Understanding Different Types of Password Hashes
Passwords are an essential part of our digital lives. We use them to protect our personal information, secure our online accounts, and ensure the privacy of our data. However, not all passwords are created equal. Some are stronger than others, and some are easier to crack. In this article, we will explore the different types of password hashes and how they can be cracked using a powerful tool called hashcat.
Before we dive into the world of password hashes, let’s first understand what a hash is. In simple terms, a hash is a mathematical function that takes an input (in this case, a password) and produces a fixed-size string of characters. This string is unique to the input, meaning that even a small change in the input will result in a completely different hash. Hash functions are designed to be fast and efficient, making them ideal for password storage.
Now that we have a basic understanding of hashes, let’s explore the different types of password hashes commonly used today. The most common type is the MD5 hash. MD5 is a widely used cryptographic hash function that produces a 128-bit hash value. However, MD5 is considered to be weak and easily crackable due to its vulnerabilities to collision attacks.
Another commonly used hash function is SHA-1. SHA-1, which stands for Secure Hash Algorithm 1, produces a 160-bit hash value. Like MD5, SHA-1 is also considered to be weak and vulnerable to collision attacks. In fact, both MD5 and SHA-1 have been deprecated by many organizations due to their security flaws.
To address the weaknesses of MD5 and SHA-1, more secure hash functions have been developed. One such function is bcrypt. Bcrypt is a password hashing function that is designed to be slow and computationally expensive. This makes it resistant to brute-force and dictionary attacks, as it takes a significant amount of time and computational power to calculate the hash.
Another secure hash function is Argon2. Argon2 is the winner of the Password Hashing Competition, a global competition to identify the best password hashing algorithm. Argon2 is designed to be memory-hard, meaning that it requires a large amount of memory to compute the hash. This makes it resistant to both brute-force and parallelization attacks.
Now that we have a good understanding of the different types of password hashes, let’s explore how they can be cracked using hashcat. Hashcat is a powerful password cracking tool that supports a wide range of hash types, including MD5, SHA-1, bcrypt, and Argon2.
Hashcat works by using the computational power of a computer’s GPU (Graphics Processing Unit) to calculate the hash of a given input and compare it to a target hash. It does this by trying different combinations of characters until it finds a match. This process, known as brute-forcing, can be time-consuming and resource-intensive, especially for strong and secure hashes like bcrypt and Argon2.
In conclusion, understanding the different types of password hashes is crucial for ensuring the security of our online accounts and personal information. While weak hashes like MD5 and SHA-1 are easily crackable, more secure hashes like bcrypt and Argon2 provide better protection against brute-force and dictionary attacks. Tools like hashcat can be used to crack password hashes, but it’s important to remember that cracking passwords is illegal unless you have explicit permission to do so.

Now that Hashcat is installed and your GPU is detected, let’s move on to configuring it. Hashcat uses what’s called a “rule-based attack” to crack password hashes. These rules define how Hashcat will manipulate the passwords it tries during the cracking process. You can find a variety of pre-defined rulesets online, or you can create your own custom rules.
To configure Hashcat with a ruleset, create a new text file and add your desired rules. Each rule should be on a separate line. Save the file with a “.rule” extension. Now, when you run Hashcat, you can specify the ruleset using the “-r” flag followed by the path to your rules file.
Before we start cracking password hashes, we need a hash to work with. You can obtain a hash by either extracting it from a system’s database or by using a tool like Hashcat’s “hash-identifier” to identify the hash type and then generate a hash for testing purposes.
Once you have a hash, you can start the cracking process. Run the command “hashcat -m [hash type] [hash file] [wordlist]” in your terminal or command prompt. Replace “[hash type]” with the appropriate hash type identifier, “[hash file]” with the path to your hash file, and “[wordlist]” with the path to a wordlist containing potential passwords.
Hashcat will now start trying different combinations of passwords from the wordlist, applying the rules you specified. Depending on the complexity of the password and the power of your GPU, this process can take anywhere from a few minutes to several hours.
And there you have it! A step-by-step guide to installing and configuring Hashcat for cracking password hashes. Remember, it’s important to use this tool responsibly and only on systems you have permission to test. Happy cracking!
