Readme

SocksLib

Sockslib is a library designed to make the usage of socks proxies as easy as possible. This library can connect to proxies, authenticate, and then have the use of a normal python socket.

Downloads PyPI version fury.io

  • IPv4 Support
  • IPv6 Support (Socks5)
  • Domain Support
  • User/Pass authentication (Socks5)
  • Easily customizable authentication (Socks5)

Intro

Creating a new socket
socket = sockslib.SocksSocket()
Setting a proxy
socket.set_proxy (
	('127.0.0.1', 0),      # Ip, Port
	sockslib.Socks.SOCKS5, # SOCKS5/SOCKS4, (Optional) (Default SOCKS5)
	authentication         # Array of authentication methods (Optional) (Default NoAuth)
)
Set a default proxy

Default proxies can be useful for situations when other libraries use sockets to communicate and you want to force that library to use a proxy instead of a direct connection

sockslib.set_default_proxy(
	('127.0.0.1', 0),      # Ip, Port
	sockslib.Socks.SOCKS5, # SOCKS5/SOCKS4, (Optional) (Default SOCKS5)
	socket.AF_INET,        # Default protocol (AF_INET, AF_INET6)
	authentication         # Array of authentication methods (Optional) (Default NoAuth)
)
URLLib Proxied
import urllib.request

import sockslib
import socket

sockslib.set_default_proxy(('127.0.0.1', 9050)) # Set the default proxy
socket.socket = sockslib.SocksSocket # Make the default socket object a SocksSocket

html = urllib.request.urlopen('https://myexternalip.com/raw').read() # Request the page
print(html)

IPv6

To connect to a proxy server via ipv6, you must explicitly specify the protocol by passing the ip_protocol parameter to the SocksSocket constructor, OR by using the 3rd option of set_default_proxy. Here is an example of connecting to a remote IPv6 proxy:

import sockslib
import socket # import socket for the protocol specifiers 

with sockslib.SocksSocket(ip_protocol=socket.AF_INET6) as sock:
    sock.set_proxy(('::1', 9050)) # Set proxy

    sock.connect(('myexternalip.com', 80)) # Connect to Server via proxy 
    sock.sendall(b"GET /raw HTTP/1.1\r\nHost: myexternalip.com\r\n\r\n") # Send HTTP Request
    print(sock.recv(1024)) # Print response

Examples

SOCKS5

Socks5 TCP

This is an example usage that connects to a Socks5 proxy at 127.0.0.1:9050 and then requests the page http://myexternalip.com/raw

import sockslib

with sockslib.SocksSocket() as sock:
    sock.set_proxy(('127.0.0.1', 9050)) # Set proxy

    sock.connect(('myexternalip.com', 80)) # Connect to Server via proxy
    sock.sendall(b"GET /raw HTTP/1.1\r\nHost: myexternalip.com\r\n\r\n") # Send HTTP Request
    print(sock.recv(1024)) # Print response

Socks5 UDP

This is an example usage that connects to a Socks5 proxy at 127.0.0.1:9050 and then sends a UDP packet.

import sockslib

with sockslib.SocksSocket(udp=True) as sock:
    sock.set_proxy(('127.0.0.1', 9050)) # Set proxy

    sock.initudp() # Connect to Server and bind a UDP port for communication
    sock.sendto(b"Hello, World", ("0.0.0.0", 12000)) # Send "Hello, World" to 0.0.0.0:12000 over UDP

Due to the nature of UDP in the SOCKS5 protocol, it is reccomended to use the context manager, as the remote proxy server will not drop the UDP associate request until the socket is closed.

Using other authentication methods

To use more authentication methods like User/Pass auth, you pass an array of authentication methods to the third parameter of set_proxy (Don't neglect to set the second parameter to the proxy type!)

import sockslib

with sockslib.SocksSocket() as sock:
    auth_methods = [
        sockslib.NoAuth(),                             # No authentication
        sockslib.UserPassAuth('username', 'password'), # Username / Password authentication
    ]
    sock.set_proxy(('127.0.0.1', 9050), sockslib.Socks.SOCKS5, auth_methods) # Set proxy

    sock.connect(('myexternalip.com', 80)) # Connect to Server via proxy
    sock.sendall(b"GET /raw HTTP/1.1\r\nHost: myexternalip.com\r\n\r\n") # Send HTTP Request
    print(sock.recv(1024)) # Print response

Implementing your own authentication methods

To implement your own socks5 authentication method, you must make a class that implements sockslib.AuthenticationMethod it requires that you implement a getId() function, an authenticate(socket) function, and a forP function. Note: the authenticate function must return a boolean, True if authentication succeeded and False if it failed.

from sockslib.socks import AuthenticationMethod
from sockslib.socks import Socks
import struct

class UserPassAuth(AuthenticationMethod):
    def __init__(self, username, password):
        self.username = username
        self.password = password

    def getId(self):
        return 0x02 # 0x02 means password authentication, see https://en.wikipedia.org/wiki/SOCKS#SOCKS5 for more

    def forP(self):
        return Socks.SOCKS5 # For SOCKS5

    def authenticate(self, socket):
        socket.sendall(b"\x01" + struct.pack("B", len(self.username)) + self.username.encode() + struct.pack("B", len(self.password)) + self.password.encode()) # Send authentication packet
        ver, status = socket.recv(2) # Get authentication response

        return status == 0x00

Socks4

This is an example usage that connects to a Socks4 proxy at 127.0.0.1:9050 and then requests the page http://myexternalip.com/raw

import sockslib

with sockslib.SocksSocket() as sock:
    sock.set_proxy(('127.0.0.1', 9050), sockslib.Socks.SOCKS4) # Set proxy

    sock.connect(('myexternalip.com', 80)) # Connect to Server via proxy
    sock.sendall(b"GET /raw HTTP/1.1\r\nHost: myexternalip.com\r\n\r\n") # Send HTTP Request
    print(sock.recv(1024)) # Print response
Socks4 with identity authentication
import sockslib

with sockslib.SocksSocket() as sock:
    auth_methods = [
        sockslib.Socks4Ident("ident")
    ]
    sock.set_proxy(('127.0.0.1', 9050), sockslib.Socks.SOCKS4, auth_methods) # Set proxy

    sock.connect(('myexternalip.com', 80)) # Connect to Server via proxy
    sock.sendall(b"GET /raw HTTP/1.1\r\nHost: myexternalip.com\r\n\r\n") # Send HTTP Request
    print(sock.recv(1024)) # Print response
