c# - 在 C# 中以编程方式将 secret 添加到 Key Vault

Question

我正在尝试将我正在 Azure 的 Key Vault 中运行的服务的一些输出放入其中。我的服务的输出将是用户凭据，这就是我想使用 Key Vault 来实现此目的的原因。

到目前为止，我已经尝试了 KeyVaultClient 的 SetSecretAsync 方法，但它对我不起作用，我没有收到任何错误消息，但我也没有看到在我的目标 KeyVault 中创建的新 secret 。我无法找到 KeyVaultClient Add Secret 方法，因为它不存在，我在这里使用正确的对象/方法吗？

这里讨论的方法是AddResult。

这是我的代码:

    private static AzureKeyVault instance;
    private static KeyVaultClient client;
    private AzureKeyVault()
    {
        //initialize the azure key vault
        var vaultAddress = ConfigurationManager.AppSettings["VaultUri"];
        client = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetAccessToken));


    }
    public static async Task<string> GetAccessToken(string authority, string resource, string scope)
    {
        var clientId = ConfigurationManager.AppSettings["ClientID"];
        var clientSecret = ConfigurationManager.AppSettings["ClientSecret"];
        ClientCredential clientCredential = new ClientCredential(clientId, clientSecret);

        var context = new AuthenticationContext(authority, TokenCache.DefaultShared);
        var result = await context.AcquireTokenAsync(resource, clientCredential);

        return result.AccessToken;
    }


    public static AzureKeyVault GetInstance
    {
        get
        {
            if (instance == null)
            {
                instance = new AzureKeyVault();
            }
            return instance;
        }
    }

    public void AddResult(string machineIPAndPort, BruteForceResult result)
    {
        client.SetSecretAsync("https://vaultURI(redacted).vault.azure.net/", machineIPAndPort, JsonConvert.SerializeObject(result));
    }

要有耐心(等待创建)。

// Let's create a secret and read it back
string vaultBaseUrl = "https://alice.vault.azure.net";
string secret = "from-NET-SDK";

// Await SetSecretAsync
KeyVaultClient keyclient = new KeyVaultClient(GetToken);
var result = keyclient.SetSecretAsync(vaultBaseUrl, secret, "Sup3eS3c5et").Result;

// Print indented JSON response
string prettyResult = JsonConvert.SerializeObject(result, Formatting.Indented);
Console.WriteLine($"SetSecretAsync completed: {prettyResult}\n");

// Read back secret
string secretUrl = $"{vaultBaseUrl}/secrets/{secret}";
var secretWeJustWroteTo = keyclient.GetSecretAsync(secretUrl).Result;
Console.WriteLine($"secret: {secretWeJustWroteTo.Id} = {secretWeJustWroteTo.Value}");

结果:

SetSecretAsync completed:

{  
   "SecretIdentifier":{  
      "BaseIdentifier":"https://alice.vault.azure.net:443/secrets/from-NET-SDK",
      "Identifier":"https://alice.vault.azure.net:443/secrets/from-NET-SDK/59793...",
      "Name":"from-NET-SDK",
      "Vault":"https://alice.vault.azure.net:443",
      "VaultWithoutScheme":"alice.vault.azure.net",
      "Version":"597930b70565447d8ba9ba525a206a9e"
   },
   "value":"Sup3eS3c5et",
   "id":"https://alice.vault.azure.net/secrets/from-NET-SDK/59...",
   "contentType":null,
   "attributes":{  
      "recoveryLevel":"Purgeable",
      "enabled":true,
      "nbf":null,
      "exp":null,
      "created":1508354384,
      "updated":1508354384
   },
   "tags":null,
   "kid":null,
   "managed":null
}

secret: https://alice.vault.azure.net/secrets/from-NET-SDK/59793... = Sup3eS3c5et

你真正应该做的是重写AddResult():

public bool AddResult(string machineIPAndPort, BruteForceResult result)
{
    await result = client.SetSecretAsync("https://vaultURI(redacted).vault.azure.net/",
        machineIPAndPort, JsonConvert.SerializeObject(result));

    return true;
}

也许可以将其包装在 try-catch 中并读取自 that's where the meaningful HTTP response body will be 以来的 InnerException 。例如，针对我无权访问的 Key Vault 发出请求会导致:

而且因为这是云，您将与 other mission critical traffic 进行激烈的竞争，事情就会失败。
