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. It's all very high-brow stuff, and the gang learns some bitter lessons.Watch on YouTube: https://www.youtube.com/watch?v=_IDbFLu9Ug8Transcript: https://securitycryptographywhatever.com/2026/03/25/ai-bug-finding/Links:- https://red.anthropic.com/2026/zero-days/- https://unpromptedcon.org/- Black-hat LLMs  - https://red.anthropic.com/2026/firefox/"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@dadrian)

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 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.Watch on YouTube: https://www.youtube.com/watch?v=dEKBHI3rodYTranscript: https://securitycryptographywhatever.com/2026/02/01/python-cryptography-breaks-up-with-opensslLinks:- https://cryptography.io/en/latest/statements/state-of-openssl/- Py Cryptography: https://cryptography.io- https://archive.openssl-conference.org/2025/presentations/Alex_Gaynor_Paul_Kehrer_The_Python_Cryptographic_Authoritys_OpenSSL_Experience.pdf- https://securitycryptographywhatever.com/2025/08/16/alex-gaynor/- https://packages.gentoo.org/packages/media-libs/libsdl- https://www.youtube.com/watch?v=RUIguklWwx0- https://datatracker.ietf.org/doc/rfc9180/- https://docs.openssl.org/3.3/man3/OSSL_PARAM/- https://openssl.foundation/- https://github.com/openssl/openssl/issues/17064- https://www.feistyduck.com/newsletter/issue_132_openssl_performance_still_under_scrutiny- https://github.com/topazproject/topaz- https://github.com/actions/runner/issues/1069- https://crystalhotsauce.com/- https://openssl-library.org/news/vulnerabilities/#CVE-2025-15467- https://en.wikipedia.org/wiki/Ship_of_Theseus- https://boringssl.googlesource.com/boringssl/+/aa202db1d7091b88b80f0a58c630c5c1aefc817d- https://www.ibm.com/products/open-sdk-for-rust-aix- https://dadrian.io/blog/posts/corporate-support-xz/- https://peps.python.org/- https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ed448/- https://go.dev/blog/fips140- https://dadrian.io/blog/posts/roll-your-own-crypto/"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@dadrian)

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.Watch on YouTube: https://www.youtube.com/watch?v=euw_yqAQFI8Transcript: https://securitycryptographywhatever.com/2025/12/30/iacr-heliosLinks:- NYT: https://www.nytimes.com/2025/11/21/world/cryptography-group-lost-election-results.html- IACR Memo: https://www.iacr.org/news/item/27138- https://www.iacr.org/elections/- https://vote.heliosvoting.org/faq- https://github.com/Election-Tech-Initiative/electionguard- https://www.usenix.org/legacy/events/sec08/tech/full_papers/adida/adida.pdf- https://www.iacr.org/elections/eVoting/about-helios.html- https://www.iacr.org/elections/eVoting/- https://crypto.ethz.ch/publications/files/CrGeSc97b.pdf- https://electionguard.vote/- https://eprint.iacr.org/2025/1901- https://freeandfair.us/blog/open-free-election-technology/- https://www.starvoting.org/- https://mbernhard.com/"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@dadrian)
