Struct MasterKeyring 

pub struct MasterKeyring { /* private fields */ }

A store’s master key material: every key it holds. This is the value custody implementations store, unlock, and re-protect — never a cipher. coven builds the EncryptionService cipher from it internally; custody never touches cipher machinery.

Implementations

impl MasterKeyring

pub fn generate() -> MasterKeyring

One fresh generation-1 key.

pub fn to_serialized(&self) -> String

Serialize to the stored keyring JSON — the same format EncryptionService::to_keyring_string produces, since every generation this type holds came from (or feeds) that cipher.

pub fn from_serialized(s: &str) -> Result<MasterKeyring, EncryptionError>

Parse the stored master-key format Self::to_serialized produces.

pub fn fingerprint(&self) -> String

SHA-256 fingerprint of the seal key (the deterministically selected key this keyring seals new data under), first 8 bytes hex-encoded. Short enough to display in UI, long enough to detect wrong keys.
