Jun 17, 2016 at 16:46 comment added TessellatingHeckler @HenriqueJung It would not mean that. The message would be encrypted to her private key, Whatsapp can store the message, but cannot read it. Her private key is encrypted by her password, Whatsapp can store the private key but not use it. She can download both (with her account username and password), unlock the private key locally on her phone (with her account password ... which she just gave Whatsapp during login ... oh. I think I see the problem now.

Jun 16, 2016 at 3:03 comment added TessellatingHeckler I'm not familiar with WhatsApp; Could a user's private key be stored on WhatsApp's servers, encrypted with their login password, so you reinstalled WhatsApp, she logged in, downloaded and decrypted the settings including her account's private key, and then could read the group messages?
