Abstract: Fast MD5 collision algorithm falls to be used in real application of cracking MD5 password because it does not support reverse cracking. According to the issue, by analyzing the principle of MD5 password parallel cracking algorithm based on Graphic Processing Unit(GPU), this paper proposes a fast MD5 decryption algorithm based on GPU, and implements a fast MD5 password cracking system. Test result proves that the algorithm can accelerate the cracking of MD5 password.
