Maybe you aren't a political dissident engaging in top secret conversations over text messages. But if you care about privacy, you should probably be using Signal—or really, another encrypted service—to send your messages. Encryption can be a hot-button issue, with governments demanding backdoors into private data stores and executives at companies like Facebook having wildly different opinions about how secure your communications should be. Plus, at a time when we're relying more and more on digital services to talk with each other, it's important to know who has access to your conversations.

This week on Gadget Lab, WIRED digital director Brian Barrett joins us to talk about the ins and outs of encryption, and why you'd want to use a secure messaging service in the first place.
