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. Cryptography is a field of knowledge which uses a mathematical equation to perform the encryption and decryption process.
