That OP is all over the place. For example, it's claiming hashes are vulnerable to "dictionary attacks" but then explains an enumeration attack instead (totally different thing, the former implying rainbow table approaches instead, which is not even relevant here at all), and then simultaneously complains about key semantic closeness, even though it has precisely nothing to do with anything (and would improve enumeration attack risks).

Not to mention that most of the details in the OP are simply wrong in general.

Explain yourself, OP
