Design criteria. The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability. The Rijndael S-box can be replaced in the Rijndael cipher ...
As of January 2024, it is used by 36% of websites and supported by almost all web browsers (over 98% of users). It is also supported by major web servers over Transport Layer Security (TLS) using an Application-Layer Protocol Negotiation (ALPN) extension
History and structure The PGP Word List was designed in 1995 by Patrick Juola, a computational linguist, and Philip Zimmermann, creator of PGP. The words were carefully chosen for their phonetic distinctiveness, using genetic algorithms to select lists of words that had optimum separations in phoneme space. space.
UTF-8 is a variable-length character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [1] UTF-8 is capable of encoding all 1,112,064 [a] valid Unicode code points using one to four one- byte (8-bit) code units.
This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.
The English Opening is a chess opening that begins with the move: 1. c4. A flank opening, it is the fourth most popular [1] [2] and, according to various databases, one of the four most successful of White's twenty possible first moves.
A blockchain is a distributed ledger with growing lists of records ( blocks) that are securely linked together via cryptographic hashes. [1] [2] [3] [4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).
