检索ASP.Net自动生成的machineKey [英] Retrieve ASP.Net AutoGenerated MachineKey

问题描述

我有一个.net 1.1应用程序，必须升级到2.0。该应用程序使用MD5CryptoServiceProvider数据库加密密码。之后我升级到2.0的MD5值不同。在machine.config中，将machineKey设置为自动生成。

I have a .Net 1.1 app that must be upgraded to 2.0. The application encrypts passwords in the database using MD5CryptoServiceProvider. After I upgraded to 2.0, the MD5 value was different. In the machine.config, the machinekey was set to autogenerate.

有没有一种方法来检索此键？

Is there a way to retrieve this key?

推荐答案

的<一个href=\"http://msdn.microsoft.com/en-us/library/system.security.cryptography.md5cryptoserviceprovider.aspx\"相对=nofollow> System.Security.Cryptography.MD5CryptoServiceProvider 不依赖于ASP.NET 的System.Web / machineKey中设置。这些都是用来控制篡改打样和ViewState的加密，窗体身份验证票和作用饼干（的如何：在ASP.NET 2.0 ）配置的machineKey

The System.Security.Cryptography.MD5CryptoServiceProvider doesn't rely on the ASP.NET system.web/machineKey settings. These are used to control tamper proofing and encryption of ViewState, forms authentication tickets, and role cookies (How To: Configure MachineKey in ASP.NET 2.0).

我刚刚编译下.NET 1.1和2.0执行一个MD5哈希一个简单的控制台应用程序，它们都产生相同的值。我跑了两个不同计算机上这些应用程序（一个自动生成机键，和一个硬codeD键），再次，相同的结果。

I just compiled a simple console application under .NET 1.1 and 2.0 that performs a MD5 hash and they both produce the same value. I ran these applications on two different machines (one with autogenerated machine keys, and one with hard coded keys), again, identical results.

这听起来像使用的编码可能是不同的，即1.1应用程序使用 ASCIIEncoding 和2.0应用程序正在使用的Uni code 。

This sounds like the Encoding used is possibly different, i.e. the 1.1 application is using ASCIIEncoding and the 2.0 application is using Unicode.

要检查的另一件事是，如果要生成您使用的是使用你已经忘记了盐，肯定会导致不同的散列的方法。

Another thing to check is if the method you're using a uses salt that you've forgotten about, that would certainly cause different hashes to be generated.
