RSA (Rivest-Shamir-Adleman) Algorithm | Gaurav Parmar

RSA (Rivest-Shamir-Adleman) Algorithm :
RSA can be treated like an authentication system and internet encryption that uses algorithm. It was developed by Ron Rivest, Adi Shamir and Leonard Adleman in 1977 and was named after them. It is an algorithm for public key cryptography. Anyone can use the public key to encrypt a message but with recently published methods if public key is large then after having the knowledge of prime factors only one can decode the message. It involves a public key and a private key. The public key is known to everyone and is used for encrypting messages while messages encrypted with public key can only be decrypted in a reasonable time span with private key. Before any communication starts, the server calculates its public and private key and to initiate a transaction, the web browser sends its message to the server requesting its public key and then using that public key it encrypts the message to be sent and sends it to the server and server receives the encrypted message and by using the public and private key decrypts it back.

  2. I recently became familiar about this algorithm. I read several other posts to learn about it but the above info is unique and interesting. Thank you for discussing about it.
