Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover ( NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed. Keyboards that lack full rollover will register an incorrect keystroke ...
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 ...
AACS encryption key controversy. Internet users began circulating versions of this image, calling it the Free Speech Flag, in blog posts on dozens of websites and as user avatars on forums such as Digg. The first fifteen bytes of the 09 F9 key are contained in the RGB encoding of the five colors, with each color providing three bytes of the key.
It was possible to remove the second _NSAKEY: when loading a cryptographic module, the crypto_verify first tries using _KEY to verify the module, then goes to _NSAKEY if the first key fails. Since no known cryptographic modules in Windows are signed with _NSAKEY, it never gets used. Replacing the key with a different key allows non-US companies ...
Super key (keyboard button) A Super key, located between the Control key and the Alt key, on an ISO style PC keyboard. Super key ( ) is an alternative name for what is commonly labelled as the Windows key [ 1] or Command key [ 2] on modern keyboards, typically bound and handled as such by Linux and BSD operating systems and software today.
The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interfaces can all use the registry. The registry also allows access to counters for profiling ...
The Windows logo key (also known as Windows, win, start, logo, flag or super[ 1] key) is a keyboard key which was originally introduced on Microsoft 's Natural Keyboard in 1994. Windows 95 used it to bring up the start menu and it then became a standard key on PC keyboards. Ctrl + Esc performs the same function, in case the keyboard lacks this key.
Modifier key. In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together. By themselves, modifier keys usually do nothing; that is, pressing any of the ⇧ Shift, Alt, or Ctrl keys alone does not (generally) trigger any action from the ...
