Achieving security is the major task considered while sending messages over the network. The science of sending encoded messages or data is known as cryptography. By using cryptography, the authors can make the message unreadable and thus providing security, privacy and reliability to the confidential data. A system using this technique is called as cryptographic system or cryptosystem which are the only way which allows the user to access the encrypted data and decrypt it for making the data readable. The authorized users can share the authenticated messages with each other.
