Direct Boot allows encrypted devices to boot straight to the lockscreen. The Android Key Store system lets you store cryptographic keys in a container to make it more difficult to extract from the device.Once keys are in the key store, they can be used for cryptographic operations with the key material remaining non-exportable.Moreover, it offers facilities to restrict when and how keys can be used, such as requiring user authentication for key use or restricting keys to be used only in certain cryptographic modes.With out it, before Android 18, you would need to create a file somewhere in your local or external device storage, where all of your keys would be kept (as you can understand, it is easy to extract that file).
