Title: Writing program in C++ or Java to implement RSA algorithm for key generation and cipher verification. Objective: To study‚ 1. Public key algorithm. 2. RSA algorithm 3. Concept of Public key and Private Key. Theory: Public Key Algorithm: Asymmetric algorithms rely on one key for encryption and a different but related key for decryption. These algorithms have the following important characteristics: • It is computationally

derived from the Greek words kryptos meaning “hidden” and graphien‚ meaning “to write/study”. The process of making and using codes to secure the transmission of information is called cryptography. Before modern era cryptography was synonymous to encryption but today cryptography is heavily based on mathematical theory and computer science practice. Cryptography today deals with the ways to transfer information in such a manner that no one beside the recipients can read what was actually sent and also

as evidence in a court or law These facilities are delivered using a mathematical technique called public key cryptography‚ which uses a pair of related cryptographic keys to verify the identity of the sender (signing) and/or to ensure privacy (encryption). How the Public Key Cryptography concept works Public key cryptography uses a pair of mathematically related cryptographic keys. If one key is used to encrypt information‚ then only the related key can decrypt that information. Even if one
