在 Azure 上存储和使用现有的数据保护密钥

Question

我正在尝试使用 azure 云设置在本地密钥上同步，以便两个环境都可以解密授权标头访问令牌。

目前我有这个设置：

将此格式的现有 xml 密钥文件添加到 Azure Blob 存储：

<?xml version="1.0" encoding="utf-8"?>
<key id="id..." version="1">
<creationDate>2018-05-08T17:44:54.9313191Z</creationDate>
<activationDate>2018-05-08T17:44:54.8979462Z</activationDate>
<expirationDate>2023-05-07T17:44:54.8979462Z</expirationDate>
<descriptor deserializerType="Microsoft.AspNetCore.DataProtection.AuthenticatedEncryption.ConfigurationModel.AuthenticatedEncryptorDescriptorDeserializer, Microsoft.AspNetCore.DataProtection, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60">
<descriptor>
<encryption algorithm="AES_256_CBC" />
<validation algorithm="HMACSHA256" />
<masterKey p4:requiresEncryption="true" xmlns:p4="http://schemas.asp.net/2015/03/dataProtection">
<!-- Warning: the key below is in an unencrypted form. -->
<value>my-shared-key</value>
</masterKey>
</descriptor>
</descriptor>
</key>

在应用启动期间注册了密钥，如下所示：

services.AddDataProtection()
.SetApplicationName("common-app-name")
.DisableAutomaticKeyGeneration()
.PersistKeysToAzureBlobStorage(new Uri("my uri/sas"));

在启动期间看到以下警告/错误：

fail: Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingProvider[48]

我哪里出错了？

提前谢谢。

更新：

还尝试了这种注册 azure 密钥的方法，但仍然看到相同的错误：

var storageAccount = CloudStorageAccount.Parse("<connectionstring + access key>");
var client = storageAccount.CreateCloudBlobClient();
var container = client.GetContainerReference("dev");
container.CreateIfNotExistsAsync().GetAwaiter().GetResult();
services.AddDataProtection()
.SetApplicationName("common-name")
.PersistKeysToAzureBlobStorage(container, "keys.xml")
.DisableAutomaticKeyGeneration();

最终自己找到了答案，不幸的是，此信息没有记录在任何地方的MS Azure Docs中。

简单地说，您需要将关键的xml元素包装在根<repository></repository>元素中。
