I think that:

  • Tags and should be merged to . In my opinion having special tag for SHA-256 doesn't actually make sense.

  • should be renamed to as we don't curretly have questions talking about SHA as about family of hashing algorithms. All of them refer to specific versions.

Actually, since this is a security site, and I expect almost any algorithm-specific question to be on the Cryptography site instead of here, I personally think we shouldn't even have any algorithm-specific tags, at all.

Rather, I would instead of both and , I would retag them both as ; I would do the same for and . Same with .

I would do the same for encryption algorithms, too - e.g. instead of and simply have , or possibly .

My point is, most of those questions either: (a) should be asked on crypto, because it is about the algorithm details; or (b) mostly irrelevant which algorithm is used, from a security management point of view; or (c) apply to a range of algorithms, or the specific algorithm is not known in the question (e.g. which algorithm to use in a specific situation).

    Algorthmic tags may exist as there are questions about how to correctly use those algorithms. Usage of crypto is a topic of security.SE. Crypto internals is a topic of crypto.SE Oct 5, 2012 at 15:24

    I do understand where AviD is coming from. Looking through the various questions tagged as sha or sha256, they all can fit into the hash tag.

    And considering the low volume of questions tagged with that compared to the generic hash tag, AviD's solution makes sense.

    @AndreyBotalov "Usage of crypto" would most often be irrelevant of the algorithm. "When should I use symmetric encryption", it doesnt matter if you're using AES or DES; "How can I ensure my signature is valid for the correct public key" is irrelevant of RSA, DSA, or anything else; "How should we do key management" only matters if it is symmetric or asymmetric. And so on.

    Think of it this way: Crypto is a tool. In a professional's toolbox, there are many similar tools; if you want to ask specifics about the tools, there is a site for that. Just because we have many different heads for our drill, we dont need to tag eighth-inch-drillbit separately from three-and-half-inch-drillbit; or flathead-screwdriver from philipshead-screwdriver - using the tools would be the same either way.

    +1 on this. Hash is the best option.
