Hello Friends In this video I will talk about How to Crack Encrypted Hash Password - Using John The Ripper.

- I’ve encountered the following problems using John the Ripper. These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general. Sometimes I stumble across hashes on a pentest, but don’t recognise the format, don’t know if it’s supported by john, or whether there are multiple.
- For this to work you need to have built the community version of John the Ripper since it has extra utilities for ZIP and RAR files. For this exercise I have created password protected RAR and ZIP files, that each contain two files. Test.rar: RAR archive data, v1d, os: Unix test.zip: Zip archive data, at least v1.0 to extract The password for.
- John the Ripper cracked exactly 122.717.140 hashes, which is about 63.92% of the total file. I guess you could go higher than this rate if you use the rules in John the Ripper. If you want to try your own wordlist against my hashdump file, you can download it on this page.
- John.exe Cracking Passwords. John the Ripper’s primary modes to crack passwords are single crack mode, wordlist mode, and incremental. The single crack mode is the fastest and best mode if you have a full password file to crack. Wordlist mode compares the hash to a known list of potential password matches.
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.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.
John the Ripper is a favourite password cracking tool of many pentesters. There is plenty of documentation about its command line options.
I’ve encountered the following problems using John the Ripper. These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general.
- Sometimes I stumble across hashes on a pentest, but don’t recognise the format, don’t know if it’s supported by john, or whether there are multiple “–format” options I should try.
- The hashes you collect on a pentest sometimes need munging into a different format… but what’s the format john is expecting?
- John will occasionally recognise your hashes as the wrong type (e.g. “Raw MD5″ as “LM DES”). This is inevitable because some hashes look identical.
- Sometimes I gain access to a system, but can’t recall how to recover the password hashes for that particular application / OS.
These problems can all be sorted with a bit of googling or grepping through the john source code. I thought it might be helpful to compile a cheat sheet to reduce the amount of time I spend grepping and googling.
In the first release of this page I’ve:
- Copied example hashes out of the source code for most supported hash types.
- Provided examples of what your hashes.txt file might look like (though I’m sure other variations are supported that aren’t covered here yet).
- For each example hash I’ve stated whether it will be automatically recognised by john, or whether you’ll have to use the “–format” option (in which case I’ve included which –format option you need)
I haven’t yet done the following:
- Added reminders on how hashes can be collected.
- Added information on how to munge the hashes into a format supported by john.
