Product Key
A product key, also known as a software key, serial key or activation key, is a specific software-based key for a computer program. It certifies that the copy of the program is original. Product keys consist of a series of numbers and/or letters. This sequence is typically entered by the user during the installation of computer software, and is then passed to a verification function in the program. This function manipulates the key sequence according to a mathematical algorithm and attempts to match the results to a set of valid solutions. Effectiveness Standard key generation, where product keys are generated mathematically, is not completely effective in stopping copyright infringement of software, as these keys can be distributed. In addition, with improved communication from the rise of the Internet, more sophisticated attacks on keys such as cracks (removing the need for a key) and product key generators have become common. Because of this, software publishers use additio ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Software License Server
A software license server is a centralized computer software system which provides access tokens, or keys, to client computers in order to enable licensed software to run on them. In 1989, Sassafras Software Inc developed their trademarked KeyServer software license management tool. Since that time, other computing technology firms have adopted the phrase "key server" to be used interchangeably with "software license server." It is the job of a software license server to determine and control the number of copies of a program permitted to be used based on the license entitlements that an organization owns. Typically, an end-user customer organization will install a software license server on a host computer to provide licensing services to an enterprise computing environment. Publisher-specific license servers are commonly provided by software publishers, or through third party providers, to manage software licensing for a specific software publisher's products. Publisher-s ...

Serial Number
A serial number is a unique identifier assigned incrementally or sequentially to an item, to ''uniquely'' identify it. Serial numbers need not be strictly numerical. They may contain letters and other typographical symbols, or may consist entirely of a character string. Applications of serial numbering Serial numbers identify otherwise identical individual units, thereby serving various practical uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected. Some items with serial numbers are automobiles, firearms, electronics, and appliances. Smartphones and other S ...

Product Activation
Product activation is a license validation procedure required by some proprietary software programs. Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it ''determines'' whether it is authorized to fully function. Activation allows the software to stop blocking its use. An activation can last "forever", or it can have a time limit, requiring a renewal or re-activation for continued use. Implementations In one form, product activation refers to a method invented by Ric Richardson and patented () by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to generate a unique installation ID. This installation ID is sent to the manufacturer to verify the authenticity of the product key and to ensure that the product key is not being used for multiple installations. Alternatively, the software vendor sends the user a unique ...

License Manager
A software license manager is a software management tool used by Independent software vendors or by end-user organizations to control where and how software products are able to run. License managers protect software vendors from losses due to software piracy and enable end-user organizations to comply with software license agreements. License managers enable software vendors to offer a wide range of usage-centric software licensing models, such as product activation, trial licenses, subscription licenses, feature-based licenses, and floating licensing from the same software package they provide to all users. A license manager is different from a software asset management tool, which end-user organizations employ to manage the software they have licensed from many software vendors. However, some software asset management tools include license manager functions. These are used to reconcile software licenses and installed software, and generally include device discovery, soft ...

Intel Upgrade Service
The Intel Upgrade Service was a relatively short-lived and controversial program of Intel that allowed some low-end processors to have additional features unlocked by paying a fee and obtaining an activation code that was then entered in a software program, which ran on Windows 7. The program was introduced in September 2010 for the Clarkdale-based Pentium G6951 desktop processor (operating at 2.8 GHz), and immediately met with criticism from the specialist press. For a $50 fee, this processor could have one additional megabyte of cache enabled, as well hyper-threading, making it almost like the Core i3-530, except for the slightly lower frequency that remained unchanged—the i3-530 operated at 2.93 GHz. The official designation for the software-upgraded processor was Pentium G6952. In order for the activation software to work, the motherboard had to have the DH55TC or DH55PJ chipset. One reviewer noted that at the market price of the time one could actually buy the i ...

Cryptographic Hash Function
A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of n bits) that has special properties desirable for cryptography: * the probability of a particular n-bit output result (hash value) for a random input string ("message") is 2^ (like for any good hash), so the hash value can be used as a representative of the message; * finding an input string that matches a given hash value (a ''pre-image'') is unfeasible, unless the value is selected from a known pre-calculated dictionary (" rainbow table"). The ''resistance'' to such search is quantified as security strength, a cryptographic hash with n bits of hash value is expected to have a ''preimage resistance'' strength of n bits. A ''second preimage'' resistance strength, with the same expectations, refers to a similar problem of finding a second message that matches the given hash value when one message is already known; * finding any pair of different messa ...

Biometric Passport
A biometric passport (also known as an e-passport or a digital passport) is a traditional passport that has an embedded electronic microprocessor chip which contains biometric information that can be used to authenticate the identity of the passport holder. It uses contactless smart card technology, including a microprocessor chip (computer chip) and antenna (for both power to the chip and communication) embedded in the front or back cover, or centre page, of the passport. The passport's critical information is printed on the data page of the passport, repeated on the machine readable lines and stored in the chip. Public key infrastructure (PKI) is used to authenticate the data stored electronically in the passport chip, making it expensive and difficult to forge when all security mechanisms are fully and correctly implemented. Many countries are moving towards issuing biometric passports to their citizens. Malaysia was the first country to issue biometric passports in 1998. I ...

Cedega (software)
Cedega (formerly known as WineX) was the proprietary fork by TransGaming Technologies of Wine (software), Wine, from the last version of Wine (software), Wine under the X11 license before switching to GNU Lesser General Public License, GNU LGPL. It was designed specifically for running personal computer game, games created for Microsoft Windows under Linux. As such, its primary focus was implementing the DirectX application programming interface, API. WineX was renamed to Cedega on the release of version 4.0 on June 22, 2004. Cedega Gaming Service was retired on February 28, 2011. TransGaming announced that development would continue under the GameTree Linux Developer Program, however this proved moot as the company's core technology divisions were shuttered in 2016. Licenses Though Cedega was mainly proprietary software, TransGaming did make part of the source publicly available via Concurrent Versions System, CVS, under a mix of licenses. Though this was mainly done to allow a me ...

Wine (software)
Wine (formerly a recursive backronym for ''Wine Is Not an Emulator'', now just "Wine") is a free and open-source compatibility layer that aims to allow application software and computer games developed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, named ''Winelib'', against which developers can compile Windows applications to help port them to Unix-like systems. Wine provides its compatibility layer for Windows runtime system (also called runtime environment) which translates Windows API calls into POSIX API calls, recreating the directory structure of Windows, and providing alternative implementations of Windows system libraries, system services through wineserver and various other components (such as Internet Explorer, the Windows Registry Editor, and msiexec). Wine is predominantly written using black-box testing reverse-engineering, to avoid copyright issues. The selection of "Wine is Not an Emulator" as the name of t ...
