Crypto chip / The Codestar module add-on board

Obraz
The CodeStar module was designed for encryption and decryption of information for personal computers. The board was inserted into a free computer slot and occupied one 8-bit bus slot of a PC, XT, AT class computer. The module was supplied with a floppy disk with files in the Turbo C++ language under the MS-DOS OS . The original CRY 8 customer circuit, based on reliable technology had the entire information encryption and decryption algorithm hidden. This algorithm ( Feistel -type algorithm) was developed and manufactured in Switzerland for reliability on a special order basis, together with a semi-custom integrated circuit using CMOS VLSI technology. The order was placed by the Institute of Computer Systems of the Slovak Academy of Sciences (today‘s Institute of Informatics SAV ). The module was used to encrypt and decrypt the user's information or the user's entire file with an original and constantly changing key, it served to protect the user's data from unauthor...

Takto, ako poukázal, Mojžiš sám nariadil aby sa zhotovil podľa vzoru viditeľného sveta. Túto svoju teóriu predstavil v knihe ' Kresťanská Topografia - Topographia Christiana '. V jej úvode píše: 'Poďme ďalej mojich čitateľov vyzvať aby preskúmali náčrt vesmíru a pohybov hviezd, ktoré sme si pripravili ako prezentáciu organickej sféry pohanov a preštudovali si jej popis poslaný zb...
