It seems like everyone that tries to deploy end-to-end encrypted cloud storage seems to mess it up, often in new and creative ways. Our special guests Matilda Backendal, Jonas Hofmann, and Kien Tuong Truong give us a tour through the breakage and discuss a new formal model of how to actually build a secure E2EE storage system.

Just a few days before turning off the lights, the Biden administration dropped a huge cybersecurity executive order including a lot of good stuff, that hopefully [cross your fingers, knock wood, spin around three times and spit] will last into future administrations.
