An implementation and its evaluation of password cracking tool parallelized on GPGPU

General-purpose computing on graphics processing units (GPGPU) is popular computing technology to utilize in various fields. In the paper, we parallelize cryptographical hash processing of a password cracking tool, John the Ripper, by utilizing CUDA on GPGPU. We also evaluate our work to compare the processing time of hash processing parallelized by GPU with that of the John the Ripper on a dual-core CPU. Processing time of our implementation is 0.03% of that of the original one.
