Using cryptographic metods in private communication via sockets and an application

The advantage of Development of Technology are facilitated human activities. Along this advantages appeared disadvantages. These disadvantages are led to development Seceure Sistems of technology. The technology disadvantages are considered by overlooked errors, value of algorithm complexity. Any disadvantages are occured along side of distributing the working principle of technology, also misuse rate will be increase. For these reason protect to these technologies are being developed safe systems. One of the safe systems are the Criptpographic systems. Cryptography using every technology systems for secure. Cryptography also using in electronic communication. Thanks to cryptography, pairs can communicate safely. In this Dessertation are reserched history of Cryptography, current Cryptography sistems which use in modern technology. Based on advanced Cryptographic sistems this dessertation project use Rijndeal algorithm and make this communication safely against atackers. In this project when pairs are during communication over the insecure channel, this channel are eavedropping from passive attacker. The purpose of this project is make commination safely. To make communication safely, pairs must communicate by Rijndeal cryptographic algorithm. Other purpose of this project is attacker shouldn't suspect in this communication using cryptographic techniques. For this reason pairs must hide the encrypted text by Steganographic techniques. İn this project pairs use private key encryption sistems, for this reason pair must share private key over the secure channel. İn this project pairs can share private key over the insecure channel by Steganographi techniques
