This paper will present a perspective on the current state of play in the field of encryption algorithms, in particular on private key block ciphers which are widely used for bulk data and link encryption. The authors have initially survey some of the more popular and interesting algorithms currently in use. This paper focuses mainly on the different kinds of encryption techniques that are existing, and comparative study all the techniques together as a literature survey. Aim an extensive experimental study of implementations of various available encryption techniques. Also focuses on image encryption techniques, information encryption techniques.
