Box 1: AzureServiceTokenProvider()

Box 2: tp.GetAccessTokenAsync( " .. " )

Acquiring an access token is then quite easy. Example code:

private async Task < string > GetAccessTokenAsync()

{

var tokenProvider = new AzureServiceTokenProvider();

return await tokenProvider.GetAccessTokenAsync( " https://storage.azure.com/ " );

}

Box 1: var key = await Resolver.ResolveKeyAsyn(keyBundle,KeyIdentifier.CancellationToken.None);

Box 2: var x = new BlobEncryptionPolicy(key,resolver);

Example:

// We begin with cloudKey1, and a resolver capable of resolving and caching Key Vault secrets.

BlobEncryptionPolicy encryptionPolicy = new BlobEncryptionPolicy(cloudKey1, cachingResolver);

client.DefaultRequestOptions.EncryptionPolicy = encryptionPolicy;

Box 3: cloudblobClient. DefaultRequestOptions.EncryptionPolicy = x;

Box 3: False

If you want to use the retry policy in Copy, and want the copy can be resume if break in the middle, you can use SyncCopy (isServiceCopy = false).
