Comparison of original and modified blowfish algorithm is done by implementing both in Xilinx Virtex-5 XC5VLX50T FPGA using Verilog HDL and found that modified algorithm is efficient than the original in terms of encryption time by 16.9% and throughput by 18.7%. I need a progam in C++ that implements the blowfish algorithm and can be used to encrypt and decrypt a text file.
