    What is RSA Algorithm?<\/h3>\n

    RSA is a public key<\/strong> cryptographic algorithm in which two different keys are used to encrypt and decrypt the message. That\u2019s why it is also called an asymmetric<\/strong> key algorithm.<\/p>\n

    But what was the need of this asymmetric key cryptography? Why it evolved? Let us discuss the reason behind the evolution of asymmetric key cryptography. The Asymmetric key cryptography evolves due to the two problems<\/strong> of symmetric key cryptography<\/strong>.<\/p>\n

    The first problem<\/strong> with symmetric key cryptography is the key distribution. The two communicating parties may already be sharing the key which has been distributed to them by any means or the key must be shared with the help of a key distribution centre<\/strong>. But, using of key distribution centre compromises the secrecy of the key which hampers confidentiality<\/strong> of the message.<\/p>\n

    The second problem<\/strong> with symmetric key cryptography is digital signatures<\/strong>. That is, there was a requirement of digital signatures which would assure all the parties that message has been sent from a particular individual. So, there was a lack of authentication<\/strong>.<\/p>\n

    Both of these problems of symmetric key cryptography lead to the evolution of asymmetric key cryptography. In the year 1978 the three inventors at MIT; Rivest, Shamir and Adleman introduced RSA public key algorithm which follows the essential steps below:<\/p>\n
