Spectacular implementation of end-to-end encryption.

I can take a picture of my W2 and send it to my tax person without worrying that it could be lost in an email hack. I can tell family members my last four of my social so they can get information on our cellphones. I can get password from family that I am doing computer work for.

Totally worth the money!
