You clearly explained how symmetric cryptography works and why it’s efficient for bulk encryption. I liked the fact that you underlined its speed advantage and how it provides confidentiality. One thing to note is that the reliance on key exchange may render it somewhat vulnerable, which is where asymmetric cryptography adds value through secure key distribution and authentication support, even though it’s much slower. Hybrid systems use both to achieve a balance in speed and security.
