whatsapp-web-reveng's Issues

send Message

I'm trying to implement the messaging part, but my knowledge regarding this type of project is very small, do you have alpha idea of how does the way data encryption work? after encrypted just send via websoket send? Do you have any idea of the structure of sending the message?

README mentions AES-ECB, code uses AES-CBC

I'll just assume the code is right. I was a bit surprised to see ECB mentioned there as that alone would allow a few nefarious attacks on the ciphertext.

Reusing the login credentials

Hey

After getting annoyed of always having to scan the QR code I tried myself implementing the authentication after the initial one.

Sadly I was unable to do so. I am currently sending the exact same message as the web client does.

message = messageTag + ',["admin","login","' + clientToken + '","' + serverToken + '","' + self.loginInfo["clientId"] + '",takeover]';
self.activeWs.send(message);

Is there a way to contact you @sigalor ? Would like to work together.

ERR_CONNECTION_REFUSED

Good afternoon!

I made the installation on a ubuntu 16.04 LTS server and when I click connect the following ERR_CONNECTION_REFUSED error appears:
Has anyone gone through this?
Thank you.

Invalid

wtf, how did I create this issue

Possible double WATags

The value of BINARY_32 and PACKED_MAX in whatsapp_defines.py is both 254. I'm not sure if it's supposed to be like that but I figured someone who actually knows what this means should probably judge that.

License is ambiguous

Hi,

Just need a clarification here: your "Terms and Conditions" section can be interpreted to be part of the software's license, but the repository contains a LICENSE file without these terms. So:

Are the terms in "Terms and Conditions" additional software license terms on top of the MIT License; or
Are the terms in "Terms and Conditions" just a disclaimer against supporting users who use the software for those purposes?

Note that the first option makes this software non-free and possibly GPL-incompatible, which could cause some interoperability problems.

How can I find my contact is online?

On whatsapp web I can find any person is online with below code.

Store.Precense.find("[email protected]").then(function (d) { console.log(d.isOnline) })

but since few days it's not returning correct data until I open that contact's chat screen on my android.
Can I do then same thing with this or there is an other way?

Trying to follow E2E media decryption documentation

I'm trying to follow Dealing with E2E media documentation, recently incorporated in pull request 42 by @valga and @sigalor

My implementation is on NodeJs but I believe I'm following everything step by step. However the decoded file is too small and cannot be opened. This a sample file you can run directly, documented step by step:

// How to install dependencies and run this index.js file:
// npm init
// npm install hkdf
// npm install atob
// npm install btoa
// node index.js

const crypto = require('crypto');
const HKDF = require('hkdf');
const atob = require('atob');
const btoa = require('btoa');

And this is the output:

decodedHex: b0005ed320ac3fffd9 (9 bytes)

The output (decodedHex) is wrong, it should be a much bigger 313 byte file. Any hint on what I'm doing wrong? I don't know the value of AES.block_size but I'm using "aes-256-cbc" as per link and because the key length is wrong for 128.

It would be great if someone could try to reproduce this in Python with the same input data provided and be able to generate the output small .jpeg file.

How can I send msg to a contact ?

Hey,
First, congrats it looks great!!!

One question, how can I send a message to a specific contact?

Regards,

can't connect: message type: closed

Hi,
I've been using this project for a while without problems but since the last 2 days I've not been able to connect.
I get every time the following message on Chrome console while trying to connect to he API:
got message {from: "meta", type: "closed"}

Above I get the following message:
WebSocket connection to 'ws://localhost:2019/' failed: Connection closed before receiving a handshake response

This happens every time I click on the Click to connect to API button.

Backend, API server and HTTP server seems to be running fine.

Parameters for the "login" command

Have you already tried to figure out what parameters are used for the "login" command? Here is a screenshot from Chrome DevTools:

This command is sent by the WhatsApp web application when an already authenticated client reopens a web socket connection (for example after page reloading or browser reopening).

Hint: I noticed that after sending a "login" command, a server "Conn" response no longer contains a "secret" along with other parameters. It confirms that the server implies that the client is already authenticated and has all required credentials (which is a perfectly valid assumption).

Inaccuracy

Messages history

Tell me please. How can I get a message history with a contact? Thank you!

Does it require my WhatsApp on Phone to be always online?

I wanted to know how this is different from Whatsapp Web and what is the significance of it in terms of extended capabilities?

how to get image and send message

Hello sigalor,
i started my panel and login successfully .
but how can find my image and send message. please guide me
thank Manoj Rao

Inaccuracy in the step #12 description

Hi, and thanks for this titanic work!
It seems there is some inaccuracy in the description of the step #12:

Encode a message containing 32 null bytes with the shared secret using HMAC SHA256. Take this value and extend it to 80 bytes using HKDF. Call this value sharedSecretExpanded. This is done with HKDF(HmacSha256("\0"*32, sharedSecret), 80).

According to the code 32 null bytes here is used as a key and not as a message.
I'm implementing the described algorithm for iOS and still cannot pass the HMAC validation, just trying to find where I could be wrong.

add subscribe

@sigalor
for subscribe iv add to
backend
whatapp-web-backend.py
with
elif cmd == "backend-subscribe": currWhatsAppInstance.subscribe(callback); self.sendJSON({ "type": "resource_subscribe", "resource": "whatsapp", "resource_instance_id": obj["whatsapp_instance_id"] }, tag);

and
add to

whatsapp.py

def subscribe(self): messageTag = str(getTimestamp()); self.activeWs.send(messageTag+',["action","presence","subscribe","number"]');

it's work greet it's subscribe but how can I edit it get parameter number like
def subscribe(number)

Can I initiate a new chat with a number not yet saved to my contacts?

I need to send messages to numbers I have not yet saved to my contacts through WhatsApp. WhatsApp officially said that they provide an API, click to chat, that responds to an open-xdg native application, chats to a new number and creates a new room for that.
Is it possible to create a new chat with a new number without opening the native app or staying on the website of whatsapp-web_reveng? Alternatively, does an API exist to do this in a humanly way?

Hey guys anyone discovered how to get the pushname of a jid?

The pushname is the name the user configure after he creates his account in the app.

I tried to check on WA WEB but i couldn't find anything.

How do you keep WA online?

Hi,
Simple question how do you keep your WA account/s online? I mean WA app must be always online to be able to access WA web?

Message sending flow

Hi there,

we are trying to send messages over the websocket connection, but WhatsApp always responds with a 401 stastus code. Our message object looks like this:

[
    "action",
    {
        "type": "relay",
        "epoch": "17"
    },
    [
        [
            "message",
            null,
            {
                "key": {
                    "remoteJid": "[email protected]",
                    "fromMe": true,
                    "id": "01234567890ABCDEF0123"
                },
                "message": {
                    "conversation": "Your message"
                },
                "messageTimestamp": 1526455013,
                "status": 1
            }
        ]
    ]
]

Our workflow looks like this:

marshal the inner object with protobuf
parse the node to the binary format
encrypt the binary with cbc and the encKey
take the id and put it into the output message as the messageTag followed by a ','
hash the cipher with hmac and append the first 32 bytes to the output message
append the cipher to the output message
send the message

We implemented our own parser in golang and just wanted to check if you have more information on message sending. Our parser seems to be working, at least we can parse messages back and forth between the binary format and json with protobuf inside

If you set a breakpoint in the app.js in line 43808 you can check out the messages sent through WhatsAppWeb (see e.binaryOpts.debugObj.pb / xml for the data and e.serialize() for the ArrayBuffer).
We are unable to determine how the id is generated and don´t know if it´s relevant for the message we are sending.
We also don´t know if epoch is relevant, but it seems to be incremental.

Reconnection problem

Hi guys, i'm storing the conn and login infos using pickle:

`
with open('conninfo', 'wb') as handle:
pickle.dump(self.connInfo, handle, protocol=pickle.HIGHEST_PROTOCOL)

    with open('logininfo', 'wb') as handle:
        pickle.dump(self.loginInfo, handle, protocol=pickle.HIGHEST_PROTOCOL) `

I restore those variables and then i can reconnect sucessfully, but only once! in the third try i receive a challenge message:

message:s1,["Cmd",{"type":"challenge","challenge":"wmpflh6NMtwbbjHgQ0iVpI9LNchZlIAwiOVauqmkGb4="}]

I tried to simulate that in the web client but no success, i didn't find any way to receive this challenge in the client.

Any ideias @sigalor ?

get MediaKey

I saw that we return from this amazing project when I get a file it returns me to mediaKey, I would like to know if this return is done by whatsapp server or has some way of generating it based on media_enc_hash and media_enc.

Can I find the keys in the whatsapp web client local storage?

Hi Guys,

reading the readme of this project made me wonder. The text says:

The keysDecrypted variable is 64 bytes long and contains two keys, each 32 bytes long. The encKey is used for decrypting binary messages sent to you by the WhatsApp Web server or encrypting binary messages you send to the server. The macKey is needed to validate the messages sent to you:  
encKey: keysDecrypted[:32]
macKey: keysDecrypted[32:64]

When I use the official web client, would these be keys that are stored in my browsers local storrage? there is a variable there called WASecretBundle...

And... I read:

AESDecrypt(encKey, messageContent[32:])

Which AESDecrypt function is this? I can't seem to find the source of a AESDecrypt function.. and, doesn't this need a IV parameter (initialization vector)?

window.Store.Wap was depracated ? (web api)

WhatsApp APK not working after recompilation

This issue came from #45.
I have recompiled the WhatsApp APK without changing its source code, but it's not working after the recompilation process, because they are validating their APK signature.
I have also tried the same with GBWhatAapp; here, I don't get any errors and generally, it's working fine, but there is an issue with the network connection.
So I asked how to bypass this signature validation and @sigalor commented as he has already recompiled the WhatsApp APK and it's working fine. I'd appreciate if he would share how he did it.

EDIT: I have enabled logs for WhatsApp APK and I'm getting a bad-token error when I try to do registration or request-sms.

[question] end-to-end encryption in whatsapp web? push notifications?

Hi, short question regarding encryption: Is WhatsApp-Web properly end-to-end encrypted? If i understood right, the phone needs to be online at all times in order to encrypt messages. So the chain of communication works like this(?): 1. Sending message via Whatsapp Web --> 2. message sent to WhatsApp server (websocket) -->3. server forwards message to phone --> phone encrypts message and sends it out to the server again?
Did I understand that right? Is the communication from step 1 - 3 readable by WhatsApp?
Also: In WhatsApp-Web, you can enable push notifications. In order for them to work, the messages need to be routed through a chrome/mozilla push-service. Does that mean that Google/Mozilla can read all the messages?
Thanks in advance!

Any ideia on how to send messages?

Hey man, great work! It's working perfectly!

Do you have any plans on adding a way to send messages in this project?

Document that the binary message comes with a tag that should be discarted

First, thanks a lot by this extensive documentation

In this section of the documentation:

Validating and decrypting messages
Now that you have the two keys, validating and decrypting messages the server sent to you is quite easy. Note that this is only needed for binary messages, all JSON you receive stays plain. The binary messages always have 32 bytes at the beginning that specify the HMAC checksum.

Took me a while to realize that the binary message comes with a tag that should be discarted.
I had to look in the implementation to understand that. I guess that this section could describe this too.

Can't run on Windows 10

It took quite some time to get all the depencies, but I managed to do it, and this is what happens when I try to run the project. ~~(Sorry for the poor formatting)~~ fixed thanks to @SuperSandro2000!

I guess it seems like a Windows issue?

Which version of windows works

Hello

First of all, excellent project friend, I have been using yowsup for some time and I found out that your project existed and I want to try it.

My question is, what version of Windows works? I have Windows 10 and the truth is giving me many errors, I have installed the Node 8, python 2.7.15 64 bits.

The error that most presents is:

gcc exited with status 1

Thank you.

Issues sending a message

Hi there, thanks for doing all the hard work finding this out and putting it all in this repo!

I'm having an issue sending a message and am unable to find out what I'm doing wrong.

I used this: #63 (comment) and the golang library from @Rhymen as a reference (https://github.com/Rhymen/go-whatsapp).

The serialization I'm using is the whatsapp_binary_writer.py included in this project.

These are the steps I'm taking:

Create a new WebMessageInfo proto object with the following fields set:
- key.fromMe = true
- key.remoteJid = remoteJid
- key.id = 10 byte hex code (I've also tried 32 bytes)
- messageTimestamp = unix time now
- status = 1
- message.conversation = content of message
Serialize this WebMessageInfo
Create the object ["action", { "type": "relay", "epoch": "1" }, [ [ "message", None, <serializedWebMessageInfo> ] ]] and pass it through whatsappWriteBinary
create a tag with getTimeStamp
create a HMAC SHA265 hash of the object created with the macKey
AES encrypt the object created with the encKey
send the following message: <tag>,<0x16><0x00><hashed><encrypted>

I don't get any response from WA, so it's hard for me to find out what exactly goes wrong. @Rhymen or @sigalor have you encountered this? And if so; could you help me in the right direction?

Thanks so much!
