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.

如果需要，可以在OpenSSL中使用这个简单的命令序列来生成filessl。key (SSL证书密钥文件)、filessl. key和filessl. key。SSL证书文件:

openssl genrsa 2048 > filessl.key
chmod 400 filessl.key
openssl req -new -x509 -nodes -sha256 -days 365 -key filessl.key -out filessl.crt

在此之前，您必须响应交互式表单(您可以从其他帖子中找到类似req.cnf的参考信息:https://stackoverflow.com/a/49784278/7856894)

然后，继续执行最后一个命令，它会要求您输入Export Password:

openssl pkcs12 -export -out filessl.pfx -inkey filessl.key -in filessl.crt

准备好了，它生成了.pfx(或. p12)格式的SSL证书文件:

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”。

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!!

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。

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
