Handshake Success Packet

Handshake Success Diagram

📦 Size​

33 bytes

  • TYPE: 8 bits
  • XTEA256 SESSION KEY: 256 bits (32 bytes)

📤 Sent By​

Server, after successfully verifying the client's handshake response.

🧪 Contents​

  • A newly generated 256-bit session key, used for all future communication
  • The TYPE field (0x04) is unencrypted
  • The session key itself is encrypted using the static shared key

🔒 Purpose​

This packet finalizes the handshake process by securely sharing
a newly generated 256-bit session key with the client.

Once the client decrypts this key using the shared handshake key,
both sides switch to session-level encryption for all subsequent communication.

No plaintext content will be transferred after this point.
