Keygen
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 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, where keygens are often accompanied with chiptunes and artistic visual representations. ==Software licensing== A software license is a legal instrument that governs the usage and distribution of computer software.〔http://web.archive.org/web/20110514103947/http://knol.google.com/k/jon-gillespie-brown/what-is-software-licensing/3v64x901bjfe2/2# What is Software licensing?〕 Often, such licenses are enforced by implementing in the software a product activation or digital rights management (DRM) mechanism,〔http://web.archive.org/web/20111121001926/http://knol.google.com/k/why-product-activation-for-software-is-becoming-widespread#〕 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.
