Struct diem_secure_storage::NamespacedStorage

source · 
pub struct NamespacedStorage { /* private fields */ }
Expand description

This provides a light wrapper around KV storages to support a namespace. That namespace is effectively prefixing all keys with then namespace value and “/” so a namespace of foo and a key of bar becomes “foo/bar”. Without a namespace, the key would just be “bar”. This matches how this library implements namespaces for Vault.

impl<T> CryptoStorage for T
where T: CryptoKVStorage,

source§

fn create_key(&mut self, name: &str) -> Result<BLSPublicKey, Error>

Securely generates a new named Consensus private key. The behavior for calling this interface multiple times with the same name is implementation specific.
source§

fn export_private_key(&self, name: &str) -> Result<BLSPrivateKey, Error>

Returns the Consensus private key stored at ‘name’.
source§

fn export_private_key_for_version( &self, name: &str, version: BLSPublicKey ) -> Result<BLSPrivateKey, Error>

Returns the Consensus private key stored at ‘name’ and identified by ‘version’, which is the corresponding public key. This may fail even if the ‘named’ key exists but the version is not present.
source§

fn import_private_key( &mut self, name: &str, key: BLSPrivateKey ) -> Result<(), Error>

An optional API that allows importing private keys and storing them at the provided name. This is not intended to be used in production and the API may throw unimplemented if not used correctly. As this is purely a testing API, there is no defined behavior for importing a key for a given name if that name already exists. It only exists to allow Diem to be run in test environments where a set of deterministic keys must be generated.
source§

fn get_public_key(&self, name: &str) -> Result<PublicKeyResponse, Error>

Returns the Consensus public key stored at ‘name’.
source§

fn get_public_key_previous_version( &self, name: &str ) -> Result<BLSPublicKey, Error>

Returns the previous version of the Consensus public key stored at ‘name’. For the most recent version, see ‘get_public_key(..)’ above.
source§

fn rotate_key(&mut self, name: &str) -> Result<BLSPublicKey, Error>

Rotates an Consensus private key. Future calls without version to this ‘named’ key will return the rotated key instance. The previous key is retained and can be accessed via the version. At most two versions are expected to be retained.
source§

fn sign<U>(&self, name: &str, message: &U) -> Result<BLSSignature, Error>
where U: CryptoHash + Serialize,

Signs the provided securely-hashable struct, using the ‘named’ private key.
source§

fn sign_using_version<U>( &self, name: &str, version: BLSPublicKey, message: &U ) -> Result<BLSSignature, Error>
where U: CryptoHash + Serialize,

Signs the provided securely-hashable struct, using the ‘named’ and ‘versioned’ private key. This may fail even if the ‘named’ key exists but the version is not present.
