Quizplus · Accepted Answer

PGP (Pretty Good Privacy) is a hybrid cryptosystem that combines symmetric-key encryption and public-key cryptography. It is widely used for secure e-mail communication and file storage applications, and is considered the open-source de facto standard for encryption and authentication. DES and AES are symmetric-key encryption algorithms, while AH and ESP are protocols used for IPsec (Internet Protocol Security).
