Struct CryptProxy 

pub struct CryptProxy { /* private fields */ }

Implementations

impl CryptProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.fxfs/Crypt.

pub fn take_event_stream(&self) -> CryptEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn create_key( &self, owner: u64, purpose: KeyPurpose, ) -> QueryResponseFut<CryptCreateKeyResult, DefaultFuchsiaResourceDialect>

Creates a new key wrapped with the key identified by wrapping_key_id. owner identifies the owner of the key and must be supplied to UnwrapKey. The crypt service chooses a wrapping_key_id which must be supplied to UnwrapKey. The wrapping_key_id has no meaning to Fxfs. TODO(https://fxbug.dev/445189846): Add an object_type field to support inline encryption.

pub fn create_key_with_id( &self, owner: u64, wrapping_key_id: &[u8; 16], object_type: ObjectType, ) -> QueryResponseFut<CryptCreateKeyWithIdResult, DefaultFuchsiaResourceDialect>

Creates a new key wrapped with the key identified by wrapping_key_id. owner identifies the owner of the key and must be supplied to UnwrapKey along with wrapping_key_id. The wrapping_key_id has no meaning to Fxfs.

pub fn unwrap_key( &self, owner: u64, wrapped_key: &WrappedKey, ) -> QueryResponseFut<CryptUnwrapKeyResult, DefaultFuchsiaResourceDialect>

Unwraps a key. owner must be the same as that passed to CreateKey. This can fail due to permission reasons, but an incorrect key or owner will not fail; it will just return an unwrapped key that won’t actually decrpyt the data. ZX_ERR_UNAVAILABLE is returned if the key is known but cannot be unwrapped (e.g. it is locked). ZX_ERR_NOT_FOUND is returned if the key is not known. In some cases, implementations are unable to tell the difference between the two, in which case, ZX_ERR_UNAVAILABLE is returned.

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
