Project: Whatsapp Sniffer

Hey Guys,
As u probably know whatsapp is the less secure chat client on mobile devices.
So I thought of developing of course with your help guys a program that will automate the collect of all messages sent and received.
My idea is as following:
- Create a Program that will allie and automate all the steps sited bellow
1-Collect all the packets that are destinated to whatsapp server or received from whastapp serers ( a little wireshark)
2- take all these packets and transform them to plain text (easy peasy) because the messages are transited in plain text without any encryption.
I hope u can help me guys create this for making it availble to anyone willing to know what is being sent from there wifi.

WhatsApp is using encryption for quite some time now. AFAIK the key is a mixture of the devices IMEI and a password the server sends you.

If it would still be that easy, then there would already be a lot of apps out there doing that...

If you search you will find the exploits of whatsapp
