This library provides a wrapper around indy_register_wallet_storage API that is not included in the official Indy SDK wrapper for .NET. The library exposes an interface that can be implemented to provide custom wallet storage. A sample in-memory implementation can be found in the tests project.

This package is available from myget.org.

Using package manager

PM> Install-Package Streetcred.Indy.Sdk.Storage -Source https://www.myget.org/F/streetcred-id/api/v3/index.json

Using dotnet cli

> dotnet add package Streetcred.Indy.Sdk.Storage --source https://www.myget.org/F/streetcred-id/api/v3/index.json 

You can also add custom nuget.config in your solution folder. See example here.

Implement IWalletStorage interface. See the sample implementation of InMemoryStorage.cs for general guidance. Note that the native Indy process runs all wallet access in a single thread, so you don't have to implement concurrency pattern since all calls are guaranteed to be sequential, but it may a good idea to do this anyway, in case anything changes.

Register the custom implementation using:

await Storage.RegisterWalletStorageAsync("my_storage", storageImplementation)

To use this with the Indy SDK, simply pass the storage type name to the Wallet.CreateAsync and Wallet.OpenAsync methods.

// Register storage type
var storage = new InMemoryStorage();
await Storage.RegisterWalletStorageAsync("inmem", storage);

// Create and open wallet
var config = JsonConvert.SerializeObject(new {id = "my_wallet", storage_type = "inmem"});
var creds = JsonConvert.SerializeObject(new {key = "secret_key"});

await  Wallet.CreateWalletAsync(config, creds);
var wallet = await Wallet.OpenWalletAsync(config, creds);
