The randomice text will devivided into 2 blocks which 32-bits in length. Next step, the deviding text will be permutated using first permutation matrix, the goal is to randomice plaintext. Its means automatically that in DES algorithm using 8-characters or 64-bits. The changing file as binary will be devided into 64 bits. This file contents will be changed as binery numbers using ASCII as reference. The steps in doine encryption will begin with choosing file. The next we will to do enription process. Because in this application we have designed internal key altogether in enription process. The first proces will generate DES key algorithm. The messages will be randomly using standard matrix in DES alhgorithm.
The principt of DES working is devides information in special blocks, so that DES is known as cipherblock. Even government organitations in US like Departmen of Energy, Justice Department, and Federal Reserve System are using DES to protect their data desiminations.
In every day live, DES is using in many applications like to encrypt PIN (Personal Identity Number) in ATM and Banking transactions via internet. Since that, DES has been used in desimination information widely to protect data savely. DES algorithm is adopted as standard algorithm. This application will implementing the way of encryption and decription using DES. This cryptographic applications implementing encryption and decryption method using the DES algorithm.This research will presenting application design of crioptographic and its algorithm data of DES. In this final project will be presented the design of cryptographic applications with cryptographic algorithm Data Encryption Standard. This technique is used to convert the data into a specific code, with the aim that the stored information can not be read by anyone except those who are eligible.

In order to overcome this problem, the author applies the apostolico-giancarlo algorithm to the application of mobile-based sports terms that can facilitate the information search process, compared to those who still have to search for books which require a relatively long time in searching for the meaning of sport. The application design process carried out is still difficult to find the meaning of certain sports terms in sports. Especially in the development of sports in information technology. In this era of globalization, it is very necessary to have an information system that is fast and ready to use due to increasingly sophisticated human civilization and humans themselves are required to be able to adapt to these developments.
