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 ...
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 ...
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 ...
A key generator [1] [2] [3] is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate ...
Keys are used to control the operation of a cipher so that only the correct key can convert encrypted text to plaintext.All commonly-used ciphers are based on publicly known algorithms or are open source and so it is only the difficulty of obtaining the key that determines security of the system, provided that there is no analytic attack (i.e. a "structural weakness" in the algorithms or ...
The Open Source Initiative (OSI) is one such organization keeping a list of open-source licenses. [ 1] The Free Software Foundation (FSF) maintains a list of what it considers free. [ 2] FSF's free software and OSI's open-source licenses together are called FOSS licenses. There are licenses accepted by the OSI which are not free as per the Free ...
Sybase Open Watcom Public License. Released as Open Watcom, under a license which is considered free by the OSI [68] but not by the FSF. The FSF has problems with the license as it demands more freedom than the GPL by requiring the release of source code also in the case of private use. [69] Xerox Alto.
A cryptographically secure pseudorandom number generator ( CSPRNG) or cryptographic pseudorandom number generator ( CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also referred to as a cryptographic random number generator ( CRNG ).
