Abstract

With the development of the digital devices, computers and networks, our world relies more and more on the digital data. In many cases, storing data safely is a very big concern. These data have to be protected so as to prevent the possible unauthorized access. Many technologies have been used to improve the security of the data storage. Encryption is a process of coding information which could either be a file or mail message in into cipher text a form unreadable without a decoding key in order to prevent anyone except the intended recipient from reading that data. Decryption is the exactly opposite process of converting encoded data to its original un-encoded form which is nothing but plaintext. Here we are introducing some encryption algorithms.
