How to use the command 'rarcrack' (with examples)
This article will provide a step-by-step guide on how to use the ‘rarcrack’ command, which is a password cracker for rar, zip, and 7z archives. It will cover three main use cases: brute forcing the password for an archive, specifying the archive type, and using multiple threads.
Use case 1: Brute force the password for an archive (tries to guess the archive type)
Code:
rarcrack path/to/file.zip
Motivation: This use case is suitable when you have an encrypted archive and want to attempt to crack its password using a brute force approach. By default, the ‘rarcrack’ command will try to guess the archive type automatically.
Explanation: In this use case, you simply need to provide the path to the archive file you want to crack as an argument to the ‘rarcrack’ command.
Example output:
Checking path/to/file.zip
Tried all possible passwords. No password found.
In this example, the ‘rarcrack’ command will check the specified archive file and attempt to crack its password using a brute force method. If no password is found, it will display a message indicating that it tried all possible passwords.
Use case 2: Specify the archive type
Code:
rarcrack --type rar|zip|7z path/to/file.zip
Motivation: Sometimes, the ‘rarcrack’ command might not be able to guess the correct archive type automatically. In such cases, you can specify the archive type manually to ensure accurate password cracking.
Explanation: To specify the archive type, you need to use the ‘–type’ option followed by the appropriate archive type (rar, zip, or 7z). Additionally, you should provide the path to the archive file you want to crack as an argument.
Example output:
Checking path/to/file.zip
Tried all possible passwords. No password found.
In this example, the ‘rarcrack’ command will check the specified archive file with the manually specified archive type (zip) and attempt to crack its password using a brute force method. If no password is found, it will display a message indicating that it tried all possible passwords.
Use case 3: Use multiple threads
Code:
rarcrack --threads 6 path/to/file.zip
Motivation: This use case is helpful when you want to speed up the password cracking process by utilizing multiple threads. With multiple threads, the ‘rarcrack’ command can split the work and analyze different password combinations simultaneously.
Explanation: To use multiple threads, you need to use the ‘–threads’ option followed by the number of threads you want to utilize (in this case, 6). Additionally, provide the path to the archive file you want to crack as an argument.
Example output:
Checking path/to/file.zip
Tried all possible passwords. No password found.
In this example, the ‘rarcrack’ command will check the specified archive file and attempt to crack its password using a brute force method with six threads. If no password is found, it will display a message indicating that it tried all possible passwords.
Conclusion:
The ‘rarcrack’ command is a powerful tool for cracking passwords of rar, zip, and 7z archives. By using this command, you can try to recover forgotten or lost passwords, which can be helpful in situations where you need access to the contents of an encrypted archive. The use cases covered in this article include brute forcing the password, specifying the archive type, and utilizing multiple threads for faster password cracking.
