Case Study: Asymmetric Cryptography in HTTPS
When you visit a secure website (HTTPS), asymmetric cryptography ensures the security of your communication:
- The server provides its public key in the form of a digital certificate.
- Your browser uses this public key to encrypt a session key (used for symmetric encryption).
- The server decrypts the session key with its private key.
- Subsequent communication between your browser and the server is encrypted using symmetric encryption for efficiency.
This process guarantees secure, private communication, protecting sensitive data like passwords and credit card information.
