Implementations§

Source§

impl KeyStore

Source

pub fn new(kv: Arc<dyn KvStore>) -> Self

Source

pub async fn add_account(&self, secret_key: &Fr) -> Result<DerivedKeys, Error>

Add an account by storing its secret key, indexed by the public keys hash.

Source

pub async fn get_secret_key(&self, pk_hash: &Fr) -> Result<Option<Fr>, Error>

Get the secret key for an account identified by its public keys hash.

Source

pub async fn get_master_nullifier_hiding_key( &self, pk_hash: &Fr, ) -> Result<Option<GrumpkinScalar>, Error>

Get the master nullifier hiding key for an account.

Source

pub async fn get_master_incoming_viewing_secret_key( &self, pk_hash: &Fr, ) -> Result<Option<GrumpkinScalar>, Error>

Get the master incoming viewing secret key for an account.

Source

pub async fn get_master_outgoing_viewing_secret_key( &self, pk_hash: &Fr, ) -> Result<Option<GrumpkinScalar>, Error>

Get the master outgoing viewing secret key for an account.

Source

pub async fn get_master_tagging_secret_key( &self, pk_hash: &Fr, ) -> Result<Option<GrumpkinScalar>, Error>

Get the master tagging secret key for an account.

Source

pub async fn get_public_keys( &self, pk_hash: &Fr, ) -> Result<Option<PublicKeys>, Error>

Get the public keys for an account.

Source

pub async fn get_app_nullifier_hiding_key( &self, pk_hash: &Fr, app: &AztecAddress, ) -> Result<Option<Fr>, Error>

Compute the app-scoped nullifier hiding key.

Source

pub async fn get_key_validation_request( &self, pk_m_hash: &Fr, app: &AztecAddress, ) -> Result<Option<(Point, Fr)>, Error>

Find which account owns a given master public key hash, then return the corresponding public key point and app-siloed secret key.

Mirrors the TS getKeyValidationRequest(pkMHash, contractAddress).

Source

pub async fn get_app_secret_key( &self, pk_hash: &Fr, app: &AztecAddress, key_type: KeyType, ) -> Result<Option<Fr>, Error>

Compute an app-scoped secret key for a given key type.

Source

pub async fn get_app_ovsk( &self, pk_hash: &Fr, app: &AztecAddress, ) -> Result<Option<GrumpkinScalar>, Error>

Compute the app-scoped outgoing viewing secret key (returns GrumpkinScalar).

Source

pub async fn get_accounts(&self) -> Result<Vec<Fr>, Error>

List all stored public keys hashes.
