I was using the whalesong installing it with pip, but this was creating a lot of communicatino between other js modules I have running in my project. So, I want to ask if its ok to you if I create a simple Whalesong version (monitor messages and chats in the beginning), using you js script working with puppeteer?

I'll create a repo and publish in npm for others to use it, if it's ok.

It's perfect. In fact it is one of my todo's #39

Thanks! I'll add you as a collaborator, I'll be maintaining the repo, trying to keep up with the python version.

Hi, I'm having some trouble with media messages decryption, this one. Can you say what was the logic?

Thanks!

Well, I copied this code from https://github.com/tgalal/yowsup/issues/1449#issuecomment-377952926

But, more or less, this is the description:

L771: Download file L776: Get media key from message. Fill with '=' in order to complete b64 string (multiple of 3) L779: Compose crypto token (https://signal.org/docs/specifications/doubleratchet/#double-ratchet) L785: Split crypto token in order to get IV and KEY (https://github.com/tgalal/python-axolotl/blob/master/axolotl/util/byteutil.py#L26) L788: Remove last 10 bytes from file (I'm not sure why...) L790: Create decryptor with IV and KEY L792: Decrypt (AES-CBC: https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation) file and finalize (Maybe finalize is about last 10 bytes...)

May be, you could use https://github.com/signalapp/libsignal-protocol-javascript

Thanks, that works perfectly!
