The Rijndael S-box is a substitution box ( lookup table) used in the Rijndael cipher, on which the Advanced Encryption Standard (AES) cryptographic algorithm is based. [1] Forward S-box. 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).
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.
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems.

When contrasted with other blocks containing CJK Unified Ideographs, it is also referred to as the Unified Repertoire and Ordering (URO).[3] The block has hundreds of variation sequences ...
A competing encoding technique, used for the ISDN basic rate interface where 4B3T is not used, is 2B1Q . The sync sequence used is the 11-symbol Barker code, +++−−−+−−+− or its reverse, −+−−+−−−+++. Encoding table. Each 4-bit input group is encoded as a 3-symbol group (transmitted left to right) from the following table.
Western Latin character sets (computing) Several 8-bit character sets (encodings) were designed for binary representation of common Western European languages ( Italian, Spanish, Portuguese, French, German, Dutch, English, Danish, Swedish, Norwegian, and Icelandic ), which use the Latin alphabet, a few additional letters and ones ...
