    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 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 ...

  3. Software cracking - Wikipedia

    en.wikipedia.org/wiki/Software_cracking

    Software cracking (known as "breaking" mostly in the 1980s [ 1]) is an act of removing copy protection from a software. [ 2] Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software generally involves ...
