In this paper, the application of the enhanced secure hash algorithm-512 is implemented on web applications specifically in password hashing. In addition to the enhancement of hash function, hill cipher is included for the salt generation to increase the complexity of generating hash tables that may be used as an attack on the algorithm. The testing of same passwords saved on the database is used to create hash collisions that will result to salt generation to produce a new hash message. The matrix encryption key provides five matrices to be selected upon based on the length of concatenated username, password, and concatenated characters from the username. In this process, same password will result to a different hash message that will to make it more secured from future attacks.
