In the last few years phones and apps have been touting themselves as better than other phones/services because their messaging has end-to-end encryption, or some other variant of secure messaging. Why do we care?

End to end encryption works like this: you give everyone in the world a way to lock messages they send to you, and you have a way to lock messages you send to them. When locked only the intended recipient can unlock te message and read it.
Something important to remember about messages sent over the internet is that anyone can potentially see and read them without you knowing (as apposed to an envelope which you can usually tell was opened) so you need other ways to be sure that other people haven’t intercepted your messages.
