我正在使用libreSSL v2.8.3在macbook上尝试openssl，并得到错误“没有证书匹配私钥”。我有一个域证书，2个中间证书和1个根证书。所以我使用以下命令成功地工作:

openssl pkcs12 -export -clcerts -inkey private.csr.key -in domain.name.crt -certfile intermediate1.crt -certfile intermediate2.crt -certfile root.crt -out domain.name.p12 -name "Your Name"

它将要求在导入过程中使用的密码。该命令将生成一个.p12文件，该文件可以重命名为.pfx，因为两者是相同的。

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!

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

(文章相关引语如下))

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

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。
