How to Generate a DSA signature?

Question

I'm using Sparkle in my Application to do updates but in the documentation it says to generate a DSA Signature and provides a tool to do is (the tool is coded in ruby) but i don't know how to use it. Can someone help?

This is where the documentation is (Step 3): http://sparkle.andymatuschak.org/documentation/pmwiki.php/Documentation/BasicSetup?from=Main.HomePage

Answer 1

Google'd the command string, and got a handful of hits.

Quoting the author:

It's a script; you need to run it from the command line.

Open the terminal. Change into the Sparkle distribution directory. Type:

ruby "Extras/Signing Tools/generate_keys.rb"

Follow the instructions on the wiki from there.

Also, I'd highly recommend looking at Feeder for constructing your Sparkle RSS feed. It can generate a DSA signature for you automatically, once you drag your binary into an update entry. It also can upload your binaries and feed to your server for you. Overall, it's saved me a tremendous amount of time with my Sparkle feeds.
