EddsaSession class

The EddsaSession class offers APIs that facilitate easy access to Multi-Party Computation (MPC) functionalities.

Import

import 'package:silent_shard_sdk/silent_shard_sdk.dart' as sdk;

Usage

final cloudClient = sdk.CloudClient(
  baseUri: nodeUri,
  isSecure: false,
  webSocketClient: SocketExtended(),
);
final sessionConfig = sdk.SessionConfig(
  cloudClient: cloudClient,
  cloudVerifyingKeyHex: cloudVerifyingKey,
  protocol: sdk.Protocol.duo // Or use sdk.Protocol.trio for trio
);

await schnorr.init();

final session = sdk.EddsaSession(sessionConfig);

Keygen

final keyshare = await session.keygen();

Key refresh

final refreshedKeyshare = await session.refresh(keyshare: keyshare);

Signature generation

final signature = await session.sign(keyshare: keyshare, messageHash: messageHash);

Constructors

EddsaSession(SessionConfig config)
Creates a new EdDSA Session. SessionConfig config - The configuration for the session.

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

export({required SchnorrKeyshare keyshare}) → Future<Uint8List>
Exports a keyshare from the MPC to EdDSA private key. (Only trio)
import({required String privateKey, String? rootChainCode}) → Future<SchnorrKeyshare>
Import private key into MPC (client and server) keyshares
init() → Future<void>
Initialize the schnorr before using core functionalities, recommeneded to use it before any usage of EdDSA.
keygen() → Future<SchnorrKeyshare>
Generates a new EdDSA keyshare
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
recovery({required String publicKey}) → Future<SchnorrKeyshare>
Recover keyshare with public key in hex (only trio)
refresh({required String keyId}) → Future<SchnorrKeyshare>
Perform EdDSA keyrotation using schnorr.SchnorrKeyshare
sign({required String keyId, required String messageHash, String derivationPath = 'm'}) → Future<Uint8List>
Signs a message hash with the EdDSA keyshare
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
