So I don't do #Java for a reason, but trying to get a #pqc client speaking X25519MLKEM768 using BouncyCastle took me overriding the keyshare extension manually, and that can't be right.

Any Java folks out here able to tell me that that's stupid and how to do it the right way?

At Akamai, we're launching a blog post series on various topics relating to post-quantum cryptography. The first post is by @rsalz, discussing some related IETF initiatives, including the two #TLS drafts he co-authored:

Hello, I’m hosting a #Vaultwarden server behind #Caddy 2.10 and made the following test:

Tuning Caddy to allow only #PQC curves:

	tls {
		curves x25519mlkem768
	}

Trying to connect with #Firefox Mac -> OK
Trying to connect with #Bitwarden #android client -> Fail

Without the #TLS tuning, the Bitwarden Android client will happily connect to the server.

Is it a problem with the Bitwarden Android client or with Android, or both?

Lorenz Panny gave a talk on Isogeny-Based Cryptography at the PQCSA Summer School in Albena, exploring one of the most mathematically rich areas of PQC.

The IETF working group that I co-chair, PQUIP, had its first RFC published today. RFC 9794, "Terminology for Post-Quantum Traditional Hybrid Schemes", lists and describes terms used in post-quantum cryptography that are specific to the hybrid schemes that have become the focus for much of the PQC development work.

In short hybrid schemes are those that fully mix both post-quantum and traditional asymmetric algorithms. There are a lot of ways to mix them (some better than others), and thus there are a lot of properties that different mixtures have. The result is a lot of potentially confusing vocabulary full of similar-looking four-word chains. This document lays out all the differences so that other groups (other IETF working groups, other standards development organizations, governments making standards, ...) can be precise about what schemes they are adopting and why.

Congrats to the WG and the RFC authors!

Now we have a press release from Toshiba and Orange announcing the world’s first commercial #quantum safe network offering, combining #QKD and #PQC. Haven’t been able to read the tech specs yet but it’s now available in the Paris metro area, and already has a financial services customer.

The pace of innovation in this space is constantly accelerating.
