FPGA Implementation of MD5 Algorithm for Password Storage

In this paper, the description of a hardware based MD5 core, which is designed and implemented using the hardware description language Verilog, is given. Hash functions are very common in the modern day world as a means of communication integrity and signature authentication. These functions produce a fixed-size fingerprint or hash value for a variable length (very long) message. MD5 represents one efficient algorithm for hashing the data, then, the purpose of implementation and used this algorithm is to give them some privacy in the application. The hash function MD5, Message digest Hash Algorithm, is examined in order to find the common constructs that can be used to implement it using hardware blocks of the FPGA.
