Guys,What should i do?

[finch7]

how can i get client static keypair?
please give me some help

I don't think you can. It's probably encrypted in your app data folder somewhere or in the db...

[Sigma-One]

With iOS I'm not aware of a way, but if you have a rooted Android device available, you can pull the values and axolotl.db from there.

I can't remember the exact location though, you'll have to find that yourself.

Are you sure the client key is in there? I looked through the axolotl.db from my phone but it doesn't appear like there is anything that resembles the client static key...
(btw it's in data/com.whatsapp/databases together with the msgstore.db and other stuff)

I'm gonna guess that you opened that file as the SQLite3 (Android variant) it is, and not as a text or binary file.

Of course. But the only table in the db that looked somehow interesting to me were the prekeys that yowsup also downloads right after registration.

I just checked, apparently I found client_static_keypair and server_static_public in data/com.whatsapp/shared_prefs/keystore.xml

nice I somehow missed that.
I'll try to copy the preshared keys from the app axolot.db into yowsup's db and put in the correct app version,hash etc. See if I can login with yowsup that way...

@Neolysion If you manage to do it correctly can you make a short how-to for dummies?
Basically I already opened the keystore.xml previously and saw the values, however it is a bit unclear as to how to populate the yowsup config (where?) so that I can actually start and try including it in the spectrum2 config...

[bryanjhv]

~/.config/yowsup/[phone]/config.json reads:

{
  "__version__": 1,
  "cc": "[countrycode]",
  "client_static_keypair": "...",
  "edge_routing_info": "...",
  "expid": "...",
  "fdid": "...",
  "id": "...",
  "mcc": "[mcc]",
  "mnc": "[mnc]",
  "phone": "[phone]",
  "pushname": "[yourname]",
  "server_static_public": "...",
  "sim_mcc": "000",
  "sim_mnc": "000"
}

Alternative, keyval format:

Where is that saved?
https://github.com/tgalal/yowsup/blob/f14a03fb780410ab949bc76855b2039e65866b7d/yowsup/common/tools.py#L85-L108

I'd love people reading code and/or learning at least Python before asking.

Hi guys, sorry for reopening the topic, but I've got the keyspair from this file data/com.whatsapp/shared_prefs/keystore.xml and I tried to use convert it to BASE64 but the code complained about the length. Is there something I'm doing wrong here?

[baptx]

@bryanjhv I got the same error as @samy-mohsen: ValueError: Wrong length: 86 with the command to send a message yowsup-cli demos -s CCYYYYYYYYY hello --config-phone CCXXXXXXXXX where CC is the country code, X are my phone number digits (without the unnecessary first digit "0") and Y are the phone number digits of someone else.
I tried with the JSON format in ~/.config/yowsup/CCXXXXXXXXX/config.json and the keyval format in ~/.config/yowsup/CCXXXXXXXXX/config.yo.
I converted the client_static_keypair found in the file shared_prefs/keystore.xml of the official Android WhatsApp client with the base64 Linux command like this:
echo -n "XXX" | base64
Which displayed the base64 on 2 lines. So I removed the new line character to make it fit on one line in the yowsup config file.
In the config file, I only added the fields cc, phone, pushname, client_static_keypair like in the keyval example, is that enough? (I don't have the other fields and don't know how to get them, someone asked the question here also: https://github.com/tgalal/yowsup/issues/2829#issuecomment-508004084)
By the way I think there is a bug in the keyval example because there is a quote at the end of the client_static_keypair but I did not find one before (I guess quotes are not needed in the keyval format so I did not use them).

[bryanjhv]

Please at least share the stack trace. A simple GitHub search for "wrong length" returned no code matches so it might be from some of Yowsup's dependencies, would be useful to see. Apart from that, other error that I can think of is that the "echo" command must go with single quotes instead of double to avoid shell expansion, escaping and those things. Regarding the keyval example, I don't remember it correctly but I think quotes are needed (at the start and the end of the string) because it contains an "=" sign which could be misinterpreted by the parser (note: I might be wrong).

@bryanjhv here is the stack trace:

Traceback (most recent call last):

    raise ValueError("Wrong length: %d" % len(data))
ValueError: Wrong length: 86

If I use single quotes instead of double quotes with echo, the base64 result is the same.
The error is also displayed if I use quotes in the keyval config file.

[bryanjhv]

Here are the links relevant to the stack trace you provided.
https://github.com/tgalal/yowsup/blob/v3.2.3/yowsup/config/v1/serialize.py#L33
https://github.com/tgalal/consonance/blob/0.1.2/consonance/structs/keypair.py#L54
https://github.com/tgalal/dissononce/blob/0.34.3/dissononce/dh/x25519/keypair.py#L18-L19

After looking at keystore.xml file from WhatsApp, looks like it's already in base64 format but missing the required padding, which means adding = until the string length is 88 (as per https://stackoverflow.com/a/32140193 and given that keypair needs to have a length of 64).

Here's a script which could help (just adds the required "=" padding):

# save as pad.py and run:
# python pad.py '[keypair]'

from sys import argv, exit
from base64 import b64decode

if len(argv) != 2:
    print('ERROR: Missing keypair.')
    exit(1)

value = argv[1]
if len(value) > 88:
    print('ERROR: Invalid keypair.')
    exit(1)

print(value + (88 - len(value)) * '=')

NOTE: This does not guarantee that it will work or even be a valid one. I'm just helping with the validation. WhatsApp is banning most accounts so be careful, I'm not held responsible for you getting banned or someting, neither I am affiliated with someone here.

@bryanjhv thanks, since I don't use Android / iOS on my smartphone, I registered my phone number with the official WhatsApp Android app on my laptop using Anbox (it works using Android x86 in VirtualBox also). I read that they ban people who register with yowsup but anyway I don't really use WhatsApp since they don't provide a standalone web version that works without Android / iOS app.

The keypair was indeed already in base64 format, I just had to add 2 equals.
Now I get this error when trying to send a message with yowsup, do you have an idea what's wrong?

Update: @tgalal could it mean that yowsup does not work anymore because WhatsApp changed its API? I often see updates for the Android app that requires the user to download the new version.
