In daily computer operation, we can freely pass your password anytime, anywhere - boot to use the CMOS password, enter the Windows 98 to use the user password, edit the Word document to set the document password ... All of this is available for the user's data security The necessary security! However, with the increase in the scope of the cryptography, the case of the forgotten password is also increasing, and no one can guarantee that you will never forget the password)! How to crack these passwords after I forgot your password, and reduce the loss as much as possible, becoming a topic of the majority of users. In order to facilitate the user's use, it will now make a brief introduction to everyone using the crack method of computer passwords:
First, boot password
According to the user settings, the boot password is generally divided into two different situations. One is the setup password (when using this method, the system can start directly, but only when entering the BIOS setting); the other is SYSTEM Password (when using this method, both direct startup or BIOS settings require input password, no password will not be incomplete). For these two passwords set, our crack method is different:
1, setup password
If the computer can be guided normally, just cannot enter the BIOS setting (ie, set the setup password), then we only need to start Debug in the DOS state after the password, then enter the following command to handle the password:
_ o 70 16
_ o 71 16
_Q
In addition, users who are not familiar with Debug can also
Http://www.newhua.com/down/cmospwwd.zip Download a tool software CMOSPWD dealing with CMOS password. Then start the program at DOS, which will display the user's CMOS password (CMOSPWD supports Acer, AMI, Award, Compaq, Dell, IBM, Packard Bell, Phoenix, Zenith Ami, etc.), which is very convenient to use.
2, System Password
If there is no password, you can't start the computer at all (that is, set the SYSTEM password), then we can't solve the problem for forgotten password through the software. At this time, the only way is to open the chassis, discharge the CMOS, clear all the contents in the CMOS (of course, including the password), and then reboot. In addition, some motherboards have set the CMOS password to clear the jumper, and the jumper can also be shorter to achieve the same purpose (see the motherboard manual).
Second, Windows password
1, Windows boot password
Forgetting the startup password of Windows 98 does not affect the system's startup, it will cause users to enter their own personal settings, so crack the Windows 98's startup password to find "loss" "personality" is also necessary. To do this, we can delete all personal information files in the * .pwl password file and the pROFILES subdirectories in the Windows installation directory, then restart Windows 98, the system will pop up a password setting box that does not contain any username, we don't have Enter anything, click the "OK" button, the Windows 98 password is deleted. In addition, the UserProfiles under the registry database HKEY_LOCAL_MACHINE, NETWORK, and LOGON branches are modified to "0", and then restarting Windows 98 can also achieve the same purpose.
2, screen protection password
Using the screen protection feature of the system prevents others from stealing their own computers in their absence, thus playing the role of protecting data security. However, if there is no other restriction function, the system's screen protection password is very fragile. We only need to use the "reset" button after the forgotten password (some design imperfect screen saver can even use Ctrl Alt Del to force off, and the operation is simpler), then click on the white space and from the pop-up In the shortcut menu, execute the Properties command, open the Display Properties setting box and click the Screen Protection tab, and finally cancel the Password Protection option (no confirmation password when you cancel this option). In addition, it is said that there is still a disc that specializes in crack screen protection passwords on the market. After inserting the disc, it will use the automatic run function of Windows 98 to start the screen protected password crack program saved on the disc, analyze the password of the screen saver, decipher, and finally display the password on the screen or write to the floppy disk. It is more convenient (sorry, this feature is just the way, "I didn't see such an optical disc). 3, power management password
The power management function of the Windows 98 can also set a password. After setting this feature, the system will require input password when returning from the energy-saving state, thereby achieving the purpose of the protection system to a certain extent. However, since the password of the power management function is exactly the same as the startup password of Windows 98, we only need to crack the Windows 98 startup password according to the front method, and its power management password will not be broken.
As can be seen from the above introduction, the password protection function of Windows 98 is not perfect. Whether it is starting password or screen protection, the power management password is very fragile, we must supplemented by other control measures to prevent others from intrusion, For details, please refer to the relevant information.
Third, compressed file password
1, Winzip
When the user is forgotten the password of the ZIP compressed package
Http://www.golubev.com/ Download a Decryption Software for Cracked the ZIP Compressed Package Password UZPC (Ultra Zip Password Cracker), use it to help us find the lost password.
UZPC interface As shown in Figure 1, we only need to perform the "new" command of the "Task" menu, and select the ZIP file that you want to crack your password from the pop-up dialog box, then UZPC will open a "preferences" Dialog (as shown in Figure 2). Users should select which files in the ZIP compression package from the "Archive Files" list box (WinZip has different passwords for different files in the same zip compression package, but most ZIP compression packets are not used. This feature, which usually sets the same password for all the files, so common ZIP password cracking software can only handle the ZIP document of such the same password, which is often invalid for the ZIP compression package containing multiple passwords. UzPC is different, which can decrypt the passwords of different files in the ZIP compression package to better meet the requirements of the majority of users. The "Archive Files" list box is used to select the same ZIP compression package. Different password files).
Next, we should choose the appropriate decryption method (mainly "back door", "exhaustive way", "dictionary method" and "mode matching mode", we generally use "Brute Force"). After setting up, click the "Next" button, a "Brute Force Atck Parameter" dialog box (as shown in Figure 3) is popped, requiring the majority of the user to crack the password parameters (if you include case you write letters, whether to include numbers , Space, symbol or include all content, length, etc. of a password, etc.). Finally, click the "Go" button, the system uses the exhaustive method to test all possible password combinations until the final result is found, it is very convenient to use. It is also necessary to explain that if the number of bits of the password is long, the UZPC test can take a long time. To facilitate the user's use, UZPC deliberately provides a temporary interrupt operation and continuing to test from the interruption. We only need to record the current crack status during the test process, and then you can restarter The ongoing test does not have to worry about data loss. Thereafter, we only need to click the "Open" button in UzPC, open the last record, UZPC will continue to find from the interruption, saving the user's time.
2, ARJ
When the password for the ARJ compresses the package, we can go
Http://www.elcomsoft.com/ Download a professional ARJ compressed package password cracking software AAPR (Advanced Arj Password Recovery), use it to find the password of the ARJ compressed package. AAPR's interface As shown in Figure 4, we only need to select the ARJ compression package you want to crack from the "Arj Password-Encrypted File" dialog box, and select the scope of the password in the "Brute-Force Range Options" dialog (also Set whether or not to include cases, including numbers, spaces, symbols, or include all characters, etc.). Finally, click the "START" button, the system uses the exhaustive method to test all possible password combinations. After finding the password, it will be displayed, which is very convenient to use!
3, RAR
RAR is also a very popular compression software, users can go after the password of the RAR compression package
Http://www.ssl.stu.neva.ru/ Download a CRARK software to crack it. This is a command line utility that is mainly cracked by the command line to achieve the password of the RAR compression package. The format of its command is: "CRARK command line parameter RAR compression package file name". However, in fact, we generally use the "CRARK RAR Compressed Package File Name" command directly to use the default parameters to achieve the purpose of cracking the password of the RAR compression package.
Attachment: CRARK's meaning of command line parameters:
-l
-g
-S
-d
-u
-p
Fourth, text processing software password
1, WPS
1) WPS for DOS
The old version of WPS has a general password ctrl-qiubojun, we only need to use this password to open all encrypted documents, and then copy the contents of the document into other documents to solve the problem (using universal password to open The modification of the document cannot be stored).
2) WPS 2000
Everyone knows that WPS 2000 uses two different levels of document encryption, namely "common encryption" and "Top Secret Implicity". It is talked in the specification that when the user has forgotten the document password, if the document is "ordinary encryption" mode, you can save the technical staff of Jinshan, which helps you find forgotten password; if the document is used It is "Top Secret Encryption" mode, and the password will not decrypt it at all, but the fact is not the case. Whether it is forgotten the "normal" password or "Top Secret" password, we can download a software called EWPR (Edward WPS Password Recovery) to crack the software called EWPR (Edward WPS Password Recovery). This is a password cracking software edited by the Chinese (but I always don't understand why there are so many Chinese people like to edit the English interface), it provides "latter way", "exhaustive way", "Dictionary mode" And four kinds of decryption methods such as "mode matching mode" (for general users, the most useful value is still "exhaustive ways"), can decrypt the documentation using "normal encryption" and "Top Secret" (The operation is exactly the same).
Specifically, when we use EWPR to crack the password of the WPS 2000 document, we should first specify the desired WPS 2000 document (shown in Figure 5) in the "Encrypt WPS 2000 File" dialog box, and in "Type of Select the appropriate password crack mode in the attic list box (generally should select "Brute-force" exhaustion). Next, the password range that may be included in the "Brute-Force Range Options" list box should be selected according to the specific situation, and the character that starts to find in the "Start from" dialog box (mainly used to continue from the last interruption) Crack. After setting these options, we only need to click the "Run" button, EWPR will use the exhaustive method to crack the password of the WPS 2000 document, use it is very convenient (during operation, we can pass "pause" and "resume") The button is temporarily interrupting and continues to run from the interruption).
2, office
The password protection function of WPS 2000 is not safe, then what about Microsoft's Office? In fact, Microsoft's safety is more reliable (the security issues such as Windows 98, IE and other software is typical textbooks). The software that cracked the password of the Office series document, however, the most commonly used is AOPR (all called Advanced Office 97 Password Recovery, the download URL is
http://www.elcomsoft.com/). The software can simultaneously crack the password generated by Word, Excel, and Access in the Microsoft Office Series. This is eliminated by the user from the user, using each individual password cracking software. In addition, AOPR can search for the password of the word * .dot template file, which is not available in other similar software! It must be said that AOPR is developed for Office 97 (when the AOPR, Office 2000 has not yet been found), but the format of Office 2000 documents is basically no difference in the format of Office 97 document, so we can also use AOPR to Office The password of the 2000 document is cracked (at least I have found any problems during use).
After starting AOPR (as shown in Figure 6), we only need to select the Office document for the forgotten password from the "Encrypted Office 97 Document" dialog box, and select the range of the password in the "Brute -force Range Options" dialog, then Select the appropriate password crack mode in the "Type of Attack" list box (of course, "Brute-Force" is selected as the previous one), and finally click the "Start" button, the system will use the exhaustive method to all possible passwords. Combination is tested, then display it after finding the password (the method of use of different software seems to be almost). How, do you have a good effect? 3, Lotus Word Pro
Users who use lotus companies (IBM subsidiaries) may not have much, but the software's function is not inferior to Microsoft's Word (more advanced in some respects), in foreign countries The application range is very broad (many users often receive mails using Lotus Word Pro format), and most Chinese and foreign joint ventures are also using Lotus Word Pro to perform daily text processing, so this is one and the Lotus Word Pro is cracked. Methods to make a presentation. When the user forgets the Lotus Word Pro password, we can go
Http://www.lostpassword.com Download a WPROKEYD (Password Recovery for Lotus Word Pro) crack.
WProKeyd is a application specifically for cracking the Lotus Word Pro document code. We first click on the "Settings" button after starting the program (as shown in Figure 7), open the "Brute-Force Settings" dialog, for WProKeyd The crack state is set (mainly in the "Password Character Set" list box to select a password range). After the settings, we only need to drag the forgotten Lotus Word Pro document (* .LWP file) to the WProKeyd window, WPROKEYD will test all possible passwords according to the range of users specified by the user, until Find the password.
V. ICQ password
ICQ is currently the most popular network paging software. Many people are inseparable from this to the Internet. In the process of using ICQ, we must enter your own personal password. If you forget your password, you mean that all the paging numbers and conversations will be lost, which is absolutely unacceptable! Don't worry, ICQ password crack software ICQ Password Reveler can solve this problem (
http://www.encrsoft.com/). ICQ Password Reveler is a command line utility under a DOS. Users only need to execute the file under the NewDB subfolder of the ICQ installation folder, and then follow the screen prompt to enter your own UIN (shown in Figure 8), the system will Looking back to "long-lost" ICQ password, it is very convenient to use.
6. Use the password displayed by "***"
Everyone knows that Foxmail has the ability to remember the user's mailbox password, which can memorize the password of the user's mailbox, then collect mail directly, so that the cumbersome steps of the user manually enter the password. There is a problem, that is, the user can easily forget the mailbox password after the password for a long time, and the password recorded in the foxmail is displayed by "*", we can't see it directly (similar situation is very common), this should How to solve it? Don't worry, "Knight Software Password Viewer" can crack this password! "Knight Software Password Viewer" is a tool software specifically used to use "*" display password in the application dialog, which can detect the original characters of these passwords and display them in front of the user. With it, "*" is no longer a trench that cannot be over. The interface of the "Keros Software Password Viewer" is shown in Figure 9. We want to use it to crack a password, just open the password setting dialog box for other applications (ie, display "*" window), then use the mouse "The Knight Software" icon in the "Knight Software Password Viewer" is dragged to the "*" password of these applications, "The Knight Software Password Viewer" will crack these "*" password and display its original characters. In the Password box, thereby meeting the needs of users. The Download Uxt of the Knight Software Password Viewer is: http://xksoft.yeah.net/.
After reading the introduction above, I believe that you will never worry about your password, but in contrast, there may be a user who is safe to safely. In fact, we don't have to be so nervous. The cracking method used by these password cracking software is mainly exhausted. When the password is longer, all possible volumes are very large. At present, the computer's computing speed does not meet the poor longer password. Requirements, this means that as long as we set your password enough, others "peep" our secret opportunity is not much (of course, the password should be at least 8 or more, and should be a combination of numbers, letters and symbols). In addition, in order to prevent the "***" software, the "***" display password is used, and the user is best not to use the software's automatic memory password function, but directly enter the password directly when needed.
