While you can never be certain that WhatsApp uses e2e encryption without a proper source code review but you can do the following to atleast check it on your side by doing the following. 1. Install Charles webproxy 2. Configure your device to decrypt the https traffic of whatsapp ( install the ssl certificate and configure proxy) 2.5 Enable ssl proxy for whatsapp. 3. Monitor whatsapp's traffic using charles web proxy. 4. If you can see random encrypted text somewhere in the request or response they are using e2e encryption.

I'll try it tomorrow might even write about it here or somewhere depending on the results.
