Nice Article my friend Nikos but I have to stress some additional things. In my opinion it is faster than the official version of JtR with many additional features. In your first challenge you enter: ".
In Hashcat section I think both Challenge 1 and 2 are the same Anyway, good work and I hope to see more from you : :D. Hey, Thank you for commenting.
I'm glad you like my post. First of all, I used jumpo version of JTR because it's the most common version, and the most of us got it. So, that's why I didn't use magnum. As for --single mode, yes you are right: Concerning Hashcat,in challenge 1 and 2,I wanted to point out that the cracking speed is the same either in the "basic" way or in the -m method which you are specifying the encryption : Thanks!
Very nice info1 Question :. Check previous comments for more info. It has been said that any bettor needs to look at this, Watch this now or stop placing bets on sports Available Services. Wire Bank Transfer all over the world. Western Union Transfer all over the world. Spamming Tool. Social Media recovery. This was unbelievable and the happiest day of my life. The card have really change my life.John the Ripper is an old school hacker tool.
It has been around since the early days of Unix based systems and was always the go to tool for cracking passwords.
When thinking of current password breaking technology the you must think about GPU support. The default version of John the Ripper does not come with GPU support, however there are community builds known as the jumbo patch available that contain the additional code for GPU support as well as a larger number of supported hash types.
Generally John expects to receive password hashes in the form user:hash in a plain text file. When run against a file in this format John The Ripper does a pretty good job at identifying the hash type and beginning to try and break it. It is literally as simple as that, this uses the default password recovery mode as well as the default word list or dictionary.
In this command line help, we can see there are a large number of hash types that JTR is able to have a go at cracking. This help is from the Jumbo Patch version of John the Ripper hence the large number of available hash types. How to use John The Ripper to Recover Passwords Generally John expects to receive password hashes in the form user:hash in a plain text file.
Of course there are many more options available when running JTR, here is the command line help: John the Ripper password cracker, version 1.This post assumes you have access to a the target filesystem in question and want to extract and then crack the password hashes from the local machine. In this example I am going to crack the account passwords used in Metasploitable 2 but the techniques here can be used in many different scenarios.
However before we give the hashes to John, we need to combine the two files into one so that the user and the password hashes are merged. Now lets put john to work.
We could supply a password list for John to use but it comes with a default set of passwords so we may as well try those first. I let the crack run for another hour before cancelling but the root account had still not being cracked.
The password may be hidden in the John password list I would just need to let the cracking process run to completion to find out. One way or another, once complete, you can view each of the accounts and their corresponding passwords by running the following command and referencing the original file you gave John to crack:.

John the Ripper is included by default with Kali 2 — which is what I am using here. To start the crack, point John at our newly created file: john merged. Like this: Like LoadingThe list you can download here contains all the dictionnaries, and wordlists, I was able to find on the internet for the past two years. While I was using those lists to make my online database which you can find on this websiteI also made a bigger list, and tweaked it, to obtain a very unique and pertinent wordlist for password cracking.
This dictionnary not only contains the wordlists that you could find on the internet, I also made my own list, by analyzing first some passwords statistics thanks to Pipal to create a very useful list for you to download.
Because size matters, but not as much as we could think. There's no point having a very big list with big words from languages dictionnaries, because people are not likely to use those words as passwords.
So I analyzed what people used as passwords, such as surnames, with dates, where are the capital letters, and other stuff. I used those informations and I created a script to make what is for me a very pertinent wordlist.
The wordlist you can download on this page is, thanks to what I did, very unique, you won't find it somewhere else on the internet.
Of course I also have passwords that appears in other wordlists hopefully, I have the word "password" and "". You can try out this wordlist by using the online database on the website,though the online database is larger than the one you can download here, this one was created to be the best mix of storage space and efficiency, it contains exactly 1.

This wordlist has been sorted, of course, and all the double words were removed using the unix "sort uniq" command. If you decide to download this wordlist, please note that you can use it as-is, by feeding your favorite cracking tool.
I personnaly use John the Ripper with the argument --wordlist. If you have any question regarding the wordlist, or troubles with downloading, or anything else, you can contact me through the address : contact at md5decrypt.
John the Ripper benchmarks
As always, statistics are better than words. So I took some hours to find as many hashes as I could, by taking all the hashdumps I found such as eharmony, gamigo, ISW, insidepro, etc and several big lists of unfound MD5 hashes on great websites such as hashkiller. As a total, it gave me exactly I processed those hashes using my wordlist and John the Ripper 1.
John the Ripper cracked exactly 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.
This file wasn't created just to work with my wordlist, I really looked for all the hashes I could find just to try if my list was good. You can download the Md5decrypt's wordlist for free.
This wordlist is unique as I created it nearly from scratch, using only some base wordlist. I don't trust the best database are the one with every words in it. It takes a lot of time, disk space and isn't really efficient. The best way for me is to analyze the way people choose the passwords, then adapt the database to it. If you want to try the wordlist first, you can also download a sample of Md5decrypt's wordlist - 2. This is to fight against bots, your email address won't even be stored :.Initially, this page will be the place to collect and share trivial john —test benchmarks on different systems.
Please add your benchmark results to the tables below as appropriate. Please make sure to run the benchmarks on an otherwise idle system. For example, the Q CPU achieves an equivalent of just over 2.
Please note that for bit x86 targets those with xanyxmmxand xsse2 in their namesthe C compiler and its version are largely irrelevant, because almost all of the performance-critical code is written in assembly language anyway. However, other hash types may actually be affected by C compiler and its version, so multiple entries may be submitted.
With few exceptions, the operating system should not significantly affect JtR performance, however it affects what JtR versions and make targets you may use and what compilers and versions are available. Hence, it makes sense to list it and also to include benchmarks on the same hardware, but with different operating systems and thus with different make targets.
Luckily, there are not as many different operating systems as there are different gcc versions. Multiple benchmarks for different versions of the same operating system flavor, with everything else staying the same as well, should not be listed. If desired, for clarity, listings with obsolete operating system versions may be replaced with those for currently maintained ones.
That said, if in doubt whether your benchmark results are of value, please do submit themand please do not be offended if they are moved to another table or sub-page meant to hold likely insignificant results yet to be created, if the need arises.

So basically you're saying we can create impenetrable passwords by adding a line break at the end?
For increased security any control character should work. But you need U. Jasen I was bitten by this when moving from Win7 to Win10, they removed the ability to type a literal delete char into the password box at login.

They were still sending data until the server stopped. The data isn't confidential but important to us nonetheless. I tried running john the ripper on the hashes. It found 4 passwords out of I think it's too insecure so no server proposed it, at least not as default. Some servers e. I couldn't find a way to save an unsalted SHA hash, though.
Is it possible to create a htpasswd hash with SHA, without salt and only one round? The minimum seems to be a 8-byte salt and rounds with mkpasswd. I don't care much about security, I'd just like to set-up an FTP server which accepts incoming connections from the sensors. Broco suggested to use pyftpdlibwhich worked perfectly for my needs!
The script logs the passwords in plain text, which is acceptable because the data isn't confidential. After a few months, I'll switch to vsftpd. Sign up to join this community.

Question Is it possible to create a htpasswd hash with SHA, without salt and only one round? Is there another linux FTP server which can be configured to work with thoses hashes? Eric Duminil Eric Duminil 3 3 bronze badges. You might simply install a replacement FTP server, set up the accounts with the passwords you do know and use a network sniffer to collect the failing passwords of the accounts that you are missing. HBruijn: That could work, yes.
Thanks for the comment.
Do you know any "fake" FTP-server which simply dumps the failed passwords? EricDuminil Simply use a laptop with the same IP and wireshark.
