Password Disk Password Automatically Crack Research And Practice

This article mainly discusses a design process of the intelligent cipher solving system and study a problem which unlocks different locks' cipher in different case. It is mostly used for police domain.The system, which regarded the PIC16F877 microcontroller (8 bits) as a core, ensure its operating high efficiency and credibility. A high precision requirement is achieved by the stepping motors' sub divisional drive control and some problems such as step losing and "fly piece", which frequently occurred in use, are solved by adopting the curve of speed control. A feedback close-loop control is carried out by its sensor examine unit and at the same time a close man-computer communication system is built by using LCD, PS/2 mouse and keyboard. There are lots of custom experiences and advanced calculations are utilized in the software design and some unlocking cipher functions are realized.
