WebMay 20, 2024 · RSA is a public key or asymmetric key algorithm. RSA stands for Rivest, Shamir and Adleman the three inventors of RSA algorithm. Each user has to generate two keys public key known to all and private key only known to him. Encryption is done using the public key of the intended receiver. A receiver cracks the message using its private key.
