使用javascript加密并使用AES算法在C＃中解密 [英] Encrypt in javascript and decrypt in C# with AES algorithm

问题描述

我尝试使用AES库中的 AES 。

I tried to encrypt in angular using AES library from AES.

我使用 CryptoJS加密了字符串AES中的.AES.encrypt（）方法。

这是我的代码：

  var txtloginKod = 'Some String...';             
  var key = CryptoJS.enc.Utf8.parse('8080808080808080');
  var iv = CryptoJS.enc.Utf8.parse('8080808080808080');
  var  encryptedlogin = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse(txtloginKod), key,
  {
      keySize: 128 / 8,
      iv: iv,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
  });

方法 CryptoJS.AES.encrypt（）将对象返回到我的 encryptedlogin 变量。

The method CryptoJS.AES.encrypt() return a Object to my encryptedlogin variable.

我不知道如何将该对象发送到WCF。 C＃中的Web服务器

I don't know how to send this object to my WCF Web server in C#

当我尝试发送整个对象（并定义Web服务方法以期望获得C＃对象）时，出现以下错误：

When I tried to send the whole object (and define the Web service method to expect get C# Object), I got the error below:

将循环结构转换为JSON

"Converting circular structure to JSON"

推荐答案

我也有要求将加密的JSON对象发送到.Net CORE API 2.0，并在Internet上进行搜索以查找是否有帮助。我知道现在您已经解决了这个问题，但是为了帮助有兴趣的人，我将提供我的解决方案来帮助他们。

I too had the requirement to send encrypted JSON object to .Net CORE API 2.0 and searched on internet to find if there is any help. I know by now you would have solved this issue but to help anyone interested I am providing my solution to help them.

借助在stackoverflow上找到的示例代码，我设法实施了解决方案。棘手的位是关键，代码的长度必须为16，IV才能正常工作。

With the sample codes I found here on stackoverflow, I managed to implement the solution. The tricky bit is the key and IV has to be 16 in length for the code to work.

public static encrypt(model: any) {
        const key = CryptoJS.enc.Utf8.parse('TestMyOwnKeyForI');
        const iv = CryptoJS.enc.Utf8.parse('TestMyOwnIV1ForI');
        // padding and truncating
        const encryptedMessage = CryptoJS.AES.encrypt(JSON.stringify(model), key, {            
            keySize: 128 / 8,
            iv: iv,
            mode: CryptoJS.mode.CBC,
            padding: CryptoJS.pad.Pkcs7
        }).toString();

        return encryptedMessage;
}

在CORE中，我实现了如下的客户模型绑定提供程序：

In CORE I've implemented my customer model binding provider as follows:

public class DecryptModelBinderProvider : IModelBinderProvider
    {
        public IModelBinder GetBinder(ModelBinderProviderContext context)
        {
            if (context.Metadata.ModelType == typeof(MyModel))
                return new DecryptModelBinder();

            return null;
        }
    }

然后我自己的解密模型绑定器如下：

Then my own decryptmodelbinder as follows:

public class DecryptModelBinder : IModelBinder
    {
        public Task BindModelAsync(ModelBindingContext bindingContext)
        {
            if (bindingContext == null)
                throw new ArgumentNullException(nameof(bindingContext));
            using (var sr = new StreamReader(bindingContext.HttpContext.Request.Body))
            {
                string valueFromBody = sr.ReadToEnd();

                if (valueFromBody != null && valueFromBody.Length > 0)
                {
                    var decrypted = Encryption.DecryptString(valueFromBody, "TestMyOwnKeyForI");

                    var model = JsonConvert.DeserializeObject(decrypted, bindingContext.ModelType);

                    bindingContext.Result = ModelBindingResult.Success(model);
                    bindingContext.Model = model;        
                }

            }

            return Task.CompletedTask;
        }
    }
