Some zip files have passwords, but this is a headache for those who want to use the software in the zip file, but the passwords for these zip files can be cracked, as long as you know. Adding a decompression confirmation password to the compressed package is a valid way to protect the compressed package data, but if you forget the password, you are blocking yourself. Advanced ZIP Password Recovery (hereinafter referred to as AZPR) is currently the best Zip format compression package password cracking tool. The latest version is AZPR3.0, the release date is March 23, 2000, and the compressed package size is 670K. You can visit http://www.elcomsoft.com/azpr.html for the latest information on this software. As a powerful tool in this field, AZPR's outstanding features are: 1. The program provides a good operation interface, all the operation and operation setting items are directly in the program interface, you can directly select, and then you can quickly start the password crack operation, very convenient. 2. The exhaustive scans provided by the program are very fast, and according to the program's documentation, it can scan two million passwords per second on the Pentium II. 3. The program can scan and crack the compressed package with only one compressed file, and does not want other tools to ensure that there are multiple compressed files in the compressed package to complete the compression of the compressed package password. At the same time, the program also supports the compression package password cracking in the self-extended compression format of the EXE format, which is very comprehensive. 4. AZPR provides extremely powerful scan settings and control settings, such as custom scan password character length, character style (character set) included in the password, etc. These settings can effectively shorten the scan time, so that users can be shortened in a shorter time. Find the compressed package password accurately. If you generally remember the compressed package password style, it is very fast to scan the compressed package password using the relevant functions provided by the program. More importantly, for the registered version, the tool has no limit on the length of the compressed package password, which means you can scan encrypted passwords of any length. And the program provides four different scanning methods named Brute-force, Dictionary, Mask, and Plain-text to scan passwords for different formats. 5. The program scans the compressed package password without taking up a lot of CPU resources, so you can run the scan operation in the background of the system and do other things in the foreground. Moreover, AZPR provides the function of pausing and saving the current scan position. This function not only temporarily stops the scanning process, but also saves the currently completed scan and continues scanning when convenient. The specific usage of the tool is given below for your reference. First, the operating environment requirements of the program and the tools used to install AZPR in Windows 9x/NT/2000 environment. However, when I used the tool to crack the same compression package on Win 98 and Win 2000, I found that the crack speed on Win 2000 is obviously faster than that under Win 98, and even nearly twice as fast! For the machine environment, the program does not have special requirements, and the machine running Windows can run AZPR very well. However, the faster the speed of the PU, the shorter the time required to crack the password, the faster the 豢煞袢 氖 捎诮 捎诮 诹钇 诹钇 诹钇 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 越 越 越 越 越 越The download file of AZPR is a compressed file in Zip format. First, extend it to the specified path, run the Setup.exe program, and then click the “Next” button to complete the software installation. It is very convenient. After the software installation is complete, you can start it from the Advanced ZIP Password Recovery program group in the system start menu. The interface form after the program is started is shown in Figure 1. Second, crack the Zip compression package password If you need to use this tool to crack the password of the Zip compression package, you can follow the steps below: 1. To start the program, the first thing we see is the "Range" tag item. Click the “Load Zip-file into the project" button in the “Encrypt ZIP-file” item in the interface to select the Zip file to be cracked in the associated file list window. After confirming, return to the AZPR program interface. At this point, you can see that the file we selected is displayed in the text box in the item "Encrypt ZIP-file". 2. In the "Type of attack" option in the interface, select the password scanning method that the program can use. If you can't confirm the composition of the compressed package password characters, you should select "Brute-force" to scan within the maximum range. However, the scan time consumed is very long. If you can be sure that a word is being used as the password, select the “Dictionary” checkbox. If you generally remember one or more characters of the compressed package password, you can choose to use the "Mask" check box and set the password character form in the "Mask" text box in the interface, which can be extremely Zooming in on the scan range, you can also get the scan results in an extreme time. “Plain-text” is a special scanning method that uses a contrast method to scan encrypted passwords. And this scan has a number of restrictions, such as the need for an uncompressed file the same as the file in the compressed package, the same settings used to create the encrypted compressed package to compress the uncompressed file for comparison, etc., when you forget about the encrypted password Try this way when you are net. 3. If you choose to use the “Brute-force” or “Mask” scan settings, the checkboxes in the "Brute-force range options" option in the program interface are available, including the scan control settings. For example, scan all uppercase characters "All caps latin (A - Z)", scan all lowercase characters "All small latin (a - z)", scan numeric characters "All digits (0 - 9)" , scan all special characters <;All special symbols (!@…)”, space <;Space”, all format characters <;All printable", you can use the combination of the above checkboxes for password scanning, if you It can be confirmed that the password is a combination of these styles. In addition, you can set the characters that the program can start scanning in the “Start from” text box. If you remember the password is roughly four characters starting with “ld”; you can type ““paaa”” to indicate the first The characters are p, for other characters to start scanning from a, to the end of z. For scanning using Mask mode, you can enter the scanning format yourself. For example, the password of the compressed package is “zhangxp”, and you only remember that the password is seven characters, the first character is “z”, and the last one is “<quo;p” ;, at this time, you can enter “z in the "Mask” text box? ? ? p”. 4. If you use the "Brute-force" setting, switch to the "Length" tag item, the program will give the interface shown in Figure 2, which provides the length of the encrypted password that defines the compressed package. Minimal password length = [n] character(s)” in the interface means to set the minimum number of password characters, “Maximum password length = [n] character(s)” is the maximum number of encrypted password characters. When the two settings have the same value, you can confirm the number of scanned characters. Properly setting the number of scanned characters can greatly reduce the scan time. 5. If you use the "Dictionary" setting, switch to the "Dictionary" tag item, the program will give the interface shown in Figure 3. Regarding the "Dictionary" method of scanning, here is one more sentence: If you can determine that the encrypted password comes from a specific word in a text file, but you can't remember it, you can use this scanning method. The specific usage is to click the “Select dictionary file” button in the "Dictionary file path" option to select the document file to which the password belongs in the associated file list window and add it to the interface text box. “Start line #” in the interface means scanning from the specified line. 6. If you use the "Plain-text" method, you can switch to the "Plain-text" tag item, and the program will give the interface shown in Figure 4. In the "Plain-text file path" item, set the Zip file for scanning comparison. In addition, you can set the characters that may be used in the encrypted password in the Key item to limit the scan time. 7. At this point, the settings for using various scanning methods are completed, click "Start!" in the button bar of the program interface. ” button, the program starts scanning the encrypted password. After the scan is completed, if he finds the correct encrypted password, a dialog box as shown in Figure 5 will be given. As can be seen from the figure, the program gives the total number of passwords scanned except “Total passwords”, which is consumed by all scans. Time<quo;Total time”, the average number of passwords scanned per second Average speed (passwords per second)”, correct encrypted password“Password for this file”, hexadecimal encrypted password“ Password in HEX” and other related information, now you know what to do? The above is the method of using AZPR to crack the Zip compression package password. In addition to this function, the program also provides some auxiliary functions, including: 1. Encrypted compression package crack time test: In AZPR, this function is called Benchmark, which can roughly get the time required to crack the current encrypted compression package using the current cracking method. However, the estimated time provided by the program is longer than the actual time, and it is not very accurate. If you need to use this function, you can click the “Benchmark” button in the button bar of the program interface after setting the file to be cracked and the cracking method. 2. In the "Auto-save" option in the program interface, the auto save crack operation scan process file setting is provided. This function can be used to pause the scan and call the corresponding process file to continue scanning when recovery is required. The program automatically backs up the scanning process every 5 minutes by default. If you feel that the time is not suitable, you can set it in the “Save project every [x] minutes” option in the interface. 3. The running environment setting of the program is provided in the "Options" tag item in the program interface, and the interface form of the label item is as shown in FIG. 6. As you can see from the figure, the priority setting of the scan operation is provided in the “Priority options” option in the interface, including the background operation “Background” and the use of high priority “High”. In addition, in the interface, the setting program interface display mode, whether to create an operation log file, the interface language, the program version upgrade detection and the like are also provided, and the direct selection can be performed.
