WebPGP follows a three-step process: Step 1: PGP generates a huge, one-time-use public encryption algorithm that cannot be guessed, which becomes the random session key. Step 2: The session key is then encrypted using the recipient’s public key, which protects the message while being transmitted. WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an …
