# 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: 0.1.3 released: 2019-05-22 requires: - python>=2.5,<=3.7 - dissononce >= 0.34.3 - transitions - protobuf >= 3.6.0 - python-axolotl-curve25519 ``` ## 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```. ```python 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. ```python 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](https://noiseprotocol.org/noise.html#interactive-handshake-patterns-fundamental) handshake since we are not specifying WhatsApp's static public key: ```python 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\x02\x01") # use WASegmentedStream for sending/receiving in frames wa_socket_stream = WASegmentedStream(SocketArbitraryStream(wa_socket)) # initialize WANoiseProtocol 2.1 wa_noiseprotocol = WANoiseProtocol(2, 1) # start the protocol, this should perform a XX handshake since # we are not passing the remote static public key if 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 == 172 ``` - See [examples/walogin_handshake_xx.py](examples/walogin_handshake_xx.py) for the full ```XX``` handshake example. - See [examples/walogin_handshake_ik.py](examples/walogin_handshake_ik.py) for a ```IK``` handshake example. - See [examples/walogin_handshake_xxfallback.py](examples/walogin_handshake_xxfallback.py) for a ```XXfallback``` handshake example. - See [Interactive handshake patterns](https://noiseprotocol.org/noise.html#interactive-handshake-patterns-fundamental) and [Noise Pipes](https://noiseprotocol.org/noise.html#noise-pipes) from Noise for information about the handshake types used here.
