We learned most of the basic information on John the Ripper in our Previous Article which can be found here. In this article, we will use John the Ripper to crack the password hashes of some of the file formats like zip, rar, pdf and much more.
To crack these password hashes, we are going to use some of the inbuilt and some other utilities which extract the password hash from the locked file. There are some utilities that come inbuilt with John which can be found using the following command.

John the Ripper can crack the PDF file passwords. You can encrypt your pdf online by using this website. This will compress and encrypt our pdf into a password protected file.pdf. So, when you will try to open the file, you will be greeted by the following prompt.
Hashcat is a popular password cracker and designed to break even the most complex passwords representation. To do this, it enables the cracking of a specific password in multiple ways, combined with versatility and speed.
Hashcat turns readable data into a garbled state (this is a random string of fixed-length size). Hashes do not allow someone to decrypt data with a specific key, as standard encryption protocols allow. Hashcat uses precomputed dictionaries, rainbow tables and even brute-force approaches to find an effective and efficient way to crack passwords.
The simplest way to crack a hash is to try first to guess the password. Each attempt is hashed and then is compared to the actual hashed value to see if they are the same, but the process can take a long time.

It is important to note that the simpler the password is, the easier it will be to detect.
Additionally, there are some GUI that makes hashcat easy to use. Hashview is one of the projects. This is a tool for security professionals to help organize and automate the repetitious tasks related to password cracking. In detail, it is a web application that manages Hashcat commands.
SummaryUsers must activate Windows 10 if they want to get all features. Apart from product key, Windows 10 activation can be cracked through various ways. In the essay, we will tell you how to crack Windows 10 activation for free.
(7) Risks in KMS Cracked ScriptTechnically speaking, the activation way has demerits. Your computer will become one members of the computer group and the developer of the KMS server is your administrator. This administrator has high authority so it can copy data in any member computer, even interrupt the computer performance. Therefore, it is suggested you build the KMS server by yourself, or choose a reliable KMS server when you want to crack Windows 10 via KMS scripts.3. Crack Windows Activation 10 via Third-Party Tool(1) How to Work via KMSpico Some activation tools, such as KMSTools, KMSpico and HEU KMS, collect KMS activation functions in the form of executable program, where Newbie can quickly finish the activation. We suggest you use KMSpico because it is developed by the KMS developers with more reliable functions. It can not only activate Windows systems but also Microsoft Office. Editions supported by KMSpico:Windows Vista Bussines / Enterprise
If you made substantial hardware changes to your PC, such as replacing your hard drive or motherboard, Windows might no longer be activated.Part 5. Disclaimer: Legal Risk in Windows Crack Globally, millions of people are using counterfeit Windows, especially those who live in developing countries with low economic level. It is noticed that using unofficial way to crack Windows activation is intellectual property infringement in all countries and regions.
Hi there again, aspiring hackers (and veterans as well)! I'm going to explain how to perform a dictionary attack on a WPA/WPA2 protected network with Wifite. Please note that this doesn't work with WPA Enterprise For that end, you'd have to use an Evil Twin to get the "Enterprise" auth attempt, and then crack it.
In a live Kali boot, you are logged on by default with the root user. If you let it running for a while (while cracking with the dictionary, pressumably) and it asks for a password to return to the session, it's 'toor' (root backwards).
When it succeeds deauthenticating a client (who has re-connect enabled by default), or a new client connects to the network, hopefully it will capture the handshake, and it'll start attempting to crack it with aircrack-ng and the dictionary file you gave it.
I used my country in lowercase letters as the passphrase (argentina), and as it's along the first words in this dictionary, it took only one second to crack it. For you it may take over an hour or two, depending on your processing power and if the passphrase is near the beginning or the end of the list.
Well, that's pretty much it. I hope you may find it helpful, but remember to look at OTW guides on Wireless cracking to know exactly what this script is doing, so you may tweak it furthermore or play with its options for more effectivity (type 'wifite --help' to see it's options).
One remarkable feature of John is that it can autodetect the encryption for common formats. This will save you a lot of time in researching the hash formats and finding the correct tool to crack them.
The final step would be to generate random passwords and use a password manager. There are a variety of options including the Chrome built-in Google password manager. If you use a strong password for each site you use, it becomes extremely hard to crack your password.
Now we can start using hashcat with the rockyou wordlist to crack the MD5 hashes. The rockyou wordlist comes pre-installed with Kali. If you are not using Kali you can use another wordlist, or download it from here.
In general, because a key of n bits can have 2npossible values, there can be at most 2n differentkeys. For example, a 16-bit key can have216 or 65,536 different values. If you had a computer thatcould try 100 of these keys every second, it would take 654 seconds orroughly 11 minutes to try all possible keys. (If you are cracking manykeys, the expected time to crack any given key is half that, as onaverage you will need to try half of the keys before you find theright one. Of course you could get lucky and try the key on your firstattempt, or you could be unlucky and have to try nearly every single key.)
Copy protection uses several "dirty" methods to detect if discs are "real" or not. Some of these methods work in Wine but many do not, such as the extremely invasive StarForce system. Wine would need to be altered to allow for almost rootkit-like functionality of programs to get some of these copy protection schemes to work, so support is likely to be a long time off if ever (some people use illegally modified or "cracked" games with the copy protection removed, but the Wine project cannot advocate that). 2ff7e9595c
