Cryptography is best known as a method for keeping the substance of a message mystery. The designed Blowfish as a general-purpose algorithm intended as an alternative to the aging DES and free of the problems and constraints associated with other algorithms. The focus of proposed research is to implement built in self test using verilog coding on xilinx 14.7software. The main motivation behind for proposed algorithm is to extend the existing blowfish and improve performance. Previously it is designed for the 64 bit encryption and decryption process. Presently it is designed for the 128 bit processing. Calculate parameters using standard formula and approach and compare from existing work. Proposed 128 blowfish achieve better results than existing 64 blowfish.
