 @BevanR It doesn't need to. Here's why:
 Let's assume they're using Rainbow tables for a minute. Know how many
 combinations you'd need to store in a table for a 32 character password?
 `95^32, or 1.9 * 10^63 roughly 1.9 vagillion`. So first, you'd need to
 generate that table. Now, let's just assume I can make that table
 instantly, or I already have it (which irl is not the case at all). Now,
 GPU based rainbow table is the fastest method, and let's assume we can do
 1.720 billion comparisons per second (which is a really high number). So
 the time to compute is `95^32 / 1.720 billion * seconds or 1.126×10^54
 seconds or 3.569×10^46 years or roughly 2.6×10^36 * the estimated age of
 our universe`. Sure, rainbow-tables help, but not as much as you’d think.
