Facebook has just posted the following type of WhatsApp in the Google Play Store betas program. As wabetainfo discovered in this version, the app can let you encrypt backup copies stored in Google Drive, something new that can be accessed on the iPhone.
It is written yes, but what about the copies?
The WhatsApp app writes content to auto-connect. Therefore, this information can only be read. sender and receiver
The ability to write content to backup content can mean, depending on how encryption is designed, the only way to access the contents of this service is closed. We do not currently know the details of this function in the developmental alpha phase. It should be noted that, while it seems reasonable that all WhatsApp customers enjoy the same level of security, the appearance on Android does not mean that it will come to the iPhone.
And is it a big change? It will. If we are concerned about the security of the content of our conversations, we may not do your backup. In doing so, however, remember to access our backup we only have one with Apple
It really is a feature that will be adopted, however, and if we are concerned about the privacy of our communications, there are alternatives such as Signal, an app used by the United States Senate for communication between employees.
