WhatsApp has announced this end-to-end security right now to prep the more comprehensive technical community along with the brand new strategy before it is available to beta testers and at some point to daily consumers.
WhatsApp brand-new feature will be released as an optionally available feature. In the coming weeks, the quick message system will be spinning this out to iOS and Android users.

Where will the key be saved?

The key is stored in the HSM Back-up Key Vault to allow the customer to recover the type when the unit is dropped or even swiped.
The HSM Data Backup Key Vault is in charge of applying code proof attempts and making the key completely inaccessible after a specific variety of unsuccessful efforts to access it.
