How can we help with getting support for Ed25519 in crypto/x509 and crypto/tls?

Not possible yet, but I have some ideas.

Our followup Karaoke system [1] can support more users by adding more servers, but we still have more work to do to support billions of users. Regardless, I think it's worth deploy…

It doesn't yet. I'd like to integrate Karaoke's techniques into the Vuvuzela client in the coming months.

Thanks. I just added our latest paper to the list.

Sorry! We signed and uploaded new configs, so it should be working now.

Sorry about that. I need some way to prevent someone from quickly registering many email addresses. Do you have any other ideas?

Our latest paper, Karaoke, achieves 6.8 seconds with 2 million active users: https://vuvuzela.io/static/karaoke.pdf

Nice! Looks similar to Seal [1] (also written in Go). I just added a link to Pick under related work. [1] https://github.com/davidlazar/seal

I used pwclip [1] for several years but I no longer believe that hash-based password managers are the best plan. Now I'm using Seal [2], which is like pass but doesn't depend on gp…

We measured 10% improvement on ppc64.

The compiler got a bit slower: https://github.com/golang/go/issues/19386 Those numbers are just for my CLs that fix stack traces but with mid-stack inlining still off. Turning it o…

The plan is to add inlining information to the DWARF tables so that debuggers and other tools can take advantage of it.

Only temporarily. I'm interning on the Go team, but still working on Vuvuzela and Alpenhorn in my spare time.

Author here. I've been working on a follow-up system called Alpenhorn that addresses the bootstrapping problem in Vuvuzela: https://vuvuzela.io/alpenhorn-extended.pdf I will releas…

I built flycrypt as a highly simplified PGP based on NaCl. I've used it to send credit card numbers and passwords over email. https://github.com/davidlazar/flycrypt

We're using noise to hide metadata in the Vuvuzela messaging system [1]. Using noise to hide metadata is efficient and gives good privacy (better than Tor-based approaches). We've …

The slides toward the end of my talk [1] try to give some intuition for Vuvuzela's security in terms of "jury certainty". [1] https://davidlazar.org/slides/vuvuzela-sosp2015.pdf

Author here: The latency can be reduced by future work. For example, Section 9 in the paper mentions an idea for reducing the amount of noise (and thus reducing latency) by treatin…
