Data Transfer Protocol for Python
Cross-platform networking interfaces for Python.
Data Transfer Protocol
The Data Transfer Protocol (DTP) is a larger project to make ergonomic network programming available in any language. See the full project here.
Installation
Install the package:
$ python -m pip install dtppyCreating a server
A server can be built using the Server implementation:
from dtppy import Server
# Called when data is received from a client
def receive(client_id, data):
# Send back the length of the string
s.send(len(data), client_id)
# Called when a client connects
def connect(client_id):
print(f"Client with ID {client_id} connected")
# Called when a client disconnects
def disconnect(client_id):
print(f"Client with ID {client_id} disconnected")
# Create a server that receives strings and returns the length of each string
s = Server(on_receive=receive, on_connect=connect, on_disconnect=disconnect)
s.start("127.0.0.1", 29275)Creating a client
A client can be built using the Client implementation:
from dtppy import Client
message = "Hello, server!"
# Called when data is received from the server
def receive(data):
# Validate the response
print(f"Received response from server: {data}")
assert data == len(message)
# Called when the client is disconnected from the server
def disconnected():
print("Unexpectedly disconnected from server")
# Create a client that sends a message to the server and receives the length of the message
c = Client(on_receive=receive, on_disconnected=disconnected)
# Send the message to the server
c.send(message)Security
Information security comes included. Every message sent over a network interface is encrypted with AES-256. Key exchanges are performed using a 512-bit RSA key-pair.
