fn is_available() -> bool

Check if this backend is available on the current system.

fn generate_data_key(&mut self) -> Result<WrappedKey>

Generate a Data Key and wrap it with the Primary Key. The returned WrappedKey blob cannot be unwrapped without the TEE.

fn seal(&mut self, _key: &WrappedKey, _data: &[u8]) -> Result<Vec<u8>>

Unwrap the Data Key, encrypt data, and seal with PCR policy.

fn unseal(&mut self, _key: &WrappedKey, _sealed: &[u8]) -> Result<Vec<u8>>

Unseal data. Fails if PCR values have changed.

fn backend_type(&self) -> BackendType

Return the backend type identifier.
