以编程方式将密钥添加到C#中的密钥保管库

Question

我试图从我在Azure的密钥保管库中运行的服务中输出一些输出.我的服务输出将是用户凭据,这就是我想为此目的使用Key Vault的原因.

到目前为止,我已经尝试过KeyVaultClient的SetSecretAsync方法,但它不适用于我,我没有收到任何错误消息,但是我也没有看到在我的目标KeyVault中创建的新秘密.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));
    }

使用耐心(等待创造).

// 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;
}

并且可能将其包装在一起try-catch并阅读,InnerException因为那是有意义的HTTP响应主体所在的位置.例如,针对密钥保管程序发出请求,我无权访问以下结果:

而且因为这是云,你正处于与其他关键任务流量的激烈竞争中,事情将会失败.
