John The Ripper Nt Hash

John the Ripper is a favourite password cracking tool of many pentesters. Tamagotchi connection with four buttons instructions. There is plenty of documentation about its command line options.

Option) might be already cracked by previous invocations of John. (The message printed in that case has been changed to 'No password hashes left to crack (see FAQ)' starting with version 1.7.7.) To display cracked passwords, use 'john -show' on your password hash file(s). To force John to crack those same hashes again, remove the john.pot file. Root@kali:# john -show hash.txt 0 password hashes cracked, 1 left My question is, why does it say 0 password hashes cracked, when I've just cracked it moments ago? I want to view the previously cracked password. Using default input encoding: UTF-8 Loaded 1 password hash (Raw-SHA256 SHA256 128/128 SSE2 4x) Press 'q' or Ctrl-C to abort, almost any other key for status 0g 0:00:00:06 DONE (2017-01-06 12:47) 0g/s 2347Kp/s 2347Kc/s 2347KC/s Session completed show $ john -show mypassword 0 password hashes cracked, 1 left What did I do wrong? Nov 25, 2016 Yes I've just discovered what the the mangling rules are. Root@kali:/ctf# rm./root/.john/john.pot root@kali:/ctf# john shadow.bak Warning: detected hash type 'sha512crypt', but the string is also recognized as 'crypt' Use the '-format=crypt' option to force loading these as that type instead Using default input encoding: UTF-8 Loaded 4 password hashes with 4 different salts (sha512crypt.

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.

Guesses: 1 time: 0:00:00:02 100% (2) c/s: 3813 trying: temp1 The first line is generated as soon as the cracking begins. This line counts the. Number of passwords john is going to crack and some information about the type of. Encryption the passwords use. The next line is the cracked password with the username.

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.

This sheet was originally based on john-1.7.8-jumbo-5. Changes in supported hashes or hash formats since then may not be reflected on this page.
