2025-02-17 21:27:43

In daily work and life, we often encounter such troubles: forgetting the password of Excel files. This is like a lock that locks our precious data inside, which is very headache - inducing. However, today I will share with you some practical skills for Excel password cracking and also introduce a super excellent platform - Document Password Recovery Master Platform (https://www.mima8.cn).

I. Common Situations of Excel Password Recovery

First of all, we need to know that there are two main types of Excel passwords. One is the password required when opening a file. This password is like the gatekeeper of the file, preventing people without the password from entering to view the content. The other is the password required when modifying the file content. This is like putting a layer of protection on the file content to prevent others from modifying it at will.

When we forget the password to open a file, it may be because the time of setting the password is too long ago, or because we have set too many different passwords, resulting in confusion. And forgetting the password for modification is also not uncommon. Maybe we just set a temporary protection for the file at that time and later forgot the existence of this password.

II. Basic Methods of Excel Password Recovery

1. Brute Force Method This is a relatively direct method, but it also takes a long time. Simply put, it is to try all possible character combinations to find the correct password. However, the disadvantage of this method is obvious. That is, if the password is relatively complex, it may take a lot of time and may not be able to find the correct password at all. Moreover, this method requires the help of special software tools. For example, some password recovery software will start trying from simple character combinations, such as pure digital combinations (starting from 0000 and gradually increasing), and then try combinations of letters and numbers. However, when facing longer and more complex passwords, the efficiency of this method will become very low.

2. Dictionary Attack Method This method is relatively smarter than the brute force method. It is based on a pre - prepared "dictionary" that contains many common words, phrases and character combinations. The software will try passwords according to the contents of this dictionary. For example, many people will use their birthdays, names or some simple common words as passwords. Then the dictionary attack method is very likely to find these passwords. However, if the password is a very special and uncommon combination, this method may fail.

III. Advantages of Document Password Recovery Master Platform

1. Support Hash Decryption without Uploading Files This is really very important. Many people are worried that uploading files will lead to data leakage. After all, there may be our privacy information or important work data in the files. And the Document Password Recovery Master Platform uses hash decryption method, which can perform password recovery without uploading files. This is like performing decryption operations in a safe and closed space. There will be no risk of data leakage.

2. Low Price When looking for password recovery solutions, price is also a factor that everyone is very concerned about. Some password recovery services are too expensive, which makes people hesitate. But the price of the Document Password Recovery Master Platform is very low, which makes more people able to enjoy professional password recovery services. Whether it is personal users or small enterprise users, they do not need to spend too much money to solve the trouble of forgetting passwords.

3. No Need for Manual Operation The automation level of this platform is very high and there is no need for us to perform complex manual operations. We only need to follow the prompts of the platform and enter some necessary information, such as the hash value of the file, etc., and then we can wait for the platform to automatically perform password recovery. This is very convenient for those users who are not familiar with technical operations.

IV. How to Perform Excel Password Recovery on the Document Password Recovery Master Platform

1. Get the File Hash Value First of all, we need to get the hash value of the Excel file. There are different ways to obtain it in different operating systems. In the Windows system, we can use some special tools to obtain it. For example, we can use the CertUtil command. In the command prompt, enter CertUtil -hashfile [file path] [hash algorithm]. Here, the file path is the complete path of the Excel file we want to recover the password, and the hash algorithm can choose common MD5 or SHA - 1, etc. In this way, we can get the hash value of the file.

2. Enter Relevant Information on the Platform After getting the hash value, we can open the Document Password Recovery Master Platform (https://www.mima8.cn). Find the corresponding Excel password recovery entry on the platform and enter the hash value we just obtained. At the same time, we may also need to select some other information about the file, such as the version of the file. These information can help the platform perform password recovery more accurately.

3. Wait for the Password Recovery Result After entering the relevant information, we only need to wait patiently for the password recovery result of the platform. Because the platform uses efficient algorithms and technologies, it usually does not need to wait too long to get the result. When the password is recovered successfully, the platform will display the password to us, so that we can open or modify our Excel files smoothly.

V. Word File Password Recovery

The situation of forgetting the password of Word files is similar to that of Excel files. There are also opening file passwords and modifying file passwords.

1. For the situation of forgetting the opening password of Word files
2. The brute force and dictionary attack methods are also applicable to Word files to a certain extent. However, because the encryption mechanism of Word files may be different from that of Excel files, when using these methods, it may need to be adjusted according to the specific situation.

3. The Document Password Recovery Master Platform is also applicable to Word file password recovery. We can follow the method of obtaining the file hash value introduced above (if required by the platform) and then perform the corresponding operations on the platform.

4. For the situation of forgetting the modifying password of Word files

5. If the modifying password is forgotten, we can try some special tools. Some tools are specifically designed for Word file modifying password recovery. They may try to find the loopholes of modifying passwords by analyzing the structure and encryption method of the files.
6. Of course, the Document Password Recovery Master Platform may also have specific functions for Word file modifying password recovery. We can pay attention to the updates and help documents of the platform to make better use of the platform for password recovery.

VI. PDF File Password Recovery

PDF files are also often encrypted in our work and life.

1. Types and Characteristics of PDF File Passwords
2. PDF file passwords mainly include user passwords and owner passwords. User passwords are used to limit the opening of files. Only by entering the correct password can the file content be viewed. Owner passwords are more used to limit some operations of files, such as printing and copying.

3. The encryption strength of PDF files varies depending on the encryption algorithm and settings. Some PDF files may use relatively simple encryption algorithms, while others may use advanced encryption standards (AES) and other high - strength encryption algorithms.

4. PDF File Password Recovery Methods

5. For PDF files using simple encryption algorithms, we can try to use some online PDF password recovery tools. These tools usually analyze the encryption situation of PDF files first and then try some common password combinations. However, this method may not be effective for PDF files using high - strength encryption algorithms.
6. The Document Password Recovery Master Platform also has good support for PDF file password recovery. We can provide the necessary file information according to the requirements of the platform, such as the hash value of the file (if required), and then the platform will use its advanced algorithms to perform password recovery. Whether it is a user password or an owner password, the platform has a high probability of being able to recover.

VII. PPT File Password Recovery

PPT files are a common file format when we make presentation materials. Sometimes we also encounter the situation of forgetting passwords.

1. The Role and Common Problems of PPT File Passwords
2. PPT file passwords can also be divided into opening passwords and modifying passwords. The opening password prevents others from viewing the content of PPT, and the modifying password prevents others from modifying the layout and content of PPT at will.

3. When we forget the PPT file password, it may affect our work progress. For example, we urgently need to modify the PPT content for demonstration, but because we forget the password, we cannot operate.

4. Ways to Recover PPT File Passwords

5. Similar to Excel and Word files, the brute force and dictionary attack methods can be tried for PPT file password recovery. However, the success rate of these methods depends on the complexity of the password.
6. The Document Password Recovery Master Platform provides a convenient solution for PPT file password recovery. We can recover the password through the platform without worrying about the risk of data leakage, and the operation is simple and fast.

VIII. RAR, ZIP, 7z File Password Recovery

1. The Importance and Common Reasons for Forgetting the Passwords of These Compressed Files
2. RAR, ZIP, 7z and other compressed files are very convenient when we transfer and store data. We often compress and encrypt important files to protect the security of the files. However, sometimes we will forget the passwords of these compressed files. This may be because we set the password a long time ago and did not use it, or because we did not make good records when setting the password.

3. The passwords of these compressed files protect the decompression and viewing permissions of the files. If we forget the password, we cannot use the content in the compressed file normally.

4. Methods of Compressed File Password Recovery

5. For RAR, ZIP, 7z and other compressed files, brute force and dictionary attack are also common password recovery methods. However, because the encryption algorithms of these compressed files are relatively complex, brute force may take a lot of time.
6. The Document Password Recovery Master Platform has unique advantages for the password recovery of these compressed files. It can quickly analyze the encryption situation of compressed files and use its powerful algorithms to perform password recovery. Moreover, because the platform supports hash decryption without uploading files, we do not need to worry about the leakage of file contents.

In our daily work and life, forgetting file passwords is a very common problem. But with these password recovery methods and excellent platforms like the Document Password Recovery Master Platform, we can easily solve this problem. I hope that when you encounter the situation of forgetting file passwords, don't be nervous. Try according to the methods I shared.
