  2. Identification key - Wikipedia

    en.wikipedia.org/wiki/Identification_key

    In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains.

  3. Computer keyboard - Wikipedia

    en.wikipedia.org/wiki/Computer_keyboard

    History. Typewriters are the definitive ancestor of all key-based text entry devices, but the computer keyboard as a device for electromechanical data entry and communication largely comes from the utility of two devices: teleprinters (or teletypes) and keypunches. It was through such devices that modern computer keyboards inherited their layouts.

  4. Advanced Encryption Standard - Wikipedia

    en.wikipedia.org/wiki/Advanced_Encryption_Standard

    The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001.

  5. Hardware security module - Wikipedia

    en.wikipedia.org/wiki/Hardware_security_module

    An internal HSM in PCIe format. A hardware security module ( HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys ), performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1] These modules traditionally come in the form of a ...

  6. Key size - Wikipedia

    en.wikipedia.org/wiki/Key_size

    In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by brute-force ...

  7. Passphrase - Wikipedia

    en.wikipedia.org/wiki/Passphrase

    NIST has estimated that the 23-character passphrase "IamtheCapitanofthePina4" contains a 45-bit strength. The equation employed here is: [4] 4 bits (1st character) + 14 bits (characters 2–8) + 18 bits (characters 9–20) + 3 bits (characters 21–23) + 6 bits (bonus for upper case, lower case, and alphanumeric) = 45 bits.

  8. Product key - Wikipedia

    en.wikipedia.org/wiki/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.

  9. Key (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Key_(cryptography)

    A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on ...

  10. Key frame - Wikipedia

    en.wikipedia.org/wiki/Key_frame

    Key frame. In animation and filmmaking, a key frame (or keyframe) is a drawing or shot that defines the starting and ending points of a smooth transition. These are called frames because their position in time is measured in frames on a strip of film or on a digital video editing timeline. A sequence of key frames defines which movement the ...

  11. Turnkey - Wikipedia

    en.wikipedia.org/wiki/Turnkey

    Turnkey refers to something that is ready for immediate use, generally used in the sale or supply of goods or services. The word is a reference to the fact that the customer, upon receiving the product, just needs to turn the ignition key to make it operational, or that the key just needs to be turned over to the customer.
