MD5 algorithm. Plaintext data hashed by the MD5 algorithm, can form dense text/data summary of the application of this algorithm can achieve the e-mail encryption. Experimental steps: 1, fill the message: 10 ... 0, so that the message length is equal to 448mod512 2, add the plaintext length (64) 3, 4 words initialization register 4, the message from the 512-bits of data blocks (Y0, Y1, ...) for 4 rounds of 16 iterations per round
