The purpose of this project is to design and implementation of DES and RSA algorithm. A computer network is designed to send information from one point to another point. This application will help us to encrypt the data and send to other in secure manner. we have discussed about the DES and RSA and then implement in standard level. The schemes and techniques that we can use to transmit data in encrypted format. In other side the receiver decrypt the data to make readable for human. We would like to express greatest thanks to almighty ALLAH for giving the strength to undertake this project. We would also like to thanks our family for its support and prayers throughout the four years. We also wish to thanks our adviser Sir Faisal Riaz with whom we collaborated on several occasions during BSIT. He was key in exposing and pushing us to areas of cryptographic research covered in this thesis.
