An Excel password cracking guide is here to quickly recover lost passwords.

Hello everyone, today I'm going to share some tips on cracking Excel passwords. Let's quickly recover those lost passwords together!

Excel is a commonly used tool in our daily work, and sometimes we encounter situations where we forget our passwords, which is really a headache. But don't worry, I'll teach you some practical methods to easily crack Excel passwords.

I. Understanding the Principles of Password Cracking

Actually, password cracking is not a mysterious thing. It mainly involves trying different password combinations through some technical means until you find the correct password. Of course, this requires some professional tools and techniques.

II. Commonly Used Excel Password Cracking Tools

1. Hashcat: This is a very powerful password cracking tool that supports multiple password hashing algorithms and can quickly crack various passwords. Moreover, it is very simple to use. You only need to enter the password hash value and some parameters to start cracking.
2. John the Ripper: This is also a very classic password cracking tool that supports a variety of password hashing algorithms, including MD5, SHA1, etc. Moreover, it can also crack passwords through dictionary attacks, brute force cracking, and other methods, which is very practical.

III. How to Crack Excel Passwords Using Hashcat

1. First, we need to obtain the password hash value of the Excel file. This can be obtained through specialized software, such as Office Password Recovery.
2. Then, we open the Hashcat software and select the corresponding password hashing algorithm, such as MD5.
3. Next, we need to import the dictionary file. A dictionary file is a file containing a large number of common passwords, and Hashcat uses the dictionary file to try different password combinations.
4. Finally, we click the "Start Cracking" button, and Hashcat will start trying different password combinations until it finds the correct password.

IV. How to Crack Excel Passwords Using John the Ripper

1. Similarly, we first need to obtain the password hash value of the Excel file.
2. Then, we open the John the Ripper software and select the corresponding password hashing algorithm, such as MD5.
3. Next, we need to create a password list file. This file can contain passwords we set ourselves, or it can be a list of common passwords downloaded from the internet.
4. Finally, we click the "Start Cracking" button, and John the Ripper will start trying different password combinations until he finds the right one.

V. Precautions

1. Cracking passwords is a very sensitive matter. We should abide by laws and regulations and not use them for illegal purposes.
2. Before cracking a password, we should try to obtain enough information, such as the length and complexity of the password, to improve the efficiency of cracking.
3. Cracking passwords requires a certain amount of time and computing resources. We should choose appropriate tools and methods based on our actual situation.
