Yes, gimme hats! I think Crypto.SE - as a community - should participate in the winter bash 2016. Individual users who don’t want to participate, don’t want to see hats, and/or are generally anti-hat will have an “I hate hats” option available.

Squeamish, you will be sorely missed. You've been the most prolific but also one of the best contributors to this site with regards to quality. Feel free to return to the site at any time. Or to the side channel of course, if you feel like talking to any of us. As for the politics of the site: I can feel the frustration myself too, and I have often ...

How about "The Side Channel"? (Besides being a recognized crypto term, as well as descriptive of chat as a secondary communications channel, it's also somewhat appropriate — in a silly punnish way — because a link to the chat room is typically shown in the sidebar on the main site. Or, at least, it would be shown if we actually had people ...

Since I figure Meta is a bit 'free', I'll put this comment here for its own discussion: Often, these occurrences seem to follow the structure of: Ambiguous/gibberish claim with a "aren't I brilliant?" line to make it a question. A hardworking user cleans it up (usually e-sushi!) Someone answers the question by demonstrating why the "breakthrough" is ...

The "Analyzing/Deciphering Data" + "Peer Review" Combo Message off-topic – Requests for analyzing ciphertext or reviewing full cryptographic designs are off-topic, as the results are rarely useful to anyone else and/or would be too long for this site. Code Requests for [analyzing ciphertext](https://crypto.meta.stackexchange.com/q/100) or [reviewing full ...

What should we do with no-effort homework dumps? Close. We are doing a disservice to the students by doing anything else. There are also ethical issues here. Should we treat questions with effort shown differently? Yes, give them hints, but make sure not to solve for them. Should we want to deliver full answers or merely hints? How should hints be ...

I tried e-sushi's design with a different background: (If anyone wants to play with it, here's the background image by itself) (Edited to add vignette to background. Check the edit history for the previous version.)

Let such answers stay (at the discretion of the poster) if they're not blatantly not answering the question. That is, if an answer even partially answers the question, exclusively using conspiracy theories, it shall stay and be left to down-votes. Not-An-Answer and similar flags on these answers will then be mostly declined. More detailed explanations can ...

My opinion is that "SSL" and "TLS" are not to be opposed. TLS is the standard acronym for a standard protocol, published by IETF as a "Standards Track" RFC; it now covers three protocol versions (TLS 1.0, 1.1 and 1.2) that are quite similar to each other. On the other hand, "SSL" is a loose designation for three ...

…sometimes feels that I'm the only person voting it up. Trust me, I know the feeling. ;) /* Just check our main site voting stats and our meta voting stats to see the top-10 voters. */ I especially don't get it when a person answers a good question but still doesn't upvote it. Maybe the answer occupies all the brain cells required to upvote… Personally,...

Do we want bitcoin/cryptocurrency related questions? Questions about the cryptographic mechanisms are fine, questions about economy, usage, acquisition, ... are not! What we do with the questions of the latter kind depends on the exact instance. If the question is of poor quality to begin with and can't / won't be salvaged by edits, then closing / deleting ...

This is probably the nicest Christmas present we could get from StackExchange/StackOverflow. Thank you for your brilliant creativity, Pawel – I bet I’m not the only one thinking “I love it!”.

I see three options to promote such events. Make a meta post. Make a post here on meta documenting the existence of this event and briefly summarize what it is about, where and when it is. You may also ask our mod team (via chat or comments) for the featured which will make the post pop up on the main site. This is especially practical if you have a medium ...

The comment denigrating the OP for asking a question was out-of line if it was as described in the comments. However, the other one seems fine. I do not think we should assume the asker lacks mathematical background. That can seem at least as rude as the converse if the assumption is incorrect. Instead, any answer will necessarily assume some level, which ...

No rijndael was what later became aes, but there are specific differences between both. Those differences surely justify both tags to exists next to each other. If only, as it might help users find answers to Rijndael-specific questions easier. Making one a synonym of the other would be rather non-constructive from that perspective.

We don't provide a list of the logos for every single one of our sites in any accessible place. However, all of our logos are saved and loaded in an SVG format on-site, so you could easily just download the sprites file from the site and extract the logo out of it in an essentially-vectorized format. We generally don't care if you print a shirt for your own ...

Side-Channel attacks and their mitigations are on-topic. The above is the line I would draw. If answers to questions on the above require digging into code / how compilers (likely) do some things, so be it. The above guide-line also covers the specific question because in the first discussed sub-question it is explicitely asked "(how) does this 'atomic ...

Wow. I'm not sure what to say. I guess the usual thing people say in these situation is "thanks". So I shall do the same. I would like to thank everybody who has put the faith in me to be a good moderator for Crypto.SE. I shall do my best not to disappoint all of you! I would like to thank the current / "old" moderator team for having ...

Before reading this, please be warned that my feedback is going to hurt some feelings. Honestly, and please excuse my choice of wording, the new theme sucks big time! The left sidebar – which merely contains some links and had a perfect place at the top - is now being rendered into a huge waste of screen space. Not only doesn’t it push the important ...

Should we allow generic questions about block chain? If it's about cryptography, yes. For example, How did the signature malleability flaw in Monero work?, or What is the impact of quantum computers on the Bitcoin blockchain?, or How is the “Keccak-256” function used in Ethereum different from SHA-3?, or What are the security requirements for the hash ...

As suggested by PyRulez… SVG resource etc. available at github.

I believe we should be a bit flexible about that and determine it on a case-by-case basis. In particular, we should think whether or not cryptographic expertise is required to make use of the tool. If not, then it would be fine sending it to another site for general system administration. This would include, for example, asking how to import a keyring into ...

Programming Questions Programming questions are off-topic even if you are writing or debugging cryptographic code. Unless your question is specifically about how the cryptographic algorithm, protocol or side-channel (mitigation) works, you should look into asking on Stack Overflow instead. When to use: Use this whenever a question should either be migrated ...

Here are our current policies: We keep a question (i.e. as a user upvote it if it's good) when there's a reasonable interpretation of it that uses a minimal amount of code only to illustrate a point, e.g. to describe a reasonably simple cryptographic scheme. Alternatively we keep a question if it is about side channel attacks or their countermeasures, as ...
