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 Thanks myrice
