It's always a good day when we can talk about cryptography. Especially when we are sunsetting one of the oldest and most important encryption algorithms in Tor and replacing it with a research-backed new design, called Counter Galois Onion. This overhaul will defend users against a broader class of online attackers (described below), and form the basis for more encryption work in the future. Which cryptography are we talking about here? The algorithm in question is Tor's relay encryption. While ...
