: Since RSA is computationally expensive, it is often used to securely exchange a symmetric key , which then handles the bulk encryption of larger data sets. How the RSA Algorithm Works Key Generation : Select two large, distinct prime numbers ( ) and calculate their product ( ), which serves as the modulus for both keys. Public Key Creation : An integer
According to experts from TechTarget and RSA Security , RSA is primarily used for: RSA and Public Key Cryptography Cryptography
: Verifying the authenticity and integrity of messages or software by "signing" them with a private key. : Since RSA is computationally expensive, it is
: RSA is unique because either key can be used for encryption with the other performing the decryption, which allows it to be used for both confidentiality and authentication. : RSA is unique because either key can
(encryption exponent) is chosen such that it is relatively prime to . The public key is the pair : A private exponent
