(The well-used WPA and WPA2 running package software has been cracked. A weak password is attached to it, which can quickly break the wireless network password by using the computing performance of GPU. The computing speed can be increased by hundreds of times compared with using CPU. The working mode of this software is very simple. It uses a dictionary to decipher the WPA and WPA2 passwords on the wireless AP. It also supports 12 variable settings, such as letter case, number substitution, symbol sequence transformation, abbreviation, vowel substitution, which can be used on ATI and NVIDIA graphics cards.)
