Consonance
Consonance implements WhatsApp's handshake process which makes use of Noise Pipes with Curve25519, AES-GCM, and SHA256 from Noise Protocol.
META-INF
consonance version: 0.1.5
released: 2021-12-14
requires:
- python>=2.5,<=3.7

Installation
From source:
python setup.py install
Using Pip:
pip install consonance
Usage
Configuration
Before performing a handshake, you have to define your configuration as a WhatsApp client. This can be done by passing
the configuration parameters to an instance of ClientConfig
. Normally this configuration includes details about
the device WhatsApp is running on. Those device details are to be passed to ClientConfig's useragent
parameters
through an instance of consonance.config.useragent.UserAgentConfig
. In order to facilitate usage,
templates for UserAgentConfig
with some pre-set parameters exist under consonance/config/templates
.
from consonance.config.client import ClientConfig
from consonance.config.templates.useragent_samsung_s9p import SamsungS9PUserAgentConfig
import uuid
client_config = ClientConfig(
username=999999999, # username/phone number
passive=True, # passive connection, you will not send any data after handshake, only receive
useragent=SamsungS9PUserAgentConfig(
app_version="2.19.51", # WhatsApp app version to pose as
phone_id=str(uuid.uuid4()) # uuid that was used to register the aforementioned username
),
pushname="consonance" # display name for push notifications
)
In addition to ClientConfig
one must possess a KeyPair that'll be used in the handshake process and for
authenticating yourself to WhatsApp. This KeyPair was produced and used during registration and therefore the
same one has to be used here for a successful authentication. For testing purposes you could always generate a
fresh KeyPair, in which case the handshake process would go through but authentication fails.
from consonance.structs.keypair import KeyPair
import base64
keypair = KeyPair.generate()
# or keypair used at registration, deserialized from concat. of private_bytes and public_bytes
keypair = KeyPair.from_bytes(
base64.b64decode(b"YJa8Vd9pG0KV2tDYi5V+DMOtSvCEFzRGCzOlGZkvBHzJvBE5C3oC2Fruniw0GBGo7HHgR4TjvjI3C9AihStsVg==")
)
Connect and Authenticate
With your ClientConfig
and KeyPair
you can now attempt a login to WhatsApp. The example below will
demonstrate a XX handshake since
we are not specifying WhatsApp's static public key:
from consonance.protocol import WANoiseProtocol
from consonance.streams.segmented.wa import WASegmentedStream
from consonance.streams.arbitrary.arbitrary_socket import SocketArbitraryStream
import socket
wa_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
wa_socket.connect(("e1.whatsapp.net", 443))
# send WA header indicating protocol version
wa_socket.send(b"WA\x04\x00")
# use WASegmentedStream for sending/receiving in frames
wa_socket_stream = WASegmentedStream(SocketArbitraryStream(wa_socket))
# initialize WANoiseProtocol
wa_noiseprotocol = WANoiseProtocol(4, 0)
# start the protocol, this should perform a XX handshake since
# we are not passing the remote static public key
try:
wa_noiseprotocol.start(wa_socket_stream, client_config, keypair)
print("Handshake completed, checking authentication...")
# we are now in transport phase, first incoming data
# will indicate whether we are authenticated
first_transport_data = wa_noiseprotocol.receive()
assert first_transport_data == 51
except:
print("Handshake failed")
