Messenger by google

[flipbeats]

I was just curious if anybody here knew if Messenger by Google is encrypted. I ran into the article of this app called signal that is encrypted. I wasn't too sure messenger is though I've been using it for a good amount of time already. I just wanted to double check if anybody had any idea, I have searched for the answer but but I just get answers for hangouts and how it is encrypted but nothing for Messenger
.

Thanks!
