Abstract

The invention relates to a password setting method and device, computer equipment and a storage medium. The method comprises the following steps: dividing and encrypting a new password according to apreset password dividing rule to obtain a plurality of first encrypted character groups, and comparing each first encrypted character group with each second encrypted character group obtained by dividing and encrypting an old password according to the password dividing rule, and if at least one first encrypted character group is the same as any second encrypted character group, determining that the new password is invalid. After the new password and the old password are respectively divided, the repeated check of the first encrypted character group and the second encrypted character group is carried out in a polling manner, so that the condition that partial characters and complete characters of the new password and the old password are repeated is avoided to the greatest extent, the password strength of the new password is enhanced, and cracking difficulty of the new password is improved; and the probability that the new password is violently cracked is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a password setting method, device, computer equipment and storage medium. Background technique [0002] With the improvement of computer system security requirements, in the basic input and output system (Basic Input & Output System, BIOS), by increasing the strength requirements of the password in the power-on POST phase, the probability of the password being cracked by violence can be effectively reduced, thereby ensuring a certain degree System security. [0003] At present, the password setting method of the computer system BIOS is often to meet the strength requirements of the password by increasing the complexity of the password, for example, by not limiting the character length of the password, increasing the character types allowed to appear in the password as much as possible, and distinguishing letters Improve the strength of passwords by changing upper and...
