Hexspeak is a novelty form of variant English spelling using the hexadecimal digits. Created by programmers as memorable magic numbers, hexspeak words can serve as a clear and unique identifier with which to mark memory or data.
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 ...
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. This sequence is typically entered by the user during the installation of computer ...
The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form: $2<a/b/x/y>$[cost]$[22 character salt][31 character hash] For example, with input password abc123xyz, cost 12, and a random salt, the output of bcrypt is the string.
Blowfish has a 64-bit block size and a variable key length from 32 bits up to 448 bits. [5] It is a 16-round Feistel cipher and uses large key-dependent S-boxes. In structure it resembles CAST-128, which uses fixed S-boxes. The adjacent diagram shows Blowfish's encryption routine. Each line represents 32 bits.
Universally unique identifier. A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. The term Globally Unique Identifier (GUID) is also used, mostly in Microsoft systems. [1][2] When generated according to the standard methods, UUIDs are, for practical purposes, unique.
A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys —such as Esc and Break —for special actions, and often a numeric keypad to facilitate calculations. [2][3] There is some variation between different keyboard ...
The key space increases by a factor of 2 for each additional bit of key length, and if every possible value of the key is equiprobable; this translates into a doubling of the average brute-force key search time with every additional bit of key length.
