Login Sequence:

0. Packet format:

First comes a VarInt of the packet's length (in bytes). Then there is the 1 byte packet ID, and finally the payload.

1. Handshake packet:

First of all, a handshake packet must be sent:

Field	Example	Field Type	Length
Packet ID	0x00	Byte	1 byte
Protocol Version	47	VarInt	Depends
Server Address	localhost	String	Depends
Server Port	25565	Unsigned Short	2 bytes
Next State	1	VarInt	Depends

The "Next State" field comes in two forms: 1 is for status ping, 2 is for login.
