Struct OsKeyring 

pub struct OsKeyring { /* private fields */ }

Real OS keyring backend ([host]). Stores the master key as a binary secret under a fixed service/user. Compiled on every platform behind the trait, but validated on real hardware in a later layer — unit tests use MockKeyring.

Implementations

impl OsKeyring

pub fn new() -> Self

The default kovra keyring entry (service = "kovra", user = "master-key").

Trait Implementations

impl Default for OsKeyring

fn default() -> Self

Returns the “default value” for a type.

impl Keyring for OsKeyring

fn get_master_key(&self) -> Result<MasterKey, CoreError>

Fetch the master key, materializing it (e.g. reading the OS keyring or deriving from a passphrase).

fn set_master_key(&self, key: &MasterKey) -> Result<(), CoreError>

Persist the master key (e.g. write it to the OS keyring). Backends that derive the key (see Argon2Keyring) have nothing to store and return an error.
