Detailed Description

Crypto parameters packet structure (Packet Type 15)

Sent by server to client during crypto handshake to communicate chosen algorithms and algorithm-specific data sizes for handshake.

Note: This packet must be sent UNENCRYPTED (handshake packet).; Structure is 24 bytes total (packed).
