What is hashcat?
Hashcat is a free and open-source password cracking tool. It can be used to recover passwords that have been hashed using a variety of algorithms, including MD5, SHA-1, and SHA-256. Hashcat is a powerful tool that can be used by both security professionals and attackers.
How does hashcat work?
Hashcat works by using a brute-force or dictionary attack to try to crack the password. A brute-force attack simply tries every possible combination of characters until the correct password is found. A dictionary attack uses a list of common passwords to try to crack the password.
How to use hashcat
Hashcat can be used on Windows, Linux, and macOS. To use hashcat, you will need to download the hashcat binary and install it on your computer. You will also need to download a wordlist, which is a list of common passwords. Once you have downloaded the hashcat binary and a wordlist, you can start cracking passwords.
Examples of using hashcat
Here are some examples of how to use hashcat to crack passwords:
- To crack a password that has been hashed using MD5, you would use the following command:
Code snippet
hashcat -m 0 -a 0 hash.txt wordlist.txt
- To crack a password that has been hashed using SHA-1, you would use the following command:
Code snippet
hashcat -m 5 -a 0 hash.txt wordlist.txt
- To crack a password that has been hashed using SHA-256, you would use the following command:
Code snippet
hashcat -m 10 -a 0 hash.txt wordlist.txt
Tips for using hashcat
Here are some tips for using hashcat to crack passwords:
- Use a powerful computer. Hashcat can be very CPU-intensive, so it is important to use a powerful computer if you want to crack passwords quickly.
- Use a large wordlist. The larger the wordlist, the more likely you are to crack the password.
- Use a GPU. Hashcat can be much faster if you use a GPU.
Conclusion
Hashcat is a powerful password cracking tool that can be used by both security professionals and attackers. It is important to use strong passwords to protect yourself from password cracking attacks.
