Now, hashing and checksums aren't the same thing, but people seem to be using them fairly interchangeably, and they're certainly related in spirit. There are three solutions I can think of (and maybe other solutions that people will think of in the answers):
- Ensure that the tags have no overlap, going through all questions that use either and making sure the tag is appropriate;
- Make the tags into synonyms, and use them interchangeably from then on;
- Make one of the tags into a subset of the other (so all challenges about checksums or hashing will have one of the tags in particular, and a subset will have both).
Which of these options will lead to the best categorisations of these sorts of questions?
