How to Crack MD5 Hash Passwords with Hashcat
MD5 is a widely used hashing algorithm that produces a 128-bit hash value from any input. It is designed to be fast and easy to compute, but it also has some serious weaknesses that make it vulnerable to brute force attacks. In this article, we will learn how to use Hashcat, a powerful command line tool that can crack hashes of various types, including MD5.
What is Hashcat?
Hashcat is a simple but powerful command line utility that helps us to crack hashes by using different attack modes and techniques. It supports many hashing algorithms, such as MD5, SHA1, SHA256, SHA512, MySQL, NTLM, Wordpress, Bcrypt and more. It can also handle different types of hashes, such as salted hashes, hashes with prefixes or suffixes, etc. Hashcat can use various sources of input, such as wordlists, dictionaries, masks, rules, combinations and more. It can also leverage the power of GPUs to speed up the cracking process.
How to Install Hashcat?
Hashcat is available for Windows, Linux and MacOS. You can download the latest version from the official website: https://hashcat.net/hashcat/. You can also find the source code on GitHub: https://github.com/hashcat/hashcat. To install Hashcat on Windows, you just need to extract the downloaded archive and run the executable file. To install Hashcat on Linux or MacOS, you need to compile it from source. You can follow the instructions on the README file or this guide: https://www.freecodecamp.org/news/hacking-with-hashcat-a-practical-guide/.
How to Use Hashcat?
To crack a password using Hashcat, here is the general syntax:
$ hashcat -m value -a value hashfile wordlist
Letâs dissect the syntax. We have used two flags, -m and -a. The -m flag is used to specify the hash type and the -a flag is to specify the attack mode. You can find the list of hash types and attack modes here: https://hashcat.net/wiki/doku.php?id=hashcat. Letâs crack our md5 hash password using a dictionary attack. A dictionary attack is when we use a list of common or possible passwords and try them one by one until we find a match. We need to have a file with the md5 hash we want to crack and a file with a wordlist of passwords. For example, letâs say we have a file called hash.txt with this content:
This is the md5 hash for âPassword123â. Letâs also say we have a file called wordlist.txt with some common passwords:
To crack the md5 hash using Hashcat and our wordlist, we can use this command:
$ hashcat -m 0 -a 0 hash.txt wordlist.txt
The -m 0 flag tells Hashcat that we are using md5 hashes and the -a 0 flag tells Hashcat that we are using a dictionary attack. After running the command, Hashcat will start cracking the hash and display the progress and results on the screen. If it finds a match, it will show us the plaintext password and the status âCrackedâ.
In this article, we learned how to crack md5 hash passwords using Hashcat. We saw how to install Hashcat on different platforms, how to use its basic syntax and options, and how to perform a dictionary attack on an md5 hash. Hashcat is a powerful tool that can help us to recover lost aa16f39245
