John the Ripper. Next we’ll need the cracking tool itself. If you’re using Kali Linux, this tool is already installed. Download John the Ripper here. In my case I’m going to download the free version John the Ripper 1.8.0 (sources, tar.gz, 5.2 MB). Once downloaded, extract it with the following linux command. Aug 20, 2017 John The Ripper running in Termux (part 1 - crack hash SHA512). John The Ripper Tool in. Java Tutorial - Hash functions (MD2, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512. In this mode John the ripper uses a wordlist that can also be called a Dictionary and it compares the hashes of the words present in the Dictionary with the password hash. Example In this case we have a custom wordlist, and a hash that we need to compare.
Each time I teach my Security class, I give a month-long lab to crack as many passwords as possible. For this fall’s contest (opened on October 7, 2018), I used three different hash types: NTLM, MD5, and SHA-512. The password hashes (16 total):
65 total submissions. The answers:
- (MD5) yogibear:L1verpool! => 11 students cracked this
- (MD5) bigbear:unbelievable => 60 students cracked this
- (MD5) grizzlybear:zxcasdqwe123 => 56 students cracked this
- (MD5) pandabear:vulmjz => 7 students cracked this
- (MD5) yolandabear:kx7yy4 => 5 students cracked this
- (MD5) fancybear:sx708n => 7 students cracked this
- (MD5) jojobear:wmOhL3u4J => 0 students cracked this
- (SHA512) smokeybear:asdf => 60 students cracked this
- (SHA512) cocobear:meatball => 60 students cracked this
- (SHA512) yetibear:06mulesystems => 8 students cracked this
- (SHA512) blackbear:mzpixl => 3 students cracked this
- (SHA512) fozziebear:320299 => 18 students cracked this
- (SHA512) pedrobear:R6iLFUgG => 0 students cracked this
- (NTLM) cozybear:doofus => 62 students cracked this
- (NTLM) chicagobear:ihateyou => 62 students cracked this
- (NTLM) teddybear:w7zbyt => 45 students cracked this
To earn all 10 points for the lab, students had to crack 6 passwords. The final distribution:
The winners (tied) cracked 14 of the 16 passwords.

Student 2’s methodology:
To crack the majority of the passwords I’ve completed so far, I used John the Ripper and Hashcat. I began by using a series of wordlists on both the MD5 and SHA512 passwords, which I divided into two separate files consisting of only passwords hashed with the respective algorithms. To this point, I’ve used a scattering of the wordlists from the
Seclists/Leaked-Databases
folder, and have had the most success with rockyou.txt
. Using rockyou.txt
, I cracked two of the MD5 hashes and three of the SHA512 hashes.John The Ripper Crack Sha512 Encryption Version
I then applied a series of different rules to some of these wordlists, for both MD5 and SHA512 hashed passwords. For the SHA512 passwords, I have been using my computer at home (with a decent graphics card) to speed up the process. Using these rules, and Hashcat which I’ve found to be a better option for GPU cracking, I cracked another of the MD5 hashed passwords.
After using a number of wordlists with a collection of different rules, I turned to brute force incremental cracking, as well as Hashcat’s mask attack. Using these two brute force methods, I’ve cracked another three MD5 hashes, and one SHA512 hash.
For the NTLM passwords, I ran JtR (John the Ripper) with the default settings to crack two of the hashes. I considered using wordlists with rules to crack the remaining NTLM password, but ended up using a site (hashkiller.co.uk/ntlm-decrypter.aspx) with a huge number of computed NTLM hashes (since I noticed that these hashes weren’t salted) to crack this one.
