Now that we know what hashing and Hashcat are, let’s start cracking some passwords.īefore cracking a hash, let's create a couple of hashes to work with. You can find the Rockyou wordlist under /usr/share/wordlists in Kali Linux. It contains a list of commonly used passwords and is popular among pen testers. This can be a password wordlist, username wordlist, subdomain wordlist, and so on.Ī popular password wordlist is rockyou.txt. A word list is a list of commonly used terms. In addition to Hashcat, we will also need a wordlist. Once the installation is done, we can check Hashcat’s help menu using this command: $ hashcat -h Hashcat help menu Here is the command: $ brew install hashcatįor other operating systems, a full list of installation instructions can be found here. To install it on a Mac, you can use Homebrew. To install it in Ubuntu / Debian-based systems, use the following command: $ apt install hashcat Hashcat comes pre-installed in Kali and Parrot OS. Now that we know what Hashcat is, let's go and install it. ![]() Support for cracking multiple hashes in parallel.Support for more than 200 hashing algorithms.Other notable features of Hashcat include: Here is the difference between a CPU and a GPU if you want to learn more. GPUs are used in Gaming, Artificial intelligence, and can also be used to speed up password cracking. While CPUs are great for sequential tasks, GPUs have powerful parallel processing capabilities. Hashcat is also one of the few tools that can work with the GPU. It is a flexible and feature-rich tool that offers many ways of finding passwords from hashes. Hashcat is a fast password recovery tool that helps break complex password hashes. Now that we know how hashing works, let's look at what Hashcat is. A simple way to attack hashes is to have a list of common passwords hashed together. This approach is also what gives rise to hashing attacks. It is then compared with the original hash saved in the database. When we try to log in again, the same hashing algorithm is used to generate a hash for our input. When we signup for a website, they will hash our password before saving it (hopefully!). If hashes are not reversible, how would we compare the strings? Simple – we compare the hashes. We can apply encoding to mask/simplify strings while hashing is used to secure sensitive data like passwords. Hashing and encoding have different use cases. ![]() But if we hash a string, we can never get to the source string (maybe with quantum computers, but that's another topic for discussion). So what is the difference between hashing and encoding? When we encode a string, it can be easily decoded to get the source string. Here is how the same “Password123” will look if we encode it with base64: UGFzc3dvcmQxMjM= Now there is a similar algorithm called encoding. If we use the input string as “HelloWorld1234”, this will be the result: 850eaebd5c4bb931dbb2bbcf7994c021 For example, if we use the MD5 algorithm and hash two strings like “Password123” and “HelloWorld1234”, the final hash will have a fixed length. The length of a hash is always a constant, irrespective of the length of the input. To learn more about different hashing algorithms, you can read the article here. There are many hashing algorithms like MD5, SHA1, and so on. A hash function is a mathematical function that takes in the input string and generates another alphanumeric string. Hashing is the process of converting an alphanumeric string into a fixed-size string by using a hash function. Always get permission from the owner before scanning / brute-forcing / exploiting a system. ![]() If you use this information illegally and get into trouble, I am not responsible. Note: All my articles are for educational purposes. We will first start by looking at how hashing works in detail. Hashcat is a simple but powerful command line utility that helps us to – you guessed it – crack hashes. In this article, we will look at installing and working with Hashcat. This is why applications like Telegram use encryption while passwords are hashed. Encrypted data can be reversed using a key. A simple difference is that hashed data is not reversible. Hashing is often confused with encryption. From securing passwords to sensitive data, there are a variety of use cases for hashing. Hashing is one of the pillars of cybersecurity.
