A key generator (key-gen) is a computer program that generates a product licensing key, such as a serial number, necessary to activate for use of a software application. Keygens may be legitimately distributed by software manufacturers for licensing software in commercial environments where software has been licensed in bulk for an entire site or enterprise, or they may be distributed illegitimately in circumstances of copyright infringement or software piracy. Illegitimate key generators are typically distributed by software crackers in the warez scene and demoscene. These keygens often play 'Keygen music', which may include the genres dubstep or chiptunes[1] in the background and have artistic user interfaces.
A software license is a legal instrument that governs the usage and distribution of computer software.[2] Often, such licenses are enforced by implementing in the software a product activation or digital rights management (DRM) mechanism,[3] seeking to prevent unauthorized use of the software by issuing a code sequence that must be entered into the application when prompted or stored in its configuration.[better source needed]
Many programs attempt to verify or validate licensing keys over the Internet by establishing a session with a licensing application of the software publisher. Advanced keygens bypass this mechanism, and include additional features for key verification, for example by generating the validation data which would otherwise be returned by an activation server. If the software offers phone activation then the keygen could generate the correct activation code to finish activation. Another method that has been used is activation server emulation, which patches the program memory to 'see' the keygen as the de facto activation server.
A multi-keygen is a keygen that offers key generation for multiple software applications. Multi-keygens are sometimes released over singular keygens if a series of products requires the same algorithm for generating product keys. In this case, only a single value encoded within the key has to be changed in order to target a different product.
Unauthorised keygens that typically violate software licensing terms are written by programmers who engage in reverse engineering and software cracking, often called crackers, to circumvent copy protection of software or digital rights management for multimedia.
Keygens are available for download on warez sites or through peer-to-peer (P2P) networks.
Many unauthorised keygens, available through P2P networks or otherwise, contain malicious payloads.[4] These key generators may or may not generate a valid key, but the embedded malware loaded invisibly at the same time may, for example, be a version of CryptoLocker (ransomware).[5][6]
Autocad 2017 free download. Antivirus software may discover malware embedded in keygens; such software often also identifies unauthorised keygens which do not contain a payload as potentially unwanted software, often labelling them with a name such as Win32/Keygen or Win32/Gendows.[4]
A key changer or keychan is a variation of a keygen. A keychan is a small piece of software that changes the license key or serial number of a particular piece of proprietary software installed on a computer.
A key generator, often shortened to 'keygen,' is a program that creates unique, working product keys for software programs and operating systems.
Most software programs require a product key or some other kind of installation code before you can use the program, so having a tool that actually creates them would no doubt save you lots of money, especially if you've already paid for the program but lost the installation code.
Keygens go by many names, including 'product key generators,' 'CD key creators,' 'license key generators,' etc. No matter the name, all key generators create free, unique product keys for various software programs, video games, etc.
Unfortunately, like with most free things, there's a catch.
The short answer: absolutely not. A keygen is not a good way to get create that installation key you need for your software or operating system.
A key generator may create a product key that your software will accept, but it will not find your product key.
Product keys created by key generators are not legal installation keys. The only legal way to obtain a product key is by purchasing the software yourself or by contacting the software maker directly to obtain a key.
No matter which key generator you might use, or where you download it from, using a product key other than the unique one that comes with an individual, legally purchased copy of a software title is illegal. Using a product key not issued by the software developer is certainly a violation of the agreement you make when you use the software.
Requiring a valid, unique product key is a software company's way of ensuring that each copy of their program is used only once and that each customer is paying for each copy used.
The key generators you find online work similarly to the back-end tools that software makers use to generate legitimate product keys via a proprietary algorithm.
What a keygen creator has done to make a program that duplicates this proprietary software is either a) steal this software from the company, or b) reverse engineer the algorithm using a collection of valid product keys that he or she has obtained, probably illegally.
Sometimes, depending on the complexity of the program, the keygen comes packaged with one or more DLL or EXE files with the intention that they're written over the legitimate, original files so that the keygen will work properly.
Regardless of how, the end result is the same — key generators are not a legal, or ethical (in my opinion), a way of obtaining a key code to use for installing a piece of software.
If you have a legal copy of a program that you've already entered a valid CD key into, but you've just lost the key, try a free product key finder program to locate the product key from your currently installed copy of the program.
This is a perfectly legal method of obtaining a product key because it's the same one you purchased when you first installed the program.
