More of your questions answered by our Experts. The following code example initializes an RSACryptoServiceProvider object to the value of a public key (sent by another party), generates a session key using the Aes algorithm, and then encrypts the session key using the RSACryptoServiceProvider object. RSA encryption is a public-key encryption technology developed by RSA Data Security. Public key encryption is a method of encrypting data with two different keys — a public key that is available to everyone and a private one that is known only to the recipient. RSA_public_encrypt() returns the size of the encrypted data (i.e., RSA_size(rsa)). Cryptocurrency: Our World's Future Economy?
