Struct dkg_gadget::keystore::DKGKeystore
source · pub struct DKGKeystore(_, _);
Expand description
A DKG specific keystore implemented as a Newtype
. This is basically a
wrapper around [sp_keystore::Keystore
] and allows to customize
common cryptographic functionality.
Implementations§
source§impl DKGKeystore
impl DKGKeystore
pub fn new(keystore: Option<Arc<dyn Keystore>>, logger: DebugLogger) -> Self
pub fn new_default(logger: DebugLogger) -> Self
pub fn set_logger(&mut self, logger: DebugLogger)
Check if the keystore contains a private key for one of the public keys
contained in keys
. A public key with a matching private key is known
as a local authority id.
Return the public key for which we also do have a private key. If no
matching private key is found, None
will be returned.
sourcepub fn sr25519_public_key(&self, keys: &[Public]) -> Option<Public>
pub fn sr25519_public_key(&self, keys: &[Public]) -> Option<Public>
Check if the keystore contains a private key for one of the sr25519 public keys
contained in keys
. A public key with a matching private key is known
as a local authority id.
Return the public key for which we also do have a private key. If no
matching private key is found, None
will be returned.
sourcepub fn sign(&self, public: &Public, message: &[u8]) -> Result<Signature, Error>
pub fn sign(&self, public: &Public, message: &[u8]) -> Result<Signature, Error>
Sign message
with the public
key.
Note that message
usually will be pre-hashed before being signed.
Return the message signature or an error in case of failure.
sourcepub fn public_keys(&self) -> Result<Vec<Public>, Error>
pub fn public_keys(&self) -> Result<Vec<Public>, Error>
Returns a vector of [dkg_runtime_primitives::crypto::Public
] keys which are currently
supported (i.e. found in the keystore).
sourcepub fn sr25519_public_keys(&self) -> Result<Vec<Public>, Error>
pub fn sr25519_public_keys(&self) -> Result<Vec<Public>, Error>
Returns a vector of sr25519 Public keys which are currently supported (i.e. found in the keystore).
sourcepub fn sr25519_sign(
&self,
public: &Public,
message: &[u8]
) -> Result<Signature, Error>
pub fn sr25519_sign( &self, public: &Public, message: &[u8] ) -> Result<Signature, Error>
Sign message
with the sr25519 public
key.
Note that message
usually will be pre-hashed before being signed.
Return the message signature or an error in case of failure.
sourcepub fn verify(public: &Public, sig: &Signature, message: &[u8]) -> bool
pub fn verify(public: &Public, sig: &Signature, message: &[u8]) -> bool
Use the public
key to verify that sig
is a valid signature for message
.
Return true
if the signature is authentic, false
otherwise.
