You can’t turn a low entropy key to a high entropy one by deterministic operations. It’s theoretically impossible.

- Retric 6y agoYes, what their doing is basically using a randomly generated key per device combined with the user generated key. So, it becomes a question of extracting the hidden key from the device or using the phone to brute force the decryption. However, without that key an attacker is stuck trying to brute force Apples high entropy key, which causes some confusion.
