With RSA, of course, one key is clearly the private key ...PGP is an early and well-known hybrid system. The receiver's public key encrypts a symmetric algorithm key which is used to encrypt the main message. This combines the virtues of both algorithm types when properly done. We discuss asymmetric ciphers in much more detail later in the Public Key Overview and following sections of this book.Description. RSA is an asymmetric encryption algorithm. With a given key pair, data that is encrypted with one key can only be decrypted by the other. This is useful for encrypting data between a large number of parties; only one key pair per person need exist. RSA is widely used across the internet with HTTPS.Speed: symmetric key encryption is very fast but asymmetric encryption is complex and slower. Security: in symmetric key encryption the key has to be shared with all the participants which decreases the security whereas the public key is shared only with the message senders which is more secure.
