Computer software, or simply software, is a generic term that refers to a collection of data or computer instructions that tell the computer how to work, in contrast to the physical hardware from which the system is built, that actually performs the work.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.

Software cracking (known as "breaking" in the 1980s) is the modification of software to remove or disable features which are considered undesirable by the person cracking the software, especially copy protection features (including protection against the manipulation of software, serial number, hardware key, date checks and disc check) or software annoyances like nag screens and adware.

In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm.

For encryption algorithms, a key specifies the transformation of plaintext into ciphertext, and vice versa for decryption algorithms.

Keys also specify transformations in other cryptographic algorithms, such as digital signature schemes and message authentication codes.
