Abstract

The invention discloses a statistics and analysis method and a statistics and analysis device for computer passwords. The method comprises the following steps: dividing the computer passwords in a password library into multiple groups according to the digits of the computer passwords; carrying out statistics and analysis on the password quantity corresponding to each regular expression in each group of computer passwords according to the preset regular expressions; sorting the regular expressions of each group of computer passwords according to the password quantity corresponding to each regular expression to obtain the statistics and analysis result of the computer passwords. According to the statistics and analysis method and the statistics and analysis device, the regular expressions sorted according to the statistical quantity of the computer passwords can be obtained by grouping the computer passwords and carrying out statistics and analysis on each group of passwords through the regular expressions, so that the hit rate of decrypting the computer passwords is improved; and analysis operation on a large-scale password library is supported.

Description

technical field [0001] The invention relates to the field of computers, in particular to a computer password statistical analysis method and device. Background technique [0002] Brute force cracking based on rules or dictionaries is a common method to implement computer password decryption internationally or in the industry. Relevant high-tech enterprises have developed a distributed decryption platform with powerful functions and flexible configuration with the help of acceleration devices such as Graphics Processing Unit (GPU). American Passware, Russian Elcomsoft, my country's Xiamen Meiya Pico Information Co., Ltd. and other companies have successfully developed and publicly sold password decryption software or equipment, and their main algorithm range and technical parameters have become recognized standards in the industry. [0003] PasswareKitForensic provides a complete electronic evidence decryption solution, which can implement dictionary or rule-based brute forc...
