Key transport (wrapping) operations.

Required Methods

fn wrap( &mut self, key_id: &KeyId, wrapping_key_id: &KeyId, algorithm: WrapAlgorithm, ) -> Result<WrappedKey, BackendError>

Wrap key_id using wrapping_key_id with algorithm.

fn unwrap( &mut self, wrapped: &WrappedKey, unwrapping_key_id: &KeyId, label: &str, ) -> Result<KeyMetadata, BackendError>

Unwrap wrapped using unwrapping_key_id, importing the result with label.

Provided Methods

fn wrap_to_public( &mut self, key_id: &KeyId, recipient_pub_key: &[u8], algorithm: WrapAlgorithm, ) -> Result<WrappedKey, BackendError>

Wrap key_id to an external recipient’s raw public key.

Default implementation returns UnsupportedOperation.
