As I’ve mentioned in the past, I’m a big fan of the FriendlyId gem for easily creating human-readable, search engine-friendly URLs. But what if you want to make something that’s not so human or search engine friendly? Here’s one simple way to get something up and running.
For this demonstration, I’ll be using the FriendlyId gem’s ability to use a custom method for a slug. (I’m assuming you’ve installed and configured FriendlyId as dictated by the gem’s instructions.) What I’m doing here is creating a SHA1 hash of a secret’s
name field. You could, of course, use any unique field that’s not going to change (though FriendlyId should remember old slugs, if necessary), or use your own encryption technique.
Like I said, it’s simple. If your security needs are serious you’d probably want something a little more complex (not to mention more layered than a basic obfuscation technique), but I wanted to share an out-of-the-box way to use a gem that already exists (and may even be in use in your app already).
I stand with the Black community against systemic racism, police violence and brutality, intolerance, and hate in the United States and worldwide. We must all demand better from our leaders, and ourselves. Stop tolerating intolerance.
