Create a new file using Notepad. Paste the information into the new Notepad file. Save the file as certificate.crt. Notepad should save this file as certificate.crt.txt. Rename the new Notepad file extension to.crt. Creating your privateKey.key file: Return. On some platforms, OpenSSL will save the.key file to the same directory from where the –req command was run. If you have yet to install the certificate and cannot find the key, it’s possible it’s gone. If you created the CSR but cannot locate your key file, the easiest thing to do is reissue your certificate. To open it in plain text, you will need to click on the name of the entry and scroll down until the key code appears on the screen. Alternatively, you can click on the green arrow sign on the right and download the.pem file containing the key, the CSR and the certificate along with the CA bundle, if they were imported already. I have received a p7b file from my co-worker and he asked me to install it on one of our servers. It looks like p7b is same as.cert file. I looked up google to find out how to install the file and it looks like I also need to have.key file. Is it possible to make the key file with.cert or.p7b file?

I need .pfx file to install https on website on IIS.

I have two separate files: certificate (.cer or pem) and private key (.crt) but IIS accepts only .pfx files.

I obviously installed certificate and it is available in certificate manager (mmc) but when I select Certificate Export Wizard I cannot select PFX format (it’s greyed out)

Are there any tools to do that or C# examples of doing that programtically?

If you’re looking for a Windows GUI, check out DigiCert. I just used this and it was fairly simple.

Under the SSL tab, I first Imported the Certificate. Then once I selected the Certificate I was able to export as a PFX, both with and without a keyfile.

Answers:

You do NOT need openssl or makecert or any of that. You also don’t need the personal key given to you by your CA. I can almost guarantee that the problem is that you expect to be able to use the key and cer files provided by your CA but they aren’t based on “the IIS way”. I’m so tired of seeing bad and difficult info out here that I decided to blog the subject and the solution. When you realize what’s going on and see how easy it is, you will want to hug me 🙂

SSL Certs for IIS with PFX once and for all – SSL and IIS Explained – 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.com, yourdomain.com, foo.yourdomain.com, 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.com, you MUST provide the same at this step.

I got a link with your requirement.Combine CRT and KEY Files into a PFX with OpenSSL

Extracts from the above link:

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.

EDIT:

  1. There is a support link with step by step information on how to do install the certificate.

  2. After successfully install, export the certificate, choose .pfx format, include private key.

    Important Note: : To export the certificate in .pfx format you need to follow the steps on the same machine from which you have requested the certificate.

  3. The imported file can be uploaded to server.

Answers:

You need to use the makecert tool.

Open a command prompt as admin and type the following:

Where <CertifcateName> = the name of your cert to create.

Then you can open the Certificate Manager snap-in for the management console by typing certmgr.msc in the Start menu, click personal > certificates > and your cert should be available.

Here is an article.

Answers:

This is BY FAR the easiest way to convert *.cer to *.pfx files:

Just download the portable certificate converter from DigiCert:
https://www.digicert.com/util/pfx-certificate-management-utility-import-export-instructions.htm

Execute it, select a file and get your *.pfx!!

Answers:

When you say the certificate is available in MMC, is it available under “Current User” or “Local Computer”? I’ve found that I can only export the private key if it is under Local Computer.

You can add the snap in for Certificates to MMC and choose which account it should manage certificates for. Choose Local Computer. If your certificate is not there, import it by right clicking the store and choosing All Tasks > Import.

Now navigate to your imported certificate under the Local Computer version of the certificate snap in. Right click the certificate and choose All Tasks > Export. The second page of the export wizard should ask if you want to export the private key. Select Yes. The PFX option will now be the only one available (it is grayed out if you select no and the option to export the private key isn’t available under the Current User account).

You’ll be asked to set a password for the PFX file and then to set the certificate name.

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:

where:

(Optionally (and not for the OP, but for future readers), you can create the .cer and .pvk file from scratch) (you would do this BEFORE the above). note the mm/dd/yyyy are placeholders for start and end dates. see msdn article for full documentation.

Answers:

I was having the same issue. My problem was that the computer that generated the initial certificate request had crashed before the extended ssl validation process was completed. I needed to generate a new private key and then import the updated certificate from the certificate provider. If the private key doesn’t exist on your computer then you can’t export the certificate as pfx. They option is greyed out.

Answers:

I know a few users have talked about installing this and that and adding command lines programmes and downloading…

Personally I am lazy and find all these methods cumbersome and slow, plus I don’t want to download anything and find the correct cmd lines if I don’t have to.

Best way for me on my personal IIS server is to use RapidSSLOnline. This is a tool that’s on a server allows you to upload your certificate and private key and is able to generate a pfx file for you that you can directly import into IIS.

The link is here:
https://www.rapidsslonline.com/ssl-tools/ssl-converter.php

Below is the steps used for the scenario requested.

  1. Select Current Type = PEM
  2. Change for = PFX
  3. Upload your certificate
  4. Upload your private key
  5. If you have ROOT CA cert or intermediate certs upload them too
  6. Set a password of your choosing, used in IIS
  7. Click the reCaptcha to prove you’re not a bot
  8. Click Convert

And that’s it you should have a PFX downloaded and use this in your Import process on IIS.

Hope this helps other like minded, lazy tech people.

Answers:

In most of the cases, if you are unable to export the certificate as a PFX (including the private key) is because MMC/IIS cannot find/don’t have access to the private key (used to generate the CSR). These are the steps I followed to fix this issue:

  • 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 (PersonalCertificates, and Intermediate Certification AuthorityCertificates)
  • IMPORTANT: Right-click your new certificate (PersonalCertificates) 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!

Hope this helps!

Answers:

Although it is probably easiest to generate a new CSR using IIS (like @rainabba said), assuming you have the intermediate certificates there are some online converters out there – for instance:
https://www.sslshopper.com/ssl-converter.html

This will allow you to create a PFX from your certificate and private key without having to install another program.

Important: This example is intended to provide general guidance to IT professionals who are experienced with SSL requirements and configuration. The procedure described in this article is just one of many available methods you can use to generate the required files. The process described here should be treated as an example and not as a recommendation.

When you configure Tableau Server to use Secure Sockets Layer (SSL) encryption, this helps ensure that access to the server is secure and that data sent between Tableau Server and Tableau Desktop is protected.

Looking for Tableau Server on Linux? See Example: SSL Certificate - Generate a Key and CSR.

Tableau Server uses Apache, which includes OpenSSL. You can use the OpenSSL toolkit to generate a key file and Certificate Signing Request (CSR) which can then be used to obtain a signed SSL certificate.

Steps to generate a key and CSR

To configure Tableau Server to use SSL, you must have an SSL certificate. To obtain the SSL certificate, complete the steps:

  1. Generate a key file.
  2. Create a Certificate Signing Request (CSR).
  3. Send the CSR to a certificate authority (CA) to obtain an SSL certificate.
  4. Use the key and certificate to configure Tableau Server to use SSL.

You can find additional information on the SSL FAQ page on the Apache Software Foundation website.

How

Configure a certificate for multiple domain names

Tableau Server allows SSL for multiple domains. To set up this environment, you need to modify the OpenSSL configuration file, openssl.conf, and configure a Subject Alternative Name (SAN) certificate on Tableau Server. See For SAN certificates: modify the OpenSSL configuration file below.

Set the OpenSSL configuration environment variable (optional)

To avoid using the -config argument with every use of openssl.exe, you can use the OPENSSL_CONF environment variable to ensure that the correct configuration file is used and all configuration changes made in subsequent procedures in this article produce expected results (for example, you must set the environment variable to add a SAN to your certificate).

Open the Command Prompt as an administrator, and run the following command:

set OPENSSL_CONF=c:Program FilesTableauTableau Serverpackagesapache.<version_code>confopenssl.cnf

Notes:

  • When setting the Open SSL configuration environment variable, do not enclose the file path with quotation marks.

  • If you are using a 32-bit version of Tableau Server on a 64-bit computer, run the set OPENSSL_CONF=c:Program Files (x86)TableauTableau Serverpackagesapache.<version_code>confopenssl.cnf command instead.

Generate a key

Generate a key file that you will use to generate a certificate signing request.

  1. Open the Command Prompt as an administrator, and navigate to the Apache directory for Tableau Server. For example, run the following command:

    cd C:Program FilesTableauTableau Serverpackagesapache.<version_code>bin

Crysis3 Beta Keys Generator. Crysis 3 is a first-person shooter video game under development by Crytek, published by Electronic Arts for Microsoft Windows, PlayStation 3.

  2. Run the following command to create the key file:

    openssl.exe genrsa -out <yourcertname>.key 4096

    Note: This command uses a 4096-bit length for the key. You should choose a bit length that is at least 2048 bits because communication encrypted with a shorter bit length is less secure. If a value is not provided, 512 bits is used.

Create a certificate signing request to send to a certificate authority

Use the key file you created in the procedure above to generate the certificate signing request (CSR). You send the CSR to a certificate authority (CA) to obtain a signed certificate.

Important: If you want to configure a SAN certificate to use SSL for multiple domains, first complete the steps in For SAN certificates: modify the OpenSSL configuration file below, and then return to here to generate a CSR.

  1. Run the following command to create a certificate signing request (CSR) file:

    openssl.exe req -new -key yourcertname.key -out yourcertname.csr

    If you did not set the OpenSSL configuration environment variable, OPENSSL_CONF, you might see either of the following messages:

    • An error message about the config information being unable to load. In this case, retype the command above with the following parameter: -config .confopenssl.cnf.

    • A warning that the /usr/local/ssl directory cannot be found. This directory does not exist on Windows, and you can simply ignore this message. The file is created successfully.

    To set an OpenSSL configuration environment variable, see Set the OpenSSL configuration environment variable (optional) section in this article.

  2. When prompted, enter the required information.

    Note: For Common Name, type the Tableau Server name. The Tableau Server name is the URL that will be used to reach the Tableau Server. For example, if you reach Tableau Server by typing tableau.example.com in the address bar of your browser, then tableau.example.com is the common name. If the common name does not resolve to the server name, errors will occur when a browser or Tableau Desktop tries to connect to Tableau Server.

Send the CSR to a certificate authority to obtain an SSL certificate

Send the CSR to a commercial certificate authority (CA) to request the digital certificate. For information, see the Wikipedia article Certificate authority and any related articles that help you decide which CA to use.

Use the key and certificate to configure Tableau Server

When you have both the key and the certificate from the CA, you can configure Tableau Server to use SSL. For the steps, see Configure External SSL.

For SAN certificates: modify the OpenSSL configuration file

Create Cer File

In a standard installation of OpenSSL, some features are not enabled by default. To use SSL with multiple domain names, before you generate the CSR, complete these steps to modify the openssl.cnf file.

Generate Cer File

  1. Open Windows Explorer and browse to the Apache conf folder for Tableau Server.

    For example: C:Program FilesTableauTableau Server<version_code>apacheconf

  2. Open openssl.cnf in a text editor, and find the following line: req_extensions = v3_req

    This line might be commented out with a hash sign (#) at the beginning of the line.

    If the line is commented out, uncomment it by removing the # and space characters from the beginning of the line.

  3. Move to the [ v3_req ] section of the file. The first few lines contain the following text:

    # Extensions to add to a certificate request
    basicConstraints = CA:FALSE
    keyUsage = nonRepudiation, digitalSignature, keyEncipherment

    After the keyUsage line, insert the following line:

    subjectAltName = @alt_names

    If you’re creating a self-signed SAN certificate, do the following to give the certificate permission to sign the certificate:

    1. Add the cRLSign and keyCertSign to the keyUsage line so it looks like the following: keyUsage = nonRepudiation, digitalSignature, keyEncipherment, cRLSign, keyCertSign

    2. After the keyUsage line, add the following line: subjectAltName = @alt_names

  4. In the [alt_names] section, provide the domain names you want to use with SSL.

    DNS.1 = [domain1]
    DNS.2 = [domain2]
    DNS.3 = [etc]

    The following image shows the results highlighted, with placeholder text that you would replace with your domain names.

  5. Save and close the file.

  6. Complete the steps in Create a certificate signing request to send to a certificate authority section, above.
