What is Password Cracking?
You have a shell, alright go to the path before /publichtml 'xxxx/publichtml/' you gonna find a file there called '.contact' or 'contactemail' edit it and replace with your email and save it. May 31, 2017 And time ago we posted a post about how to get a free cpanel license for test purposes, now one of the things you may face when you are using cPanel is the need to verify cPanel license details. After testing your free 15 days trial version, you will have to buy a license for your VPS/Cloud or Dedicated server IP address in order to continue. Using the cPanel proxy domain examples you should be able to still access the particular service even behind a firewall that is blocking the standard ports. Hi Everyone, I need latest cPanel&WHM crack or bypass license. CPanel is a tool that puts all the accounts in one place, accessible with a couple of clicks. Change password, create email accounts etc. Easily access cPanel. Size: 8.0 MB, Price: USD $29.95, License: Shareware, Author: HighDesert Software Co.

Password cracking is the process of attempting to gain Unauthorized access to restricted systems using common passwords or algorithms that guess passwords. In other words, it’s an art of obtaining the correct password that gives access to a system protected by an authentication method.
Password cracking employs a number of techniques to achieve its goals. The cracking process can involve either comparing stored passwords against word list or use algorithms to generate passwords that match
In this Tutorial, we will introduce you to the common password cracking techniques and the countermeasures you can implement to protect systems against such attacks.
Topics covered in this tutorial
What is password strength?
Password strength is the measure of a password’s efficiency to resist password cracking attacks. The strength of a password is determined by;
- Length: the number of characters the password contains.
- Complexity: does it use a combination of letters, numbers, and symbol?
- Unpredictability: is it something that can be guessed easily by an attacker?
Let’s now look at a practical example. We will use three passwords namely
1. password
2. password1
3. #password1$
For this example, we will use the password strength indicator of Cpanel when creating passwords. The images below show the password strengths of each of the above-listed passwords.
Note: the password used is password the strength is 1, and it’s very weak.
Note: the password used is password1 the strength is 28, and it’s still weak.
Note: The password used is #password1$ the strength is 60 and it’s strong.
The higher the strength number, better the password.
Let’s suppose that we have to store our above passwords using md5 encryption. We will use an online md5 hash generator to convert our passwords into md5 hashes.
The table below shows the password hashes| Password | MD5 Hash | Cpanel Strength Indicator |
|---|---|---|
| password | 5f4dcc3b5aa765d61d8327deb882cf99 | 1 |
| password1 | 7c6a180b36896a0a8c02787eeafb0e4c | 28 |
| #password1$ | 29e08fb7103c327d68327f23d8d9256c | 60 |
We will now use http://www.md5this.com/ to crack the above hashes. The images below show the password cracking results for the above passwords.
As you can see from the above results, we managed to crack the first and second passwords that had lower strength numbers. We didn’t manage to crack the third password which was longer, complex and unpredictable. It had a higher strength number.

Password cracking techniques
There are a number of techniques that can be used to crack passwords. We will describe the most commonly used ones below;
- Dictionary attack– This method involves the use of a wordlist to compare against user passwords.
- Brute force attack– This method is similar to the dictionary attack. Brute force attacks use algorithms that combine alpha-numeric characters and symbols to come up with passwords for the attack. For example, a password of the value “password” can also be tried as p@$$word using the brute force attack.
- Rainbow table attack– This method uses pre-computed hashes. Let’s assume that we have a database which stores passwords as md5 hashes. We can create another database that has md5 hashes of commonly used passwords. We can then compare the password hash we have against the stored hashes in the database. If a match is found, then we have the password.
- Guess– As the name suggests, this method involves guessing. Passwords such as qwerty, password, admin, etc. are commonly used or set as default passwords. If they have not been changed or if the user is careless when selecting passwords, then they can be easily compromised.
- Spidering– Most organizations use passwords that contain company information. This information can be found on company websites, social media such as facebook, twitter, etc. Spidering gathers information from these sources to come up with word lists. The word list is then used to perform dictionary and brute force attacks.

Password cracking tool
These are software programs that are used to crack user passwords. We already looked at a similar tool in the above example on password strengths. The website www.md5this.com uses a rainbow table to crack passwords. We will now look at some of the commonly used tools
John the Ripper
John the Ripper uses the command prompt to crack passwords. This makes it suitable for advanced users who are comfortable working with commands. It uses to wordlist to crack passwords. The program is free, but the word list has to be bought. It has free alternative word lists that you can use. Visit the product website https://www.openwall.com/john/ for more information and how to use it.
Winxp img bochs download. Cain & Abel
Cain & Abel runs on windows. It is used to recover passwords for user accounts, recovery of Microsoft Access passwords; networking sniffing, etc. Unlike John the Ripper, Cain & Abel uses a graphic user interface. It is very common among newbies and script kiddies because of its simplicity of use. Visit the product website https://www.softpedia.com/get/Security/Decrypting-Decoding/Cain-and-Abel.shtml for more information and how to use it.
Ophcrack
Ophcrack is a cross-platform Windows password cracker that uses rainbow tables to crack passwords. It runs on Windows, Linux and Mac OS. It also has a module for brute force attacks among other features. Visit the product website https://ophcrack.sourceforge.io/ for more information and how to use it.
Password Cracking Counter Measures
- An organization can use the following methods to reduce the chances of the passwords been cracked
- Avoid short and easily predicable passwords
- Avoid using passwords with predictable patterns such as 11552266.
- Passwords stored in the database must always be encrypted. For md5 encryptions, its better to salt the password hashes before storing them. Salting involves adding some word to the provided password before creating the hash.
- Most registration systems have password strength indicators, organizations must adopt policies that favor high password strength numbers.

Zastone uv-8dr manual. My customer wanted to know if Office 2016 copy was activated correctly on one of their computers. The story why it was necessary is told below.
Did Your Office 2016 or Office 2016 License Successfully Activate?
After the installation and activation of Office 2016 or Office 365 on your computer, you can make sure that your Office copy is activated correctly in the command prompt using ospp.vbs script included in Office.
First of all, you need to know the bitness of your Office (32- or 64-bit). To do it, start any Office program (Word, Excel, Outlook) and select File -> Office account -> About. In the next window the bitness of your copy will be shown. (In our example, it is 32-bit.)
Run the command prompt with the administrator privileges and go to the directory, which path depends on the bitness and versions of your Windows and Office:
- If you are using Windows x64 and Office 32-bit (the most typical case):
CD %SystemDrive%Program Files (x86)Microsoft OfficeOffice16 - Windows x86 and Office 32-bit:
CD %SystemDrive%Program FilesMicrosoft OfficeOffice16 - Windows x64 and Office 64-bit:
CD %SystemDrive%Program FilesMicrosoft OfficeOffice16
Check Office activation status with the following command:
cscript ospp.vbs /dstatus
According to the information the tool provides, this Office2016 copy is activated (LICENSE STATUS: —LICENSED—) on the KMS server (KMS machine name) using the GVLK for Office 2016 Pro Plus (Last 5 characters of installed product key). The license will be active for 176 days (REMAINING GRACE). If the KMS server is available, the license is automatically renewed for 180 days every 7 days (KMS Activation FAQ).

Removing Office 2016 Activation Window: Let’s Get Started
As we have seen earlier, the version of Office 2016 installed on this computer is activated, however when trying to start any Office products the following window appears:
Let’s get startedChoose one
- Try – Get a free trial of Office 365
- Buy – Buy Office from the Microsoft Store
- Activate – Enter you Product Key or sign in
You can close this window that doesn’t restrict any Office features, but it appears every time when you start any of the products, that is terribly annoying. I could find out how to remove this activation window.
As it turned out the problem is related to the preinstalled Office 365 that had been uninstalled to install Office 2016 instead. I tried to use the removal tools offered on Microsoft website to remove this window, but they didn’t help.
The only feasible way was to remove the registry key (depending on the bitness of the system):
- HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftOffice16.0CommonOEM
- HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonOEM
It is faster to do it in PowerShell:
Remove-Item –Path “HKLM:SOFTWAREWow6432NodeMicrosoftOffice16.0CommonOEM” –Recurse
Remove-Item –Path “HKLM: SOFTWAREMicrosoftOffice16.0CommonOEM” –Recurse
Just close all Office applications and start them again. The Office activation notification will disappear.
