Problems solved by technology

[0006] Ordinary brute force traversal algorithm can only substitute all possible keyboard characters for full arrangement and combination, even if the password is less than 8 digits, the traversal cannot be completed in a short time
Due to the fact that it cannot use the keyboard arrangement sequence, most of the passwords it traverses are invalid

Abstract

The present invention relates to the field of password encryption and decryption, in particular to a password traversal algorithm based on keyboard rules. Step 1: Obtain the characters on the keyboard and establish a password set according to the keyboard character rules. Step 2: Set the brute force traversal rules for the password set. 3: Use the brute force traversal rules and the password set as the data source of the traversal algorithm, and use the traversal algorithm to construct the characters in the password set to generate the final traversal password. According to the characteristics of keyboard rules, this solution designs a corresponding traversal algorithm, which can realize the traversal of passwords with different keyboard sequences, different starting positions, and different lengths.

Description

technical field [0001] The invention relates to the field of password encryption and decryption, in particular to a method for traversing passwords based on keyboard rules. Background technique [0002] Brute force traversal and dictionary traversal are the two most commonly used traversal methods in password recovery. Brute force traversal is to traverse all the passwords in the rules specified by the user, and dictionary traversal is to traverse the passwords in the dictionary file. The brute force method often requires more rules to cover as large a password space as possible to improve the success rate of password recovery, but too large a password space will double the traversal time, or even take hundreds of thousands of years, making password recovery meaningless. The success rate of the dictionary traversal method is often limited by the number of passwords in the dictionary. Since the number of passwords in the dictionary is generally not too many, the password tra...
