FUNDAMENTAL OF CRYPTOGRAPHY UP TO RSA

Today, in the digital world protecting the data plays a basic role in exchanging the messages and business exchanges. Encryption is used to supply the security needs of a safe transaction. Given the importance of this subject and passing from a traditional stage to a digital one, familiarity with encryption methods seem to be necessary. Here, in addition to studying the encryption algorithms for asymmetric and symmetric keys, various aspects of asymmetric key will be studied and characteristics of each one will be described.
