How to use Hashcat the powerful cracking tool?


Greeting Everyone! Hope All going well today in this blog we are about to learn how to use Hashcat with practical scenario Hashcat is one of the best and most powerful tools which is used for cracking hashes. Now we are going to learn how to use hashcat cracking tool in simple steps which will help you in your cryptography journey.

1.  Identify hash type – when we going to crack the hash we need to know the type of particular hash.

Unix style password hashes tools are very easy to recognize, as they have a prefix. The prefix tells you the hashing algorithm used to generate the hash. The standard format is  $format$rounds$salt$hash.

Example sha-512 – $6$pKyalkutOw0Tqq0u$4j18Lbicto3.

Windows passwords are hashed using NTLM, which is a variant of md4. They’re visually identical to md4 and md5 hashes, so it’s very important to use context to work out the hash type.

Prefix Algorithm
$1$ md5crypt, used in Cisco stuff and older Linux/Unix systems
$2$, $2a$, $2b$, $2x$, $2y$ Bcrypt (Popular for web applications)
$6$ sha512crypt (Default for most Linux/Unix systems)

Now we know how to identify hash but where we can identify the hash. For identify hash go to website –>





Now take the prefix from hash for example sha-512 hash prefix is $6$ go to website press Ctrl+f and put $6$ and take the hash-mode 1800 from first column.

2. Crack the hash –>  Put hash into the file I give the name of file hash.txt Hashcat powerful cracking tool use certain keywords like ( -a -m –force )

Tag Information
-a It use for give the attack-mode
-m It use for give the hash-mode of hash
–force Hashcat crecking tools will work without using of GPU. UPDATE: As of Kali 2020.2, hashcat 6.0 will run on the CPU without –force. I still recommend cracking on your host OS if you have a GPU, as it will be much much faster.

hashcat -a 0 -m 1800 hash.txt /usr/share/wordlists/rockyou.txt –force

Now hash is cracked  by powerful cracking hashcat powerful  tool and we got the password spaceman 





I attached for you some hash try to crack this.




Happy Hacking !!!
