我从.key和.pem文件创建了.pfx文件。

比如这个openssl pkcs12 -inkey rootCA。输入rootCA。-export -out rootCA.pfx . pem

Windows不需要安装OpenSSL的解决方案

我最近试图解决同样的问题——我只有一台windows笔记本电脑，没有安装openssl(也没有足够的管理权限来安装它)。原来windows有一个内置的实用程序，叫做certutil，它能够将。crt和。key文件组合成。pfx。医生来了。

您需要创建一个新文件夹，并将.crt和关键文件放在其中。重命名两个文件，使其具有相同的名称(但扩展名不同):

{{sitename}}.crt
{{siteName}}.key

如果你的密钥文件是一个普通的txt -只是改变扩展名。key。

之后，在该文件夹中打开cmd并运行certutil -mergepfx [INPUTFILE] [OUTPUTFILE]

例子:

证书文件:“mySite.crt”

密钥文件:mySite.key

certutil命令:certutil -mergepfx mySite。crt mySite.pfx

注意:您将被要求为新创建的.pfx文件提供密码-不要忘记记忆/存储它-因为在目标系统上导入证书时将需要它。

如果您正在寻找Windows图形用户界面，请查看DigiCert。我只用了这个，非常简单。

在SSL选项卡下，我首先导入了证书。然后，一旦我选择了证书，我就可以将其导出为PFX，包括带或不带密钥文件。

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.

Next, you have to create the .pfx file that you will use to sign your deployments. Open a Command Prompt window, and type the following command: PVK2PFX –pvk yourprivatekeyfile.pvk –spc yourcertfile.cer –pfx yourpfxfile.pfx –po yourpfxpassword where: pvk - yourprivatekeyfile.pvk is the private key file that you created in step 4. spc - yourcertfile.cer is the certificate file you created in step 4. pfx - yourpfxfile.pfx is the name of the .pfx file that will be creating. po - yourpfxpassword is the password that you want to assign to the .pfx file. You will be prompted for this password when you add the .pfx file to a project in Visual Studio for the first time.

(可选的(不是为OP，而是为以后的读者)，你可以从头开始创建.cer和.pvk文件)(你会在上面之前这样做)。注意，mm/dd/yyyy是开始日期和结束日期的占位符。请参阅MSDN文章以获得完整的文档。

makecert -sv yourprivatekeyfile.pvk -n "CN=My Certificate Name" yourcertfile.cer -b mm/dd/yyyy -e mm/dd/yyyy -r

这是迄今为止最简单的转换方法。Cer到*。可以文件:

执行它，选择一个文件，并得到你的*.pfx!!
