Security Cryptography Whatever
Some cryptography & security people talk about security, cryptography, and whatever else is happening.

Trump's Golden Post-Quantum EO(s)
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!Watch on YouTube: https://www.youtube.com/watch?v=7ZwQpN_F6P8Transcript: h

AI Finds Vulns You Can't With Nicholas Carlini
Returning champion Nicholas Carlini comes back to talk about using Claude for vulnerability research, and the current vulnpocalypse.

Standardizing Pure PQC
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
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 woul
The IACR Can't Decrypt with Matt Bernhard
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
Apple’s Memory Integrity Enforcement
Apple announced its new suite of memory security improvements from the top of the stack all the way to the bottom, so we dug through what they did and how they did it (performantly).

Stop Using Encrypted Email with William Woodruff
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.Watch on YouTube: https://www.youtube.com/watch?v=IoL3LfIozJoTranscript: https://s

Vegas, Baby!
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 th
E2EE Storage Done Right with Matilda Backendal Jonas Hofmann and Kien Tuong Truong
It seems like everyone that tries to deploy end-to-end encrypted cloudstorage seems to mess it up, often in new and creative ways. Our specialguests 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.Watch on YouTube: https://youtu.be/sizLiK_byCwTranscript: https://security
Picking Quantum Resistant Algorithms
Migrating the US government to quantum-resistant cryptography is hard, luckily the gamer presidents are on it.

Apple Pulls Advanced Data Protection in the UK with Matt Green and Joe Hall
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.
