C#和Node.jscrypto的通用加密解密代码示例

概述我试图在IIS中使用应用程序请求路由(ARR)将一组路径传递给Node.js网站.我的问题是能够在任何一方获得/设置身份验证票. 我真的需要一个加密/解密对的简单示例,它将适用于C#和Node.js,它们开箱即用,两者结果相同.在接下来的几天里,我将在时间允许的情况下自己解决这个问题,如果没有人在我面前提出答案,我打算回答. 我的目的是将节点侧写为Node.js端的connect / expres 我试图在IIS中使用应用程序请求路由(ARR)将一组路径传递给Node.Js网站.我的问题是能够在任何一方获得/设置身份验证票.

我的目的是将节点侧写为Node.Js端的connect / express模块​​.我已经在ASP.Net解决方案中进行了自定义身份验证,并且可以轻松地用两个平台上安全的东西替换我当前的方法(只要它们共享相同的密钥).

在AccountController.cs中创建身份验证cookie的当前代码

private voID ProcessUserLogin(MyEntityModel db,SiteUser user,bool remember=false){  var roles = String.Join("|",value:user.SiteRoles.Select(sr => sr.name.TolowerInvariant().Trim()).distinct().ToArray());  //update the laston record(s)  user.UserAgent = Request.UserAgent;  user.LastOn = DateTimeOffset.UtcNow;  db.SaveChanges();  // Create and tuck away the cookie  var authTicket = new FormsAuthenticationTicket(    1,user.Username,DateTime.Now,DateTime.Now.AddDays(31) //max 31 days,remember,string.IsNullOrWhiteSpace(roles) ? "guest" : roles  );  var ticket = FormsAuthentication.Encrypt(authTicket);  var cookie = new httpcookie(FormsAuthentication.Formscookiename,ticket);  if (remember) cookie.Expires = DateTime.Now.AddDays(8);  Response.cookies.Add(cookie);}

用于读取Global.asax.cs中的身份验证cookie的当前代码

voID Application_AuthenticateRequest(object sender,EventArgs args){  httpcookie authcookie = Context.Request.cookies[FormsAuthentication.Formscookiename];  if (authcookie == null) return;  FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authcookie.Value);  string[] roles = authTicket.UserData.Split(new Char[] { '|' });  //create new generic IDentity,and corresponding principal...  var g = new GenericIDentity(authTicket.name);  var up = new GenericPrincipal(g,roles);  //set principal for current request & thread (app will handle Transitions from here)  Thread.CurrentPrincipal = Context.User = up;}

Web.config的相关部分

<?xml version="1.0" enCoding="utf-8"?><configuration>  <system.web>    <membership>      <provIDers>        <!-- Remove default provIDer(s),so custom overrIDe works -->        <clear />      </provIDers>    </membership>  </system.web></configuration>

解决方法 这是一个使用DES算法的工作示例. reference

using System;using System.Text;using System.Security.Cryptography;public class Test{    public static string Encrypt(string toEncrypt,string key,bool useHashing)     {             byte[] keyArray;             byte[] toEncryptArray = UTF8EnCoding.UTF8.GetBytes(toEncrypt);              if (useHashing)             {                     MD5CryptoServiceProvIDer hashmd5 = new MD5CryptoServiceProvIDer();            keyArray = hashmd5.ComputeHash(UTF8EnCoding.UTF8.GetBytes(key));             }             else            keyArray = UTF8EnCoding.UTF8.GetBytes(key);              var tdes = new TripleDESCryptoServiceProvIDer();        tdes.Key = keyArray;             // tdes.Mode = CipherMode.CBC;  // which is default             // tdes.padding = paddingMode.PKCS7;  // which is default        Console.Writeline("iv: {0}",Convert.ToBase64String(tdes.IV));        ICryptotransform ctransform = tdes.CreateEncryptor();             byte[] resultArray = ctransform.transformFinalBlock(toEncryptArray,toEncryptArray.Length);              return Convert.ToBase64String(resultArray,resultArray.Length);     }      public static voID Main()    {        Console.Writeline("encrypted as: {0}",Encrypt("12345","abcdefghijklmnop",false));    }}

哪个输出

iv: pdMBMjdeFdo=encrypted as: 3uDkdT6aQ3c=

并在node.Js中使用正确的算法des-ede-cbc：

var crypto = require('crypto');var alg = 'des-ede-cbc';var key = new Buffer('abcdefghijklmnop','utf-8');var iv = new Buffer('pdMBMjdeFdo=','base64');var encrypted = new Buffer('3uDkdT6aQ3c=','base64');var source = '12345';var cipher = crypto.createCipheriv(alg,key,iv);var encoded = cipher.update(source,'ascii','base64');encoded += cipher.final('base64');console.log(encoded,encrypted.toString('base64'));var decipher = crypto.createDecipheriv(alg,iv);var decoded = decipher.update(encrypted,'binary','ascii');decoded += decipher.final('ascii');console.log(decoded,source);

哪个输出

3uDkdT6aQ3c= 3uDkdT6aQ3c=12345 12345
