wrote a document describing how to use DRb over SSL.
Other than putting all the SSL certificate generation into a shrink-wrapped package, all the groundwork was done by NaHi.
