如何在appsettings.json asp.net核心中加密/解密字段/对象

Question

我想在appsetings.json中加密连接字符串并在将它传递给ConfigureServices方法中的options.UseSqlServer（Configuration [＆＃34; Database：Connection＆＃34;]）之前解密。不幸的是，在互联网上关于asp.net核心的内容并不多。连接字符串如下所示：

    "Database": {
    "Connection": "string"

  }

我可能也喜欢和其他设置对象一样，以下是到目前为止我已经四处寻找，但我想我迷路了。任何建议，高度赞赏。谢谢。

public class CustomConfigProvider : ConfigurationProvider, IConfigurationSource
{
    public CustomConfigProvider()
    {

    }

    public override void Load()
    {
        Data = UnencryptMyConfiguration();
    }

    private IDictionary<string, string> UnencryptMyConfiguration()
    {
        // do whatever you need to do here, for example load the file and unencrypt key by key
        //Like:
        var configValues = new Dictionary<string, string>
        {
            {"Database", "string"}

        };
        return configValues;
    }

    private IDictionary<string, string> CreateAndSaveDefaultValues(IDictionary<string, string> defaultDictionary)
    {
        var configValues = new Dictionary<string, string>
        {
            {"Database", "string"},

        };
        return configValues;
    }
    public IConfigurationProvider Build(IConfigurationBuilder builder)
    {
        return new CustomConfigProvider();
    }
}
