Enum KeyPurpose

Source 
pub enum KeyPurpose {
    Data,
    Metadata,
}
Expand description

Different keys are used for metadata and data in order to make certain operations requiring a metadata key rotation (e.g. secure erase) more efficient.

Variants§

§

Data

The key will be used to wrap user data.

§

Metadata

The key will be used to wrap internal metadata.
