pub struct DeviceSynchronousProxy { /* private fields */ }

Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn program_key( &self, wrapped_key: &[u8], data_unit_size: u32, ___deadline: MonotonicInstant, ) -> Result<DeviceProgramKeyResult, Error>

Programs the ephemerally wrapped wrapped_key into the inline encryption hardware in the next available slot. All slots programmed via the connection this method is called on will be evicted once the connection is dropped. It is not possible to evict individual keys (not for any technical reasons; a need for this has not yet arisen). wrapped_key must be a key wrapped by the inline encryption hardware (in the same session/boot) via a separate mechanism to this protocol.

Returns

• ZX_ERR_NO_RESOURCES if there are no available key slots.
• ZX_ERR_INVALID_ARGS if wrapped_key is not the expected size or if the wrapped_key fails authentication (e.g. wrapped_key is from a previous boot).
• ZX_ERR_TIMED_OUT if the operation times out.
• ZX_ERR_INTERNAL if the operation failed for any other reason.

pub fn derive_raw_secret( &self, wrapped_key: &[u8], ___deadline: MonotonicInstant, ) -> Result<DeviceDeriveRawSecretResult, Error>

Derives a raw software secret from the ephemerally wrapped wrapped_key. wrapped_key must be a key wrapped by the inline encryption hardware (in the same session/boot) via a separate mechanism to this protocol. The returned secret can be used for non-inline cryptographic operations e.g. it can be used for encrypting filesystem metadata not covered by inline encryption. Returns

• ZX_ERR_INVALID_ARGS if wrapped_key is not the expected size or if the wrapped_key fails authentication (e.g. wrapped_key is from a previous boot).
• ZX_ERR_TIMED_OUT if the operation times out.
• ZX_ERR_INTERNAL if the operation failed for any other reason.
