Online Shopping System Based on Improved MD5

Message-Digest Algorithm 5, a hash function which is widely used in the field of computer security, can provide the message integrity protection. But to the field following certain rules, for example, by date of birth as a password, using the MD5 encryption algorithm, can still quickly decipher by MD5 decoding procedures of list form. In view of this situation, on the basis of MD5, putting forward a improved algorithm which has greatly security in data safety, and the improved algorithm is applied to the online shopping system based on ajax framework, for digital signature function of users on the system provides powerful safety security.
