A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters. The 7-track magnetic tape format was ...
LogMeIn Hamachi is a virtual private network (VPN) application developed and released in 2004 by Alex Pankratov. [2] [3] It is capable of establishing direct links between computers that are behind network address translation (NAT) firewalls without requiring reconfiguration (when the user's PC can be accessed directly without relays from the ...
Stream cipher. The operation of the keystream generator in A5/1, an LFSR-based stream cipher used to encrypt mobile phone conversations. A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the ...
Formats for license plate numbers are consistent within the state. For example, Delaware is able to use six-digit all-numeric serials because of its low population. Several states, particularly those with higher populations, use seven-character formats of three letters and four digits, including 1ABC234 in California, 1234ABC in Kansas and ABC-1234 (with or without a space or dash) in Georgia ...
A de Bruijn sequence can be used to shorten a brute-force attack on a PIN -like code lock that does not have an "enter" key and accepts the last n digits entered. For example, a digital door lock with a 4-digit code (each digit having 10 possibilities, from 0 to 9) would have B (10, 4) solutions, with length 10 000.
A Wordlock letter combination lock.. A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an ...
Computer number format. A computer number format is the internal representation of numeric values in digital device hardware and software, such as in programmable computers and calculators. [1] Numerical values are stored as groupings of bits, such as bytes and words. The encoding between numerical values and bit patterns is chosen for ...
The International Bank Account Number ( IBAN) is an internationally agreed upon system of identifying bank accounts across national borders to facilitate the communication and processing of cross border transactions with a reduced risk of transcription errors. An IBAN uniquely identifies the account of a customer at a financial institution. [1]
