As a clarification for how this works: This election determines a new full-fledged moderator. Elections are for life-time. If a moderator steps down (in good standing) they can be reinstated again without a full election (following a defined process).

@bdegnan well, you could run for it anyways and let the voters decide whether they want you or one of the other candidates?

FYI: I have requested a new moderator election to find my successor. This is fully happening on good terms with everyone involved and there's no drama to be found here. I'm stepping down essentially because I no longer find myself spending much time on Crypto.SE and believe that it's not sensible for such a person to be a moderator. Thank you all for electing and supporting me as a moderator though <3 I will also post a message like this below the election announcement.

Q: Does Schnorr's 2021 factoring method show that the RSA cryptosystem is not secure?

TeamBrightClaus Peter Schnorr recently posted a 12-page factoring method by SVP algorithms. Is it correct? It says that the algorithm factors integers $N \approx 2^{400}$ and $N \approx 2^{800}$ by $4.2 \cdot 10^{9}$ and $8.4 \cdot 10^{10}$ arithmetic operations. Does this lead to the conclusion that the R...

Q: The future of Community Promotion, Open Source, and Hot Network Questions Ads

JNatIt's now May, and if Community Promotion or Open Source Ads are something you care about, you may have noticed that there hasn't been a 2021 refresh yet.

Q: What does it mean for “1^n”(i.e., the security parameter written in unary)?

涂新宇As it is mentioned above, I am confused about “Gen takes as input $1^n$ and outputs a key“. Does it mean that the input of Gen is 1111....111 with length of n?

Q: Testing three-vote close and reopen on 13 network sites

CatijaAlmost two years ago I ran a test for single vote closure/reopen on Hardware Recommendations after one of their moderators reached out to me about the strain of being the person doing most of the work to close questions on that site. Shortly after that, Shog9 ran a three-vote test on Stack Overfl...

A: Do we want to update our "Ask Question" side-bar and if so, how?

SEJPMI agree with the more exhaustive proposal initiated by kelalaka that a bulleted list might be helpful. However, I think we should keep it contained to the most common issues we encounter and leave the exhaustiveness to our Help Center. So instead my below suggestion focuses on our four close reas...

@bdegnan there are contexts where it is only used as a n-out-of-n secret sharing scheme, in what contexts did you encounter it?
SEJPM
Apr 15, 2021 18:30
@bdegnan ^ what Aman said, the point of shamir secret sharing is to literally provide k-out-of-n threshold secret sharing

what you could probably do is copy the state after the update step, finalize the copy and send the hash falling out of that, continuing to update the "original" state
SEJPM
Apr 9, 2021 18:20
the best illustration for how hashes process data is typically that you initialize state, then update state (which either buffers the input or triggers a compression call with the buffer and the state) and then a finalization step
SEJPM
Apr 9, 2021 18:18
asserting that everything seen so far is correct according to the received hash?
SEJPM
Apr 9, 2021 18:18
@bdegnan so you want some kind of "intermediate tags / hash" where the intermediate hash state is inserted into the stream?

A: Can We get a Fourth Custom Close Reason Slot for Cryptocurrency Questions?

CatijaIt definitely looks like y'all need some help disambiguating cryptography from cryptocurrency and this seems like a good place to start - that said, this still requires that y'all do the work of closing the questions after the fact. I'd suggest y'all take some time to craft more customized text f...

I'm currently writing a thing about accelerating things with better AES implementations. Given my previous answer (mattermodeling.stackexchange.com/a/1682/1128) it seems matter modelling people do a lot of randomized simulations requiring lots of random numbers. Do you guys by chance have a default paper to reference for such things?
