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。

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。

这是迄今为止最简单的转换方法。Cer到*。可以文件:

只需从DigiCert下载便携式证书转换器: https://www.digicert.com/util/pfx-certificate-management-utility-import-export-instructions.htm

执行它，选择一个文件，并得到你的*.pfx!!

(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

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.

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。
