  An Odyssey of Lattice Cryptography with Mark Schultz-Wu 27.07.2026 1h 17m

  We invited Mark Schultz-Wu on the podcast to talk about the history of lattice cryptography. When lattices are explained in plain english, they are actually quite simple! I don't think any of us have ever seen Deirdre so happy. If you're watching the video version, there's a section that's 6.1 minutes long with no cuts and consists just of Deirdre vigorously agreeing with what Mark is saying while smiling. What a time to be alive. Anyway, we are hosting another happy hour in Vegas between Bla...

  Trump's Golden Post-Quantum EO(s) 02.07.2026 56m

  The dear leader has actually bleated out some not-dumb executive orders (EOs) to accelerate adoption of post-quantum crypto for the US government! This looks to be in response to a flurry of advancements in quantum computing and quantum attack algorithms a few months ago. We cram legalize into our eyeballs— plus, ECDSA.fail!

  AI Finds Vulns You Can't With Nicholas Carlini 25.03.2026 1h 16m

  Returning champion Nicholas Carlini comes back to talk about using Claude for vulnerability research, and the current vulnpocalypse. It's all very high-brow stuff, and the gang learns some bitter lessons.

  Standardizing Pure PQC 09.03.2026 8m

  Standardizing cryptography involves a lot of opinions. Luckily, the gamer presidents are on it. Come on, you all know the drill. This is the last time I do this. "Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@dadrian)

  Python Cryptography Breaks Up with OpenSSL with Paul Kehrer and Alex Gaynor 01.02.2026 1h 12m

  The Python cryptography module, pyca/cryptography, has mostly been a sane wrapper around a pile of C, so that users get performant cryptography on the many, many platforms Python targets. Therefore its maintainers, Alex Gaynor and Paul Kehrer, have become intimately familiar with OpenSSL. Recently, they declared that after many years of trying to make it work, they announced pyca/cryptography would be moving away from OpenSSL when supporting new functionality and exploring adding other backen...

  The IACR Can't Decrypt with Matt Bernhard 30.12.2025 56m

  The International Association of Cryptologic Research held their regular election using secure voting software called Helios…and lost the keys to decrypt the results, leaving them with no choice but to throw out the vote and call a new election. Hilarity ensues. We welcome special guest Matt Bernhard who actually works on secure voting systems to explain which bits are homomorphically additive or not.

  Stop Using Encrypted Email with William Woodruff 22.08.2025 1h 11m

  There was a bug in an OpenPGP library which finally gave us an excuse to tear encrypted email via PGP to shreds. Our special guest William Woodruff joined us to help explain the vuln and indulge our gnashing of teeth on why email was never meant to be encrypted and how other modern tools do the job much, much better.

  Vegas, Baby! 29.07.2025 1h

  We’re throwing a party in Vegas! Someone called it SCWPodCon last year, and the name stuck. It’s sponsored by Teleport, the infrastructure identity company. Get SSO for SSH! If Thomas was here, I’m sure he’d tell you that Fly.io uses Teleport internally. Oh also there's some thing called Black..pill? Black Pool? Something like that happening in Vegas, with crypto talks, so we chatted about them a bit, plus some other stuff SCWPodCon 2025: https://securitycryptographywhatever.com/events/black...

  E2EE Storage Done Right with Matilda Backendal Jonas Hofmann and Kien Tuong Truong 19.05.2025 1h 2m

  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.

  Picking Quantum Resistant Algorithms 23.03.2025 14m

  Migrating the US government to quantum-resistant cryptography is hard, luckily the gamer presidents are on it. This episode is extremely not safe for work, nor does it reflect the political opinions of, well, anybody.

  Apple Pulls Advanced Data Protection in the UK with Matt Green and Joe Hall 24.02.2025 48m

  Apple has pulled the availability of their opt-in iCloud end-to-end encryption feature, called Advanced Data Protection, in the UK. This doesn't only affect UK Apple users, however. To help us make sense of this surprising move from the fruit company, we got Matt Green, Associate Professor at Johns Hopkins, and Joe Hall, Distinguished Technologist at the Internet Society, on the horn.

  Biden’s Cyber-Everything Bagel with Carole House 20.01.2025 57m

  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. We snagged some time with Carole House, outgoing Special Advisor and Acting Senior Director for Cybersecurity and Critical Infrastructure Policy, National Security Council in the Biden-Harris White House, to give us a brain dump...

  Dual_EC_DRBG with Justin Schuh and Matthew Green 07.12.2024 1h 7m

  Nothing we have ever recorded on SCW has brought so much joy to David. However, at several points during the episode, we may have witnessed Matthew Green's soul leave his body. Our esteemed guests Justin Schuh and Matt Green joined us to debate whether `Dual_EC_DRBG` was intentionally backdoored by the NSA or 'just' a major fuckup.
