Complexity in quantum simulator
Hi! I was recently reading about Grover's algorithm. Whil I do understand that the overhead of quantum computing and quantum simulation greatly outweight the time complexity benefit compared to traditionnal bruteforcing(at least for now), it got me wondering: Theoretically, would running grover's algorithm on a quantum simulator still have sqrt(N) …
Wire broadly migrated to MLS
[Messaging Layer Security](https://messaginglayersecurity.rocks/) (MLS) is an [IETF](https://datatracker.ietf.org/wg/mls/about/) [standard](https://www.rfc-editor.org/rfc/rfc9420.html) for end-to-end encryption (E2EE) which supports larger groups and multiple devices better than the sender keys protocol used in Signal ([WG github](https://github.com/mlswg/), [previously](https://www.reddit.com/r/crypto/comments/8o2g3y/google_inria_mozilla_mit_twitter_and_wire_are/), [wiki](https://en.wikipedia.org/wiki/Messaging_Layer_Security)). Wire was quite involved in the WG. The RCS standard has [added optional support for MLS](https://www.ietf.org/blog/rcs-adopts-mls/) too, or …
What's with the lack of adoption of Curve448?
Why don't many standards and software projects support Curve448 yet? Support for Curve448 (and Edwards ECC in general) in X.509 is still quite poor. [There was an RFC created in 2018 for it](https://datatracker.ietf.org/doc/html/rfc8410), but it's still listed as a "proposed standard" - and, practically speaking, you cannot get EdDSA certificates. …
