Whatsapp PHP api receiving encoded message

Question

I am using Whatsapp PHP api to send and receive messages.

When using my own phone number I am getting the message correctly, but using a friend's number sends an encrypted message. I got the issue on github.

$debug = true;
$username = '91xxxxxxxxxxx';
$password = "L9Djoxxxx+/HxxxxxWK3X24="; 
$nickname = 'SG'; 
$w = new WhatsProt($username, $nickname, $debug);
$w->connect();
$w->loginWithPassword($password);
$w->sendSetProfilePicture("demo/venom.jpg");
$s= $w->pollMessage();
for($i=0;$i<20;$i++){
      print($m->NodeString(""));
}

Here is one encoded message:

<message from="91xxxxxxxxxx@s.whatsapp.net" type="text" id="wsyC+kzW5JJv2" offline="0" t="1444469647" notify="Bikash">
  <enc v="1" type="pkmsg">3ýš²!øbƒÈÌl`¹$EÂ š‚A¹“"´®ä¾ì3Žvfx!    ?CgŸÙT×‚T¯Œp¶ìì.»ÓÊ¿~†6â…<"B3
!¶ÇIOÂóK†B(A=q”Ysþ¥(nrÎÏ(™‚jg"$4b’¸=Ç—j|HûS§³R(„Í¼0</enc>
</message>

have you changed the whatsapp password accordingly with the phone number?? — Nishant Solanki, Oct 03 '15 at 11:47
FYI : **if the number is registered newly, whatsapp server will send the message in an encrypted format!!! for old registered numbers it will remain unencrypted!** — Nishant Solanki, Oct 03 '15 at 11:55
yes. I am able to receive image and videos correct but only getting text message encoded. — Learner, Oct 03 '15 at 11:55
as they said the issue is resolved in previous versions of the API.. — Nishant Solanki, Oct 03 '15 at 12:47

@NanaPartykar do you want me to change character encoding... to UTF-8 — Learner, Oct 08 '15 at 05:32
I thought WhatsApp encryption depends on the phone's OS?? (iPhone has no encryption, Android has,..) rather than on the age of the number! — Daniel W., Jan 12 '16 at 15:51

According to the API changes (website) this issue started 17 nov.

17 Nov, 2014 Better encryption, more work for us!

Is not as easy to implement the 'encrypt' feature as i thought. WhatsApp has done a nice work this time (at least for now). We are working hard on this, and it will take time to us to implement this feature.

WhatsApp is using axolotl from WhisperSystems, you can check here.

We know more or less how it works, but as i said, this will take time for us. So be patient. We'll update you as we continue on this.

It should be solved at the current moment:

27 Dec, 2014 We did it!

It really has been a long time since we went to work on WhatsApp encryption, but we have finally did it! and it will be soon on the API, first it will appear in python API (yowsup) and later here in PHP.

The solution was to port the library.

I just wanted to give this good news and wish you a merry christmas.

I have the same problem. But now it is fixed. You can see their api. They have updated their api on github and fixed the encryption issue.

End to end encryption support: Now the API is able to encrypt and decrypt messages automatically

a using the one installed via Composer, I still see encrypted messages when I call `$w->GetMessages()'` – Volatil3 Apr 11 '16 at 09:58
This is my code: $w->pollMessage(); $msgs = $w->GetMessages(); foreach ($msgs as $m) { var_dump($m); } – Volatil3 Apr 11 '16 at 10:33
