Signal was a great example, and is open source. But this new backup mechanism greatly unwinds the core security guarantees that made it uniquely _higher_ security than most other applications. Before, a successful break in would impact only one conversation, and the moment key ratcheting from the counterparty occurred, the break in is stopped. But now, if the backup is successfully broken into, all past, present, and future conversations for that user are accessible. I created an interactive lab to demonstrate the differences of these encryption schemes here: https://quilibrium.com/labs/e2ee
