The bitting code is used in conjunction with a key's Depth and Spacing Number to completely determine all relevant information regarding the key's geometry. [1] Each number in the bitting code corresponds to a cut on the key blade. For example, a bitting code of 11111 with Depth and Spacing Number 46 specifies a Kwikset key with five shallow cuts.
For example, master keyed pin tumbler locks often have two shear points at each pin position, one for the change key and one for the master key. A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Master keyed lock systems generally reduce overall security. [2]
Master may be used to mean a copy that has more significance than other copies in which case the term is an absolute concept; not a relationship. Sometimes the term master-slave is used in contexts that do not imply a controlling relationship. In database replication, the master database is the authoritative source. A replica database ...
master key - key from which all other keys (or a large group of keys) can be derived. Analogous to a physical key that can open all the doors in a building. master encryption key (MEK) - Used to encrypt the DEK/TEK key. master key encryption key (MKEK) - Used to encrypt multiple KEK keys. For example, an HSM can generate several KEK and wrap ...
Data Protection Application Programming Interface (DPAPI) is a simple cryptographic application programming interface available as a built-in component in Windows 2000 and later versions of Microsoft Windows operating systems. In theory, the Data Protection API can enable symmetric encryption of any kind of data; in practice, its primary use in ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
The syntax of a computer program is a list of production rules which form its grammar. [96] A programming language's grammar correctly places its declarations, expressions, and statements. [97] Complementing the syntax of a language are its semantics. The semantics describe the meanings attached to various syntactic constructs. [98]
A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
