I'm using latest commit

Remote files are now encrypted. To get image content, use message.getMediaContent() from master in my fork.

thundergreen · 2016-04-03T16:23:57Z

Sorry.don't understand well. I use your master. Which layer will I have to
modify?
Sorry for the noob question ;)

You can edit your top layer.py and implement:

def onMessage(self,message):
    if message.getType() == "media" and message.getMediaType() in ("image", "audio", "video"):
        with open("file","wb") as f:
            f.write(message.getMediaContent())

You can see more or less this code in cli/layer.py

Is this linke to this issue?

thundergreen · 2016-04-03T20:27:49Z

I really don't kniw what I have to do @jlguardi . i insert the code:

def onMessage(self,message):
if message.getType() == "media" and message.getMediaType() in ("image", "audio", "video"):
with open("file","wb") as f:
f.write(message.getMediaContent())

in layer: /usr/local/lib/python2.7/dist-packages/yowsup2-2.4.102-py2.7.egg/yowsup/layers/protocol_media/layer.py

but of course it fails :(

jlguardi · 2016-04-03T20:31:29Z

@thundergreen Do not edit layers if you aren't sure about what are you doing. Just edit your top level layer. For instance cli/layer.py or sendclient/layer.py.

thundergreen · 2016-04-03T20:50:50Z

Hi all, i have problms to get images decrypted:

i'm still getting that error with the current revision.

i'm using this code in transwhat and it looks like media.isEncrypted() returns False although the media is clearly encrypted.

Is there anything I could do to fix this?

nicolas-it · 2017-03-26T10:30:37Z

You might use some parts of https://github.com/jlguardi/yowsup
getExtension-method of common/tools.py

in folder layers/protocol_media/protocolentities/
message_media_downloadable.py
message_media_downloadable_image.py

I think this might help.

EDIT:
Or just see #1713

rigid · 2017-03-26T12:03:22Z

Thank you. But I can't see how that would make media.isEncrypted() return True as it should.

nicolas-it · 2017-03-27T19:14:07Z

I think 1aa1c55 of this PR implements your requested methods...

pabloruan0710 · 2017-03-27T19:28:00Z

worked fine for me! Thanks!!!

ajaybhatt17 · 2017-11-25T10:38:46Z

not clear abt mediaKey and cryptKeys ... can somebody help me understand it .. where i can find those data

o--- · 2018-03-30T20:00:42Z

Could somebody please clearly wrap up what needs to be do to get the image instead of a link to file.enc? Thank you in advance for your efforts.

albaizzz · 2018-04-02T04:10:25Z

@pabloruan0710 which solution did you use for decrypted .enc file to media ??

o--- · 2018-04-02T10:47:06Z

I did not use any solution so far. I am trying to find one, but so far I have not found anything that would be working from me / or I did not implement them right. I tried to replace files from different forks mentioned in various issues and now I am back to stock transwhat 0.2.2 + latest yowsup2.

albaizzz · 2018-04-02T14:50:48Z

@o--- is it work to upload send media and receive media on transwat 0.2.2 ?

pabloruan0710 · 2018-04-02T15:17:36Z

Hello Guys, I received every type files in my code using getMediaContent(), implement this three function in layers/protocol_media/protocolentities/message_media_downloadable.py:

Use this import and CRIPTKEYS in final of image:

After, add functions:

def decrypt(self, encimg, refkey):
        derivative = HKDFv3().deriveSecrets(refkey, binascii.unhexlify(self.cryptKeys), 112)
        parts = ByteUtil.split(derivative, 16, 32)
        iv = parts[0]
        cipherKey = parts[1]
        e_img = encimg[:-10]
        AES.key_size=128
        cr_obj = AES.new(key=cipherKey,mode=AES.MODE_CBC,IV=iv)
        return cr_obj.decrypt(e_img)

def isEncrypted(self):
        return self.cryptKeys and self.mediaKey

def getMediaContent(self):
        data = urlopen(self.url).read()
        if self.isEncrypted():
            data = self.decrypt(data, self.mediaKey)
        return bytearray(data)

Now, in layer use getMediaContent() for save image.

filename = "%s/%s%s"%(caminho_servidor, message.getId(), message.getExtension())
filenameurl = "%s/%s.jpg"%(caminho_servidor, message.getId())
with open(filename, 'wb') as f:
      f.write(message.getMediaContent())
            
try:
      im = Image.open(filename)
      im.save(filenameurl)
except Exception as e:  
      print("Erro ao gerar imagem %s"%e)

In message_media_downloadable_image.py:

def setImageProps(self, encoding, width, height, caption):
        self.encoding   = encoding
        self.width      = int(width)
        self.height     = int(height)
        self.caption    = caption
        self.cryptKeys  = '576861747341707020496d616765204b657973'

In message_media_downloadable_document.py:

def setDocumentProps(self, title, pages):
        self.pages      = int(pages)
        self.title      = title
        self.cryptKeys  = '576861747341707020446f63756d656e74204b657973'

In message_media_downloadable_audio.py:

def setAudioProps(self, abitrate = None, acodec = None, asampfreq = None,
                      duration = None, encoding = None, origin = None, seconds = None):
        self.abitrate  = abitrate
        self.acodec    = acodec
        self.asampfreq = asampfreq
        self.duration  = duration
        self.encoding  = encoding
        self.origin    = origin
        self.seconds   = seconds
        self.cryptKeys = '576861747341707020417564696f204b657973'

Thanks pabloruan0710.

My imports look a bit different in message_media_downloadable.py and when I changed them, I was getting No module name khdfv3.

I am also not sure how do you want me to implement in layer and in which layer?

What version python_axolotl your use? 0.1.35 ? @o---

I seem to be on 0.1.39.
I am using yowsup2.5.7 and current transwhat version from git.

The module issue mentioned above was a typo error.

Please,

where I can find the refkey value?

Thanks

viktor-sc · 2018-06-25T16:55:55Z

@pabloruan0710 Thanks for your post.
Could you specify where to add the code to the message_media_downloadable.py file and to the layer? And how exactly to get the keys?
Thanks in advance

nivaldodasilva · 2018-07-07T13:13:32Z

Is anyone knows how to get the refkey from axolotl.db?

Thank you
