Abstract

At present, the traditional method of cracking WinRAR encryption is to use the CPU and GPU, but the potential password space is very large which requires a higher performance computing platform to find the correct password within a limited time. Therefore, this paper used the hardware platform of multi-FPGA to achieve a high-performance WinRAR crack algorithm. The SHA-1 algorithm was optimized by adding pre-calculation and using CSAC carry saved adder under the full-pipeline architecture, so as to improve the throughput of the algorithm. And it used the control state machine to optimize data splicing, to improve algorithm parallelism. At the same time, it used the asynchronous clock and multiple FIFO buffers to read and write the overall structure of the data optimization algorithm to reduce the coupling within the algorithm. The experimental results show that the final optimized resource utilization rate is 75% and the frequency reaches 200 MHz. The 4 Byte password deciphering speed is 102 796 per second, which is 100 times faster than CPU and 3.5 times faster than GPU.
