AES	Advanced Encryption Standard
	Symmetric encryption algorithm that is widely used in IPsec for data encryption. It comes in different key sizes (e.g., AES-128, AES-256).
CBC	Cipher Block Chaining
	CBC does not have this "authentication" capability

GCM	Galois/Counter Mode
	AES-GCM is an authenticated encryption algorithm designed to provide both authentication and privacy.
