Generate CSR - OpenSSL Introduction. This article provides step-by-step instructions for generating a Certificate Signing Request (CSR) in OpenSSL. This is most commonly required for web servers such as Apache HTTP Server and NGINX. If this is not the solution you are looking for, please search for your solution in the search bar above. Mar 01, 2016  Use the following command to create a CSR using your newly generated private key: openssl req -new -key yourdomain.key -out yourdomain.csr. After entering the command, you will be asked series of questions. Your answers to these questions will be embedded in the CSR. Answer the questions as described below.

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.

Mar 30, 2015  You will also be prompted for information to populate the CSR. At the command line, type: $ openssl req -new -key /path/to/wwwservercom.key -out /path/to/wwwservercom.csr. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in.

You will also be prompted for information to populate the CSR. At the command line, type: $ openssl req -new -key /path/to/wwwservercom.key -out /path/to/wwwservercom.csr. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in. One of the most versatile SSL tools is OpenSSL which is an open source implementation of the SSL protocol. There are versions of OpenSSL for nearly every platform, including Windows, Linux, and Mac OS X. OpenSSL is commonly used to create the CSR and private key for many different platforms, including Apache. However, it also has hundreds of different functions that allow you to view the.

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.

Configure a certificate for multiple domain names

Generate

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

  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

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.

  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.

OpenSSL Commands and SSL Keytool List

OpenSSL is an open-source implementation of SSL/TLS protocols and is considered to be one of the most versatile SSL tools. It’s a library written in C programming language that implements the basic cryptographic functions. OpenSSL has different versions for most Unix-like operating systems, which include Mac OC X, Linux, and Microsoft Windows etc.

Open SSL is normally used to generate a Certificate Signing Request (CSR) and private key for different platforms. However, it also has several different functions, which can be listed as follows. It is used to:

  • View details about a CSR or a certificate
  • Compare MD5 hash of a certificate and private key to ensure they match
  • Verify proper installation of the certificate on a website
  • Convert the certificate format

Most of the functions mentioned below can also be performed without involving OpenSSL by using these convenient SSL tools. Here, we have put together few of the most common OpenSSL commands.

General OpenSSL Commands

These are the set of commands that allow the users to generate CSRs, Certificates, Private Keys and many other miscellaneous tasks. Here, we have listed few such commands:

(1) Generate a Certificate Signing Request (CSR) and new private key

(2) Generate a self-signed certificate

(3) Create CSR based on an existing private key

(4) Create CSR based on an existing certificate

(5) Passphrase removal from a private key

SSL Check Commands

Openssl Command To Generate Key And Certificate

These commands are very helpful if the user wants to check the information within an SSL certificate, a Private Key, and CSR. Few online tools can also help you check CSRs and check SSL certificates.

(1) Certificate Signing Request (CSR)

(2) Private Key

(3) SSL Certificate

(4) PKCS#12 File (.pfx or .p12)

Convert Commands

As per the title, these commands help convert the certificates and keys into different formats to impart them the compatibility with specific servers types. For example, a PEM file, compatible with Apache server, can be converted to PFX (PKCS#12), after which it would be possible for it to work with Tomcat or IIS. However, you can also use the SSL Converter to change the format, without having to involve OpenSSL.

(1) Convert DER Files (.crt, .cer, .der) to PEM

(2) Convert PEM to DER

(3) Convert PKCS #12 File (.pfx, .p12) Containing a Private Key and Certificate to PEM

To output only the private key, users can add –nocerts or –nokeys to output only the certificates.

(4) Convert PEM Certificate (File and a Private Key) to PKCS # 12 (.pfx #12)

Debugging Using OpenSSL Commands

If there are error messages popping up about your private key not matching the certificate or that the newly-installed certificate is not trusted, you can rely on one of the comments mentioned below. You can also use the SSL certificate checker tool for verifying the correct installation of an SSL certificate.

(1) Check SSL Connection (All certificates, including Intermediates, are to be displayed)

Here, all the certificates should be displayed, including the Intermediates as well.

(2) Check MD5 Hash of Public Key

This is to ensure that the public key matches with the CSR or the private key.

SSL Keytool List

Java Keytool is a key and certificate management utility that allows the users to cache the certificate and manage their own private or public key pairs and certificates. Java Keytool stores all the keys and certificates in a ‘Keystore’, which is, by default, implemented as a file. It contains private keys and certificates that are essential for establishing the reliability of the primary certificate and completing a chain of trust.

Every certificate in Java Keystore has a unique pseudonym/alias. For creating a ‘Java Keystore’, you need to first create the .jks file containing only the private key in the beginning. After that, you need to generate a Certificate Signing Request (CSR) and generate a certificate from it. After this, import the certificate to the Keystore including any root certificates.

The ‘Java Keytool’ basically contains several other functions that help the users export a certificate or to view the certificate details or the list of certificates in Keystore.

Here are few important Java Keytool commands:

For Creating and Importing

These Keytool commands allow users to create a new Java Keytool keysKeystore, generate a Certificate Signing Request (CSR) and import certificates. Before you import the primary certificate for your domain, you need to first import any root or intermediate certificates.

Generate

(1) Import a root or intermediate CA certificate to an existing Java keystore

(2) Import a signed primary certificate to an existing Java keystore

(3) Generate a keystore and self-signed certificate

(4) Generate Key Pair & Java Keystore

(5) Generate CSR for existing Java Keystore

For Checking

Users can check the information within a certificate or Java keystore by using the following commands:

(1) Check an individual certificate

(2) Check certificates in Java keystore

(3) Check specific keystore entry using an alias

Other Java Keytool Commands

(1) Delete a certificate from Java Keystore keystore

(2) Change the password in Java keystore / Change a Java keystore password
