Abstract

Abstract :In today’s information age, communication play a very  important role which  help in growth of new technologies. So security is an essential parameter to be considered. A mechanism is therefore needed to secure the information that is sent. The process of transforming the original information into an unreadable format is known as encryption.  The  process of  again  converting  the unreadable format  in  to the original  information  is  known  as decryption. The study of both encryption and decryption is known as cryptography. This paper focuses on analyzing different types of cryptography, concept of encryption and decryption, a brief introduction to cryptography techniques. If we are taking about security of information then following  services come in mind i.e. Confidentiality  (privacy  of information), Authentication, Integrity (has not been altered) .This paper provides a detailed description of all these cryptography techniques and a public key cryptography algorithm RSA.
