Episode notes
Asymmetric Encryption's Role
- Most web traffic uses symmetric encryption, requiring a shared secret.
- Asymmetric encryption solves the key exchange problem for symmetric encryption.
Asymmetric Encryption Mechanics
- Asymmetric encryption involves separate private and public keys.
- The public key encrypts messages, while only the private key decrypts them.
Ephemeral Key Exchange
- Attackers need to intercept the initial communication to compromise the encryption.
- Ephemeral Diffie-Hellman key exchange makes this more difficult.
