1. Hashing is a one-way function that maps a message to a fixed-size sequence of bits (hashed value) with the assumption it is extremely difficult to reverse the process. Given the hashed-value, it is practically impossible to compute the original message given the hashed-value. It is extremely rare that two messages hash to the same value. When this happens, we refer to the event as a "collision". In this paper, you are going to discuss why are collisions bad to message integrity. Also discuss the chances of collisions with the algorithm Message Digest 5 (MD5).
