Encryption is one of the few things that can be relied upon to keep data safe. One of the things that the Citizen Lab has argued for repeatedly is the availability of what's called end-to-end encryption. It's encryption where a message is secured from your device, goes to someone else's device, and only the two parties can access it. That's especially important as we see more and more systems move to the Internet, because it ensures that when and if the network is compromised, whoever is compromising the network can't gain access to the communications that are transmitted across it.
