John The Ripper Crack Sha1 Hashes
The correct way is to extract the password hash from the file and then cracking it using John The Ripper. For this purpose, you need to get a ‘ jumbo’ build of John The Ripper, that supports Office files cracking. Note that John can't crack hashes of different types at the same time. If you happen to get a password file that uses more than one hash type, then you have to invoke John once for each hash type and you need to use this option to make John crack hashes of types other than the one it would autodetect by default. Hashes.com is a hash lookup service. This allows you to input an MD5, SHA-1, Vbulletin, Invision Power Board, MyBB, Bcrypt, Wordpress, SHA-256, SHA-512, MYSQL5 etc hash and search for its corresponding plaintext ('found') in our database of already-cracked hashes. It's like having your own massive hash-cracking cluster - but with immediate results! 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.

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.
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.

John is able to crack WPA-PSK and WPA2-PSK passwords. Recent changes have improved performance when there are multiple hashes in the input file, that have the same SSID (the routers 'name' string).
The input format is a printable hash, which can either be directly created with john's tool “wpapcap2john” (ships with jumbo) from a packet capture in pcap format as produced by tcpdump, wireshark or airodump-ng; or by doing an intermediate conversion to Hashcat's hccap format as described below.
You can convert airodump's .cap file to .hccap in one of the following ways:
When you have hccap file you need to convert it to john's input format using “hccap2john” program shipped with recent jumbo versions.It encodes hccap file to “$WPAPSK$essid#b64encoded hccap”
Example testcase you can get from http://wiki.wireshark.org/SampleCaptures?action=AttachFile&do=view&target=wpa-Induction.pcap or wpa-Induction.tar.gz
From that point you can use john as you always do. The format comes in two flavours:
- -format=wpapsk (will use CPUs, is SIMD and OpenMP capable)
- -format=wpapsk-opencl (for any OpenCL GPU or CPUs)
Example usage:
- $ ./john -w=password.lst -form=wpapsk-opencl crackme
How To Crack Password Hashes
If “Induction” is in your (by default it is not) password.lst file, john will crack it.
