Description: The input of this hash function is a stream of binary data which is read from file. The data is encrypted by each 32bits. Each block first is initialized by doing XOR with the modified ciphertext and a random binary array, and then encrypted by passing 3 consecutive permutation boxes, and then expands to 48 bits, do XOR with the key. After this, do substitute box, the bits become 32bits again, now we get the first ciphertext. And we repeat doing these actions until the last block encrypted,
