    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 would be moving away from OpenSSL when supporting new functionality and exploring adding other backends instead. We invited them on to tell us about what has happened to OpenSSL, even after the investments and improvements following Heartbleed. No guests on this pod represent anyone besides themselves.

    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 not.

    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.

    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?

    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 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.
