You will need to break the file you got from the CA into two parts, one containing the certificate block called 'certificate.txt' and and one containing the private key block called 'key.txt': openssl pkcs12 -export -out mycertkey.p12 -in certificate.txt -inkey key.txt Once you have the PKCS#12 format file you can import it into Windows. Jun 09, 2019 This article describes how to recover a private key after you use the Certificates Microsoft Management Console (MMC) snap-in to delete the original certificate in Internet Information Services (IIS). You delete the original certificate from the personal folder in the local computer's certificate store. I have code signing certificate, from them i got a X.cer file only. When i need to sign my.exe i need a PFX file for that i need two files A.key and B.crt Q. How do i make from X.cer file, A.key. A certificate.crt and privateKey.key can be extracted from your Personal Information Exchange file (certificate.pfx) using OpenSSL. Follow this article to create a certificate.crt and privateKey.key files from a certificate.pfx file.

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

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