In my opinion questions about PKI and key management are better asked at the IT Security site; that is: if they are mainly concerned about management (company rules, expiration dates etc). If they are …

If I take a look at our Tour this crypto site is for questions about: Asymmetric and symmetric cryptographic algorithms Cryptographic protocols and cryptanalysis techniques Hashing Entropy and infor …

Would it be approbate to rewrite the body of the question to more specifically ask for the motivation of RSA-OAEP, what it does, and why? No, that would alter the meaning of the question. Such ch …

Yes, you are allowed to post code to illustrate a question. Preferably this code is easy to understand. Pseudo-code could be better for this, as any API/language has hard to understand constructs to t …

No, it would not be on topic for two reasons: StackExchange acts as a question / answer site and knowledgebase. However, requests for consultancy are not on topic. These kind of "questions" commonly …

No, this is on topic on the main site, cryptography. If asking for descriptions of cryptographic primitives is OK, then I don't see how asking for graphic representations isn't. That said, just askin …

You may or may not have noticed that BitCoin.SE and Ethereum.SE have narrowed their scope. Nowadays that means that they only accept questions that are about their specific crypto currency and block c …

Some tools are so specific to crypto that it may well be that this Q/A site has the best knowledge about those tools. These are mainly tools for crypt-analysis such as tools to test randomness or tool …

As we know, cryptanalysis questions are off-topic here - there's little value of a single decrypted plaintext to the larger community Cryptoanalysis is generally thought of as the analysis of crypto …

I think it is pretty obvious that questions that are just about CRC are not on topic here. The problem is of course that it would not even be clear to me where they should belong. Definitely not on ma …

Mark the question as "too broad" or "primarily opinion based" as recommending "good" books / courses is clearly subjective, and listing all of them is ridiculous (and can be had simply by hitting "cry …

About this particular question The code you published is an attempt to replicate test vectors, and failing. Most likely this is because of an implementation mistake or a error in trying to convert th …

I'm voting to close this question as off-topic because we already have an "off-topic -> other" close reason. This is the generic close reason, but you still have to specify why the question is off top …

Generally they are not, unless they are explicitly about the cryptographic algorithms used to implement the NFT. If they are about the general security you could ask on IT Security. If they are about …

We've got an upcoming close reason about cryptocurrency sites. However, instead of closing down questions we may want to migrate them or point out the resource to the user. That's more helpful than cl …
