Hash is a one-way function and so does the DES encryption without the key for
decryption. In other words, once a message is passed through a hash function (or DES encryption),
it is very difficult to recover the message from the output of the hash function (or output of the DES
encryption without the key). Explain why a single DES encryption does not serve as a good hash
function.
