RSA：在JavaScript加密密码，但未能解密，在C＃

本文介绍了RSA：在JavaScript加密密码，但未能解密，在C＃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我要的RSA加密应用到我的项目，但遇到一些麻烦：

I want apply the RSA encryption to my project, but encountered some troubles:

首先，我必须下载从$的的JavaScript库b $ b ，并添加引用到我的项目

二，我定义了RSA对象和代码初始化：

First, I have download the JavaScripts library fromhttp://www.ohdave.com/rsa/ ,and add reference to my project;
Second, I have define the RSA object and code to initialize that:

internal RSACryptoServiceProvider Rsa
    {
        get
        {
            if (HttpContext.Cache["Rsa"] != null)
            {
                RSACryptoServiceProvider encryptKeys = (RSACryptoServiceProvider)HttpContext.Cache["Rsa"];
                return encryptKeys;
            }
            else
            {
                return new RSACryptoServiceProvider(1024);
            }
        }
        set
        {
            HttpContext.Cache.Remove("Rsa");
            HttpContext.Cache.Insert("Rsa", value);
        }
    }
public ActionResult SignUp()
    {
        this.Rsa = Security.GetRsa();
        RSAParameters param= this.Rsa.ExportParameters(true);
        //this will bind to view
        TempData["exponent"] = Util.BytesToHexString(param.Exponent);
        TempData["key"] = Util.BytesToHexString(param.Modulus);

    UserInfo user = new UserInfo();
    user.Birthday = DateTime.Now.Date;
    return View(user);
}
private RSACryptoServiceProvider GetRsa()
    {
        RSACryptoServiceProvider Rsa = new RSACryptoServiceProvider(1024);
        return Rsa;
    }

3.then，JavaScript的身边，我有一些代码，它加密密码用户输入和绑定的控制权：

3.then, on JavaScript side , I have code, it encrypt the password user input and the bind it control:

var hash = document.getElementById("Pwd").value;
var exponent = document.getElementById("exponent").innerHTML;
var rsa_n = document.getElementById("key").innerHTML;
setMaxDigits(131);
var key = new RSAKeyPair(exponent, "", rsa_n);
hash = encryptedString(key, "111");

document.getElementById("Pwd").value = hash;
document.getElementById("Pwd2").value = hash;

document.getElementById("error").innerHTML = "";
document.getElementById("submit").click();

4.当用户点击提交，我的C＃代码得到加密的字符串PWD并试图对其进行解密，但失败，异常：坏数据：

4.when user click submit, my C# code get the encrypted pwd string and try to decrypt it but failed with exception: bad data:

[HttpPost]
    public ActionResult SignUp(UserInfo user)
    {
        user.UserId = user.UserId.ToLower(); //ignore case
        user.UserGUID = Guid.NewGuid();
        user.CreatedDate = DateTime.Now;
        user.IsEnabled = false;

        user.Pwd = Convert.ToBase64String(Rsa.Decrypt(Util.HexStringToBytes(user.Pwd), false));//Exception:Rsa.Decrypt throw bad data exception

谁你知道如何解决它？预先感谢您。

who do you know how to fix it? thank you in advance.
