No. In xsha512-cuda format(But not others). I support password length
max to 125. I do the follows:
1. In a crack, (in a crypt_all() call), if length of all password <=
16, I only copy the password array with length = 16
2. Otherwise, if there is one or more password length > 16, I also
copy the extend password array
With 1, we have fast crack on short password. And with 2, this format
can also crack password length < 125
