A complete guide to cracking Excel passwords, easily solving the problem of forgotten passwords.

In today's digital age, we often encounter situations where we need to open encrypted files, and forgetting the password is one of the most troublesome problems. Don't worry, today I'll share some complete guides on how to crack Excel passwords, helping you easily solve the problem of forgetting your password.

I. Understanding the Basic Principles of Excel Passwords

Excel passwords are mainly divided into two types: open passwords and change passwords. The open password is used to restrict others from opening the file, while the change password is used to restrict others from modifying the contents of the file. Before cracking Excel passwords, we need to understand the basic principles of these passwords in order to better crack them.

II. Common Excel Password Cracking Methods

1. Brute-force cracking method
   • Brute force cracking is one of the most basic password cracking methods. It cracks a password by trying all possible password combinations. Although this method is simple, it requires a lot of time and computational resources, so it is not very suitable for cracking complex passwords.
   • To improve the efficiency of brute-force cracking, we can use some password cracking tools, such as John the Ripper and Hashcat. These tools take advantage of your computer's multi-core processor and GPU acceleration to quickly try all possible password combinations.
2. Dictionary cracking method
   • Dictionary cracking is a dictionary-based password cracking method that attempts to crack passwords by using pre-prepared dictionary files. Dictionary files contain a large number of common password combinations, such as birthday, phone number, username, etc.
   • When using dictionary cracking, it is important to choose the appropriate dictionary file to increase the success rate of cracking. At the same time, we can also customize the dictionary file according to the specific situation and add some possible password combinations.
3. Sniffing cracking method
   • Sniffing cracking is a method of obtaining passwords by listening to network traffic. It is suitable for cracking Excel file passwords in a network environment. When a user opens an Excel file on the network, the password is transmitted in plaintext, which sniffers can capture and crack.
   • To prevent sniffing, we can use encryption protocols, such as SSL/TLS, to encrypt network traffic. At the same time, we can also change our passwords regularly to increase their security.

III. Using the Document Password Recovery Master Platform to Crack Excel Passwords
