(standard crypt does 25 rounds). It then crypts the next 8 characters,
or an empty block if the password is less than 9 characters, using a
20-round version of crypt and the same salt as was used for the first
-block. Charaters after the first 16 are ignored. It always generates
+block. Characters after the first 16 are ignored. It always generates
a 16-byte hash, which is expressed together with the salt as a string
