X509Certificate2使IIS崩溃 [英] X509Certificate2 makes IIS crash

问题描述

在newing了X509Certificate2实例（字符串，字符串）我的IIS进程只是崩溃。没有的.NET异常，什么都没有，这只是我的事件日志

When newing up an instance of X509Certificate2(string, string) my IIS process simply crashes. No .Net exception, no nothing, except of this in my event log

林pretty的目瞪口呆，不知道从哪里开始寻找。当附加调试器的过程中，我能够对这个换行，但跨过它时，整件事崩溃。

Im pretty stunned and don't know where to start looking. When attaching a debugger to the process, i'm able to break unto this line, but when stepping over it the the whole thing crashes.

    _certificate = new X509Certificate2(pfxFile, pfxPassword);

pfxFile是一个有效的路径，如果我改变它，我立即得到一个正确的.Net PathNotFound例外。

pfxFile is a valid path, if i change it i immediately get a correct .Net PathNotFound exception.

服务器是Windows 2012，运行IIS8和.NET 4.5。

Server is Windows 2012, running IIS8 and .Net 4.5.

Update: This article describes the same problem where a solution is to make sure the App Pool identity has LoadUserProfile enabled.

推荐答案

我也有类似的问题，也是Windows Server 2012中，它坠毁IIS上，在使用

I had a similar problem, also on Windows Server 2012, which crashed IIS, when using

new X509Certificate2(fileName, keyPassword, X509KeyStorageFlags.Exportable)

这是固定的，通过改变构造

This was fixed by changing the constructor to

new X509Certificate2(fileName, keyPassword, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable)
