== Introduction ==
|
|
|
|
The RuneScape Protocol is the language in which the RuneScape client and
|
|
server communicate. The protocol changes for every version.
|
|
|
|
The entire protocol is generally separated into two different
|
|
categories:
|
|
|
|
- Login Protocol
|
|
- Game Protocol
|
|
|
|
== Login Protocol ==
|
|
|
|
The Login Protocol is the protocol that is used to log a player into
|
|
RuneScape. This protocol contains information that sets up the
|
|
encryption for the entire session, using the ISAAC algorithm. The "login
|
|
block" is encrypted using RSA to prevent third party programs from
|
|
packet-sniffing the ISAAC cipher keys and breaking the session
|
|
encryption for the purpose of monitoring, injecting, and generally
|
|
sniffing packets.
|
|
|
|
== Game Protocol ==
|
|
|
|
The Game Protocol is the protocol in which game action information is
|
|
transmitted. The opcodes are encrypted using ISAAC in order to prevent
|
|
third party programs from tampering with the stream. The game protocol
|
|
is made up of packets that are structured like so:
|
|
|
|
<pre>
|
|
For fixed-size packets:
|
|
opcode, payload[size]
|
|
|
|
For variable-sized packets:
|
|
opcode, size, payload[size]
|
|
</pre>
|
|
The ''opcode'' of a game packet is basically an identifier for the type
|
|
of game action that the packet represents. The ''size'' of the packet is
|
|
the amount of bytes that the payload of the packet carries, and the
|
|
''payload'' is an array of bytes that holds the actual data
|
|
(information) of the packet.
|
|
|
|
A ''fixed-size'' packet is a packet whose payload size does never
|
|
change, and the size for the specified opcode is already known between
|
|
both client and server. A ''variable-sized'' packet is a packet whose
|
|
payload size changes according to the situation of the game session.
