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 was designed in 1995 by Patrick Juola, a computational linguist, and Philip Zimmermann, creator of PGP. [1][2] The words were carefully chosen for their phonetic distinctiveness, using genetic algorithms to select lists of words that had optimum separations in phoneme space.

The applied barcode uses printed and non-printed bars spaced 3 mm apart, and consists of two fields. The rightmost field, which is 27 bars in width, encodes the destination postal code. The leftmost field is 9 bars in width and applied right below the printed destination address. It is currently unclear what this field is used for. In the postal co...
Disregarding the space, divide the postal code into four subfields (e.g. K1-A-0-B1).Locate the contents of each subfield in the encoding tables below and record the hexadecimal numbers that they correspond to. (e.g. K1-A-0-B1 becomes 32-07-A-C2.)Convert those hex numbers to binary, and add leading zeroes where required.Change the binary numbers into bars. "Zero" bits in the resulting binary numbers correspond to spaces in the barcode, while "one" bits correspond to printed bars, with the least significant bit of...Note that postal codes use only 20 letters; six letters (D, F, I, O, Q, U) are never used. Unused codepoints are indicated with dashes. No field begins or ends with more than three consecutive 1 bits, guaranteeing that there are never more than six consecutive 1 bits. Guaranteeing the five-bit limit on consecutive 0 bits is achieved by limiting the...
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.
