In a move that’s bound to make spies everywhere a tad jealous, Tor unveils Counter Galois Onion (CGO)-the shiny new encryption armor for your relay traffic, because apparently, just a good old hat isn’t enough anymore.
On a mysteriously significant date-November 24, 2025-Tor decided to play Santa, gifting itself (and by extension, you) with CGO to fend off tagging attacks, bring forward secrecy (fancy term, basically “your secrets stay secret”), and to make relays feel modern, brave, and just a tad faster. Implementation? Somewhere between “working miracles in Rust” and “C Tor is fuming.” Development? Oh, just refactoring relay cell handling and playing with experimental gadgets in Arti. Nothing big, really.
CGO has adopted something called Rugged Pseudorandom Permutation (RPRP)-which sounds like something from a superhero comic-using the UIV+ system that’s basically a vault door for your data, chaining tags and nonces to resist tampering, and replacing the old 4-byte digest with a hefty 16-byte authenticator-because size does matter. The goal? Prevent covert channels, stop your relay traffic from whispering secrets, and make sure even if someone sneaks a peek, they see nothing but confusion.
Next steps? Enabling CGO in Arti by default (because why not jump into the deep end?), possibly negotiating with onion services (probably just Arti, because it’s standing in the corner looking smug), and tuning those hyper-modern CPUs for maximum speed-because fast is just slow enough.

🧭 FAQs
• What is Counter Galois Onion and when did it make its debut? It’s a shiny new relay encryption that announced its arrival on November 24, 2025-because who doesn’t love a future-proof onion?
• Which Tor versions will support CGO, and is your jurisdiction safe? Arti (Rust) and C Tor will be the lucky recipients-applicable wherever Tor is used, so basically everywhere, including your secret underground lair.
• How does CGO safeguard Tor users lurking in local networks? It prevents tagging attacks (because your traffic shouldn’t be giving you away), adds forward secrecy (no peeking into the future), and beefs up authenticators (because even your secrets deserve a sturdy lock).
• When will Arti turn on CGO by default, and what’s next on the to-do list? Once the testing gods give the thumbs up, Arti will enable CGO, then move on to negotiate onion services (probably with a nod and a wink) and squeeze performance out of CPUs like a lemon on a hot summer day.
