It is difficult to get the original information from a MD5 hash since MD5 is a one-way hash algorithm. MD5 decryption is based on MD5 calculation for brute force attack, which requires great computing resources. This paper presents an approach for MD5 calculation and decryption on GPU, which has high concurrency. The CUDA program performed on a PC with NVIDIA GTX 560TI graphics card. The experimental result has shown that the calculating speed is 150 million words per second, increasing from 10 to 20 times compared to program run on CPU (Core i7-950 @3.07GHz). GPU has great potential in future general-purpose computing and concurrent computing.
Keywords:MD5; GPU; CUDA; multithreading; parallel computing
