URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI.
Taiwan,[II][k] officially the Republic of China (ROC),[I][l] is a country[27] in East Asia.[o] It is located at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ...

The S-box maps an 8-bit input, c, to an 8-bit output, s = S(c). Both the input and output are interpreted as polynomials over GF(2). First, the input is mapped to its multiplicative inverse in GF(28) = GF(2) [x]/(x8 + x4 + x3 + x + 1), Rijndael's finite field. Zero, as the identity, is mapped to itself. This transformation is known as the Nyberg S-...
The inverse S-box is simply the S-box run in reverse. For example, the inverse S-box of b816 is 9a16. It is calculated by first calculating the inverse affine transformation of the input value, followed by the multiplicative inverse. The inverse affine transformation is as follows: 1. [ b 0 b 1 b 2 b 3 b 4 b 5 b 6 b 7 ] = [ 0 0 1 0 0 1 0 1 1 0 0 1 ...
The Rijndael S-box was specifically designed to be resistant to linear and differentialcryptanalysis. 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,which defeats the sus...
From Wikipedia, the free encyclopedia. Algebraic notation is the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the board. [1] . It is used by most books, magazines, and newspapers.
v. t. e. This table of bases gives the values of 0 to 257 in bases 2 to 36, using A−Z for 11−36. "Base" (or "radix") is a term used in discussions of numeral systems which use place-value notation for representing numbers . Base 10 is in bold . All 10s are in italic . base 2. base 3.
The of a star is a short code primarily summarizing the state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters , a sequence from the hottest ( type) to the coolest ( type).
PGP word list. The PGP Word List (" Pretty Good Privacy word list", also called a biometric word list for reasons explained below) is a list of words for conveying data bytes in a clear unambiguous way via a voice channel.
