Difference Between Crack and Keygen

Cracks and keygens, vastly used but rarely known. In the world of computers and software, we often use these terms in application works but we do not know what they mean and what fine differences both the terms contain. Keygens, sometimes described as “key generators,” are tiny utility applications that create product authorization keys and are coded numerically. While the cracks may seem similar in certain cases, they are not identical.

So, this article will help you understand the meanings, features, and differences amongst the two terms which are very popular in the piracy and authorization sector of computers and networking.

Crack vs Keygen

The main difference between crack and keygen is that a crack is a technique used for bypassing the coded authorization protocol of a program or application which is also well recognized as a pirated softcopy of the original software. And, a keygen is a simpler application or rather an algorithm that helps in generating the authorization code for a premium service or an application. Both the techniques require a professional approach and the keygens of the new era can practically generate every code after a couple of trial runs.

Crack vs Keygen

A crack is a program that cracks the encryption of a piece of software in order to extend the trial time or to permanently unlock the encrypted premium content. Assume a program offers a 15-day trial period. By breaking and modifying the program code, the cracker for that product can prolong the 15-day trial phase restriction to anything like 365 or 365 days or even years!

A crack is a supplementary software that must be performed after the primary software has been installed. The crack instructs the users to look in the File Management folder on the C: drive of the Windows Operating system for the primary program deployment folder and the primary software file included within that directory which can sometimes be hidden by default by the OS. It modifies the script and increases the trial duration of that particular application.

A keygen on the other hand is a generation algorithm mostly embedded in independent websites which charge revenue for each code. The rate of efficiency of keygen software and programs is not as high as that of a developed patch but it surely is reliable. Since the user has unlawfully downloaded the software and requires a key to install it on their system, keygens are frequently employed in illegal downloading. The keygens working mechanism is simple and scarily effective as well!

Comparison Table Between Crack and Keygen

Parameters of ComparisonCrackKeygen
Drive TypeA crack can be independently uploaded, utilized offline as well as require an independent external drive to access the save-point of the original file.A keygen usually is available in two modes and always requires an internet connection. It follows a simple hit and trial method with unadvised interconnection status.
EffectivenessThey are very effective and long lasting.Not effective as the success rate of generating a correct code is less.
UtilityFor extension of the trial-version and breaking the security barriers of a premium program.To generate coupon codes and product utilization one time code.
Program TypeIt is an infiltration and forgery software. It works on the mechanism of a dictionary generator.It is a simple programme that works on the hit and trial principle.
ExamplesCracked Windows OS, Cracked Photoshop and other Adobe softwares.Kygen generator for wizards, cryptolocker is a malware keygen.

What is Crack?

A crack is a way of gaining access to a protected computing device. It was created in the 1980s by programmers who sought to distance themselves from some of the more nefarious hacking activities. The primary aim of a cracker is to sneak into a system and derive satisfaction from just being able to “crack” the system’s perimeter fence.

Basically crack is a credential cracking application for Unix systems. It was created with the goal of allowing sysadmins to discover users whose keys are insufficiently weak to withstand a vocabulary hacking attempt. Alec Muffet, the system’s inventor, sought to enhance the program’s forerunner, a ‘pwc’ breaker in COPS. Muffet was able to improve the project’s performance by simply re-engineering the data storage.

The crack was initially uploaded to the Usenet communities data supports and alternative barrier as edition 2.7a. Following updates included a slew of additional features, including a customizable “dictionary generator”, a network-based password monitoring system, and better code with far more versatility than previous versions. By including a customizable dictionary generator into the platform, the user will be able to enforce logic to the standard dictionary set of words to produce customized versions of the words included within.

Cracks are most commonly used for applications that do not frequently access the internet, such as multimedia converters, editing applications, premium applications with paid services, and games too.

What is Keygen?

The shortened version of the term key generator is keygen. It’s a little type of tech that produces valid CD codes or sequential (activation) codes mainly numeric or alphanumeric. These serial codes are made accessible to managers for free via distribution on a variety of websites devoted to digital piracy by program cracking groups. Activating software without acquiring the authentic code is deemed illegal in several countries.

A “disassembler” is used to slip into something and examine the raw bytecode of the targeted application, which is how keygen works. Sometimes this looks for the needed code in the application or the installation. The position and subroutine(s) necessary for testing the accuracy of a string are easily discovered after the client has obtained access to the computer program.

The basic task of a disassembler is a program that transforms a platform’s programming languages into assembler codes. Assembly language is a computer language that shortens functions and procedures so that developers can memorize or understand how a piece of application functions.

This makes it possible to reverse analyze the method and generate valid keys. The catch is that the keys discovered will or will not work with online applications The catch is that the keys discovered will or will not work with online applications since the server has direct knowledge about every accessible user and their method of logging in.

Main Differences Between Crack and Keygen

  1. Crack breaks the security accessing component of software whereas keygen is a simple code generator
  2. Cracked software lasts longer than keygen originated software because it is directly connected to the servers.
  3. Crack is a complex algorithmic process whereas keygen works on simple hit-and-trial methods.
  4. Crack is also known as pirated software whereas a keygen unlocked application is often called a generated program.
  5. The efficiency of cracking software because it includes the dictionary generator is more than relying upon keygen code origin.


Additions to Crack also provide a customizable dictionary generator and a networking spread password tracking mechanism; Keygen works in a straightforward method, but may not give working keys every time in every attempt. The cracking procedure has more success rate than the key generation but it requires good reasoning and IT skills as well.

Both the techniques i.e. cracking and keygen unlocking are considered to be illegal and unlawful. The reason why they are unlawful is that tampering with the copyright rights and material distribution without the consent of the owner is an unlawful offense in most countries.
