PGP (Pretty Good Privacy) is a public key encryption system that authenticates the sender and encrypts the email data during transmission. It is widely used for secure communications and is compatible with various email clients. SSH (Secure Shell) is a protocol used for secure remote login to a server, IPSec (Internet Protocol Security) is a protocol suite for securing Internet Protocol (IP) communications, and SSL (Secure Sockets Layer) is a protocol used to create a secure connection between a web server and a web browser. However, none of these options specifically address email encryption and sender verification like PGP does.
