Python Packet Handler

Store data as packet. Send, Recv, Encrypt and Compress it.

You will be able to manage socket communication easily and comprehensibly using this Python package. With version 1.0.9 or later, you can use the "addListener" function to direct incoming opcodes to the desired function upon receipt.

Please refer to the Example Usage file for details and run it for demonstration.

These packages are also available for C# and C++ programming languages:

C#: https://github.com/emrecpp/DataPacket-CSharp

C++: https://github.com/emrecpp/DataPacket-CPP

Installation

You can install PacketHandler using pip:

pip install PacketHandler

Usage (Detailed Usage)

from Packet import Packet, ref
import sys, socket, select, time

class opcodes:
    LOGIN=100
    LOGOUT=101

HOST, PORT = "127.0.0.1", 2000

CLIENT

Paket = Packet(opcodes.LOGIN, Encrypt=True, Compress=True)
Username = "Emre"
Paket << Username << "123" << True << bytearray(b'\x07\x10BYTES\xFF') << ["Apple", "Banana", "Orange"]
Paket.Send(socket)

SERVER

# Listener Thread
PaketListen = Packet()
while True:
    if PaketListen.Recv(socketServer):
        PaketListen.Print("RECEIVED PACKET (YOUR TITLE)!")
        if PacketListen.GetOpcode() == opcodes.LOGIN:
            UserName, Password, RememberMe, Data, Fruits = ref(str), ref(str), ref(bool), ref(bytearray), ref(list)
            PacketListen >> UserName >> Password >> RememberMe >> Data >> Fruits
            UserName, Password, RememberMe, Data, Fruits = str(UserName), str(Password), RememberMe.obj, bytearray(Data.obj), ", ".join(Fruits.obj)  # We have to cast ref object to (int, str, bool, bytearray ...)
            # Note: Can't use bool(RememberMe), this returns True everytime. Use .obj always !!!

            print(f"Username: {UserName}\nPassword: {Password}\nRememberMe: {'Yes' if RememberMe else 'No'}\nData: {str(Data)}\nFruits: {Fruits}")
    else:
        return # Connection Lost

OUTPUT

Username: Emre
Password: 123
RememberMe: Yes
Data: bytearray(b'\x07\x10BYTES\xff')
Fruits: Apple, Banana, Orange
