Arti 2.5.0 released: Stable Counter Galois Onion | Tor Project

Tor has fixed their long standing tagging attack, improved forward security, and added sufficient authentication. See the Arti 2.5 stable release announcement too, as well as 2025/583, 2025/2017, and tor spec 359.

"Jean Paul Degabriele, Alessandro Melloni, Jean-Pierre Münch, and Martijn Stam have a design that they're calling Counter Galois Onion (CGO). It's based on a kind of construction called a Rugged Pseudorandom Permutation (RPRP): essentially, it's a design for a wide-block cipher that resists malleability in one direction (for the encrypt operation, but not the decrypt operation). If we deploy this so that clients always decrypt and relays always encrypt, then we have a tagging resistant cipher at less cost than a full SPRP!"

Like Outta The Toilet?

via r/collpase but they delete everything, so fresh post not a repost, and r/collapze would be the better subreddit overall

Leslie Fish - Lucifer

73k views vs 2.5m views for The Alan Parsons Project track, and 4m for Jay-Z, and 10m for Eminem, and who knows what else.

Leslie Fish was perhaps the strongest r/filk lyricist to date. "Her song Hope Eyrie is regarded by some as being as close to the anthem of American science fiction fandom as is possible in such a disparate group."

The album Avalon Is Risen has a bunch of nice fantasy filk songs, like Berserker and The Sun is Also a Warrior.
