Correct. Here's another interesting thing. Sometimes two different
inputs will result in the same hash. This is called a collision. It is
very rare, though.
Collisions are possible because there are a finite number of unique
hashes and an infinite number of inputs. Though unless I'm mistaken,
crypt may not be susceptible to collisions because the input is
truncated to a finite 64 bits.
