ABSTRACT: The MD5 algorithm is an algorithm that is able to turn arbitrarily different lengths of messages
into a 128-bit digest. Each digest of corresponding to the message is unique, and it is difficult to calculate the
message itself by digest. It specifically elaborates the realization of the principle and the security of the MD5
algorithm. For the brute-force method and collision attack mean, impro
