创建X509Certificate2时是否阻止文件创建？

本文介绍了创建X509Certificate2时是否阻止文件创建？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

我们在ASP.NET应用程序中创建一个X509Certificate2对象以进行定期的传出连接。每次创建这些证书之一时，都会在以下位置创建一个新文件：

We create a X509Certificate2 object in our ASP.NET app to make periodic outgoing connections. Every time one of these certificates is created a new file is created in:

C：\ProgramData\Microsoft\Crypto\RSA\MachineKeys

C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys

该文件夹现在有400万个从未清除的文件。我试图删除Persist标志

That folder now has 4 million files that never get cleaned up. I've tried removing the Persist flag

新X509Certificate2（certBytes，p12Pwd， X509KeyStorageFlags.MachineKeySet）;

new X509Certificate2(certBytes, p12Pwd, X509KeyStorageFlags.MachineKeySet);

//否X509KeyStorageFlags.PersistKeySet

//no X509KeyStorageFlags.PersistKeySet

但这无济于事-每次调用仍然获得2Kb文件。

but that doesn't help -- still get the 2Kb file on every call.

当我看到这个答案，但这是一台2008 R2服务器，临时文件不是0字节，因此情况似乎有所不同。

I got my hopes up when I saw this answer, but this is a 2008 R2 server, and the temp files are not 0 bytes, so it seems to be a different case.

我们如何使用一个X509Certificate2而不填满磁盘？

How can we use a X509Certificate2 without filling up the disk?

推荐答案

使用.NET 4.6 ：

X509Certificate2实现了以开头的.NET的IDisposable接口。框架4.6;在.NET Framework的早期版本中，X509Certificate2类的不实现此接口，因此因此不存在Dispose方法。

X509Certificate2 implements the IDisposable interface starting with the .NET Framework 4.6; in previous versions of the .NET Framework, the X509Certificate2 class does not implement this interface, and therefore the Dispose method does not exist.
