Abstract
A computing device can perform operations to unlock encrypted volumes of the computing device while the computing device is in a recovery environment. In some examples, the computing device can work in conjunction with a test computing device to unlock the encrypted volumes using an unlock token and a PIN. In other examples, the computing device can perform operations without a test computing device. For example, the computing device can, while in the recovery environment, use credentials associated with a user of the computing device to obtain a recovery password to unlock keys for interpreting the encrypted volumes. In some examples, the computing device can use a shortened recovery password in conjunction with anti-hammering capabilities of a Trusted Platform Module in order to unlock keys for interpreting the encrypted volumes. These and other operations can facilitate secure unlock of volumes of encrypted data on a consumer device.
