WebJun 28, 2024 · At the highest level, this is how PGP encryption works: First, PGP generates a random session key using one of two (main) algorithms. This key is a huge number that cannot be guessed, and is only used once. Next, this session key is encrypted. This is done using the public key of the intended recipient of the message. WebSymmetric ciphers protect data privacy in most Wi-Fi networks, online banking and e-commerce services, and mobile telephony. Some protocols use asymmetric cryptography to encrypt and authenticate endpoints. They also use it to secure the exchange of symmetric keys to encrypt session data.
