gollark: Modern password hashing functions are designed to be slow to run (and to be fastest on general-purpose computing hardware and not ASICs) to mitigate this sort of thing.
gollark: If you do *not* use that, then people can store a bunch of precalculated mappings from hashes to original passwords (rainbow tables, yes) and work out the original.
gollark: That's why salts are recommended (they're a bit of extra data you store along with the password and feed to the hash function when hashing it in the first place and comparing passwords with the hash).
gollark: The main attack on this is that you can, sometimes even using dedicated ASICs/FPGAs, run hashes *very fast* on a lot of possibilities and figure out what the original password was.
gollark: Yep!
