Struct WrappedLocalUserDataKey 

pub(crate) struct WrappedLocalUserDataKey(pub(crate) EncString);

An indirect symmetric key for encrypting local user data (e.g. password generator history). Enables offline decryption of local data after a key rotation: only the wrapped key is re-encrypted; the local user data key itself stays intact.

Tuple Fields

0: EncString

Implementations

impl WrappedLocalUserDataKey

pub(crate) fn from_context_user_key( ctx: &mut KeyStoreContext<'_, KeySlotIds>, ) -> Result<Self, LocalUserDataKeyError>

Create a user key, wrapped by the user key.

pub(crate) fn rewrap_with_user_key( &self, old_wrapping_key_id: SymmetricKeySlotId, ctx: &mut KeyStoreContext<'_, KeySlotIds>, ) -> Result<Self, LocalUserDataKeyError>

Re-wrap an existing wrapped local user data key, preserving the inner key plaintext but changing the wrapping key from old_wrapping_key_id to the current SymmetricKeySlotId::User.

Used during V1→V2 user-key upgrades: the wrapped key was previously sealed with the V1 user key and must be re-sealed with the V2 user key so that local data encrypted under the local user data key remains decryptable after rotation.

pub(crate) fn unwrap_to_context( &self, ctx: &mut KeyStoreContext<'_, KeySlotIds>, ) -> Result<(), LocalUserDataKeyError>

Unwrap the local user data key and set it in the context under the SymmetricKeySlotId::LocalUserData key id.
