WebMessage digests, also known as hash functions, are one-way functions; they accept a message of any size as input and produce as output a fixed-length message digest. MD5 is the third message-digest algorithm Rivest created. A good hash function should map the expected inputs as evenly as possible over its output range. That is, every hash value in the output range should be generated with roughly the same probability. The reason for this last requirement is that the cost of hashing-based methods goes up sharply as the number of collisions—pairs of inputs that are mapped to the same hash value—increases. If some hash values are more likely to occur than others, a larger fraction of t… kt law physics
