Since the last time Peikert was on, Michigan football and Michigan basketball both won a national championship. That's the new bar for repeat guests.
NEW EPISODE! Lattices! New complexity results in the closest vector problem & a possible poly-time quantum attack against the dihedral coset problem that made everyone freak out for about a week; ALSO there's a distinguisher attack against Classic McEliece 😱 youtu.be/7_Db0LXQrk0
I wrote a post about how security undervalues preventing problems, and how this can be exasperated by AI and the vulnpocalypse, even though AI should actually make robustness much easier for defenders. Read it here: dadrian.io/blog/posts/w...

securitycryptographywhatever.com/2026/03/25/a... is very very good. If you read my vulnerabilities post, this podcast episode is much more worth listening to.
New episode! We talk to @lcamtuf.coredump.cx about the vulnpocalypse. www.youtube.com/watch?v=uI9C...
I poked around with @exe.dev some, and wrote up how I think their Github integration works, because it's pretty cool. dadrian.io/blog/posts/e...

NEW EPISODE! The maintainers of py/cryptography declared that after many years of trying to make it work, they would be moving away from OpenSSL when supporting new functionality and exploring adding other backends: securitycryptographywhatever.com/2026/02/01/p... www.youtube.com/watch?v=dEKB...

This is what zero-trust looks like at the infrastructure layer. Identity and encryption match the lifetime of the thing being secured. If your certificate strategy still assumes stable names and year-long validity, it is already behind reality. letsencrypt.org/2026/01/15/6...

Final SCW of 2025! We had Matt Bernhard on to talk about cryptographic voting systems, in the wake of the IACR election. (Everybody I voted for in the new election won! Woo!)
NEW EPISODE! The IACR lost the keys to decrypt their encrypted election results. We welcome Matt Bernhard who works on secure voting systems to explain which Helios bits are homomorphically additive or not and more: securitycryptographywhatever.com/2025/12/30/i... www.youtube.com/watch?v=euw_...

It's time to make HTTPS the web's default, and reap the full security benefit from years worth of HTTPS adoption! security.googleblog.com/2025/10/http...
One year from now, Chrome will enable "Always Use Secure Connections" and warn users before plaintext HTTP by default.
New post! Stop trying to solve revocation, we already have the answer. dadrian.io/blog/posts/r...

The bigger issue? Microsoft’s root program still trusts this CA, leaving Edge and Windows users exposed in ways Chrome, Firefox, and Safari users aren’t. The pattern is familiar: long-lived trust, weak oversight, systemic risk. It’s time for Microsoft to step up and fund proper root governance. 👇
