In preparation for a Trump-led NSA, we’re making our tiny contribution to online security.
The result of encryption is that any onlooker who lacks our secret keys would see us carrying on an undecipherable conversation. Kind of like a secret Pig Latin. They wouldn’t know what articles you clicked on or comments you made.
Normal web traffic — that is, web traffic that isn’t secure — passes in a plain and easy-to-read fashion through various intermediaries. This could include, say, any nosy people using the same public Wi-Fi connection as you, the manager of that Wi-Fi hub, an Internet Service Provider and any other connections your traffic passes through (which very likely includes major exchanges in the heavily surveilled United States, even if both you and the website you’re visiting are based in Canada.)
