Abstract—The research aims to develop an enhanced MD5 algorithm for the secure web development. The existing MD5 algorithm has many weaknesses that makes it vulnerable to different attacks such as brute force, rainbow table, birthday, dictionary etc. Despite these, the MD5 algorithm is still used in different applications, security protocols and even in the transmission and storage of digital data for verification, integrity and security of data by using checksum. The research focuses on mitigating the weaknesses inherent in the existing MD5 algorithm to secure web application and maintain data integrity and security. The research documents the proposal and implementation of an enhanced MD5 algorithm by varying its length and using a key to hash the data into its cipher form.

Index Terms—Cryptographic functions, MD5, hash function, rainbow table, brute force, dictionary attack.
