@CodesInChaos I revised that tag since it was merely used by a handful of questions, of which none of them specifically handled the
SHA3 competition, but rather
the algorithms that were proposed during that competition. Tagging the few questions accordingly made more sense to me than keeping a tag that will not be used anymore in the future since the competition is over. It may well be that I missed adding an additional tag like
skein here or there, but that can be fixed easily.
