Problems solved by technology

Currently, file cracking is generally carried out using a PC, and the timeliness of cracking is poor, and cracking takes a lot of time

Moreover, there is no general-purpose hardware cracking platform on the market to crack different document file products.

[0003] According to the patent search of the existing technology, it is found that Patent No. 201110099441 "ultra-high throughput md5 brute force cracking device based on fpga" provides a design method for brute force cracking MD5 algorithm based on FPGA hardware. The defect of this patent lies in: brute force cracking consumes , the cracking performance is not as good as the rainbow table technology cracking

Moreover, the clock of the MD5 core computing module of the patent is only 50MHz, and the clock frequency is too low

[0004] Patent No. 200510025068 "File password cracking method" proposes a PC-based exhaustive cracking solution, which does not involve cracking the rainbow table, and the cracking of design defects is too time-consuming

[0005] Patent No. 201310326225 "Recovery Method and Device for Hash Value Password" proposes a cracking scheme based on PC-based rainbow table. The design defect of this patent is that the PC needs to generate a rainbow table, and then crack it after the generation of the rainbow table is completed. The duration increases the time to generate the rainbow table, which obviously takes too long

[0007] Efficient Implementation of Hash Algorithm on a Processor proposes a solution based on the ARM processor to implement the MD5 algorithm. The defect is that the speed and efficiency of the ARM processor are not as good as those of the FPGA, and the solution does not involve the cracking of the rainbow table. The cracking function is single and the hardware platform is limited. poor general performance
