affinidi_tdk_vault 1.11.2

The Affinidi TDK Vault package provides libraries and tools for embedding Affinidi Vault into your existing Dart applications.

Affinidi TDK - Vault

The Affinidi TDK Vault package provides libraries and tools for embedding Affinidi Vault into your existing Dart applications. It implements the Self-Sovereign Identity (SSI), a fundamental concept of managing digital identities in a decentralised manner.

It allows you to manage multiple profiles representing your digital identity based on different contexts, including the data related to the profile stored in secure cloud storage; for example, you can have an identity for shopping, banking, or work.

Requirements

• Dart SDK version ^3.6.0

Installation

Run:

dart pub add affinidi_tdk_vault

or manually add the package to your pubspec.yaml file:

dependencies:
  affinidi_tdk_vault: ^<version_number>

Usage

After successfully installing the package, import it into your code.
(Note: the sample code below requires the installation of affinidi_tdk_vault_data_manager as a dependency.)

import 'dart:typed_data';

import 'package:affinidi_tdk_vault/affinidi_tdk_vault.dart';
import 'package:affinidi_tdk_vault_data_manager/affinidi_tdk_vault_data_manager.dart';

void main() async {
  // Initialise InMemory storage
  final accountIndex = 0;
  final vaultStore = InMemoryVaultStore();
  await vaultStore.writeAccountIndex(accountIndex);

  // Generate seed from the storage layer
  final seed = vaultStore.getRandomSeed();
  await keyStorage.setSeed(seed);

  // Initialise profile interface
  const vfsRepositoryId = 'vfs';
  final profileRepositories = <String, ProfileRepository>{
    vfsRepositoryId: VfsProfileRepository(vfsRepositoryId),
  };

  // Create vault from vault store
  final vault = await Vault.fromVaultStore(
    keyStorage,
    profileRepositories: profileRepositories,
    defaultProfileRepositoryId: vfsRepositoryId,
  );

  // Must initialize vault before being able to access any of the repositories
  await vault.ensureInitialized();
}

Note: The example above uses VfsProfileRepository from the affinidi_tdk_vault_data_manager package to enable cloud storage functionality. If you only need local storage or custom implementations, you can use just the core vault package.
