Percent-encoding. 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. Although it is known as URL encoding, it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both ...

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...
