我想推广“X证书和密钥管理器”或xca.exe，它就像OpenSSL的GUI版本。你可以通过以下步骤生成pfx文件:

在“private Keys”页签导入私钥; 在“Certificates”页签中导入证书; 生成pfx文件，选择证书，然后“导出”，格式选择PKCS #12。

就是这样。

你不需要openssl或makecert或任何。你也不需要CA给你的个人密钥。我几乎可以保证，问题是你希望能够使用CA提供的密钥和cer文件，但它们不是基于“IIS方式”。

SSL证书IIS与PFX一劳永逸- SSL和IIS解释- http://rainabba.blogspot.com/2014/03/ssl-certs-for-iis-with-pfx-once-and-for.html

Use IIS "Server Certificates" UI to "Generate Certificate Request" (the details of this request are out of the scope of this article but those details are critical). This will give you a CSR prepped for IIS. You then give that CSR to your CA and ask for a certificate. Then you take the CER/CRT file they give you, go back to IIS, "Complete Certificate Request" in the same place you generated the request. It may ask for a .CER and you might have a .CRT. They are the same thing. Just change the extension or use the . extension drop-down to select your .CRT. Now provide a proper "friendly name" (*.yourdomain.example, yourdomain.example, foo.yourdomain.example, etc..) THIS IS IMPORTANT! This MUST match what you setup the CSR for and what your CA provided you. If you asked for a wildcard, your CA must have approved and generated a wildcard and you must use the same. If your CSR was generated for foo.yourdomain.example, you MUST provide the same at this step.

我有你要求的链接。使用OpenSSL将CRT和KEY文件合并为PFX

以上连结摘录:

First we need to extract the root CA certificate from the existing .crt file, because we need this later. So open up the .crt and click on the Certification Path tab. Click the topmost certificate (In this case VeriSign) and hit View Certificate. Select the Details tab and hit Copy to File… Select Base-64 encoded X.509 (.CER) certificate Save it as rootca.cer or something similar. Place it in the same folder as the other files. Rename it from rootca.cer to rootca.crt Now we should have 3 files in our folder from which we can create a PFX file. Here is where we need OpenSSL. We can either download and install it on Windows, or simply open terminal on OSX.

编辑:

有一个支持链接，提供了关于如何安装证书的分步信息。 安装成功后，导出证书，选择.pfx格式，包含私钥。 重要提示:要以.pfx格式导出证书，您需要在请求证书的同一台机器上执行以下步骤。 导入的文件可以上传到服务器。

需要使用makecert工具。

以管理员身份打开命令提示符，输入以下命令:

makecert -sky exchange -r -n "CN=<CertificateName>" -pe -a sha1 -len 2048 -ss My "<CertificateName>.cer"

其中<CertifcateName> =要创建的证书的名称。

然后，您可以通过键入certmgr打开管理控制台的证书管理器管理单元。在开始菜单中，单击个人>证书>，您的证书应该可用。

我也有同样的问题。我的问题是，在扩展ssl验证过程完成之前，生成初始证书请求的计算机已经崩溃。我需要生成一个新的私钥，然后从证书提供者导入更新后的证书。如果您的计算机上不存在私钥，则不能将证书导出为pfx。这个选项是灰色的。

在大多数情况下，如果您无法将证书导出为PFX(包括私钥)，是因为MMC/IIS无法找到/没有访问私钥(用于生成CSR)的权限。以下是我解决这个问题的步骤:

Run MMC as Admin Generate the CSR using MMC. Follow this instructions to make the certificate exportable. Once you get the certificate from the CA (crt + p7b), import them (Personal\Certificates, and Intermediate Certification Authority\Certificates) IMPORTANT: Right-click your new certificate (Personal\Certificates) All Tasks..Manage Private Key, and assign permissions to your account or Everyone (risky!). You can go back to previous permissions once you have finished. Now, right-click the certificate and select All Tasks..Export, and you should be able to export the certificate including the private key as a PFX file, and you can upload it to Azure!

希望这能有所帮助!
