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.

Generate 4096 bit RSA Keys. The difference is RSA, by default, uses a 2048 bit key and canbe up to 4096 bits, while DSA keys must be exactly 1024 bits as specified by FIPS 186-2. It is recommended to use a 4096 bit key as a matter of habit in today’s world where personal and private digital security is often in question, never view. Example: SSL Certificate - Generate a Key and CSR. Version: 2020.1. Openssl.exe genrsa -out.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. As you can see, doubling the certificate key size places an enormous additional burden on the server's CPU and is many times slower. Avoid 4096 bit keys unless you have a specific threat model which requires their use. I decided to run openssl speed with three key sizes: 1024, 2048 and 4096 bits. 4096-bit key provided as an option during server key generation on JSCAPE MFT Server v10.2. Well, there could be a couple of reasons. One is simply to make the application future proof. A future proof security solution can mitigate the risk of cyber threats. We know that cyber criminals are always one step ahead of security professionals, so we're not 100% sure 2048-bit keys are.

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.

Last time I used 2048 bit key and it took about an hour. Now I'm trying with a 4096 bit key and it's been more than a day. In fact it's been another 12 hours since I reinitiated all my settings, enabled the build-it hardware random number generator and tried again. If you have a 4096 bit SSL certificate, in order to support some clients (especially Java-based clients and some older clients) you will want to generate a 2048 bit or 1024 bit Diffie-Hellman Key and add it to your server certificate. However, if you support a 1024 bit DH key you should also be aware of the Logjam attack. You can accommodate these clients easily by adding a DH key of the appropriate size, but first carefully consider which clients you want to support. Sep 22, 2015  So if you create a key using the integrated tool (Kleopatra) for example you will always get max. A 2048 key which is still secury but not the possible maximum. If you want to create a 4096 key you need to use the cmd in Windows. So here is a tutorial to do it Start the command prompt: Start.

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

Windows 8 media center product key generator. To configure Tableau Server to use SSL, you must have an SSL certificate. To obtain the SSL certificate, complete the steps:

2. Generate a key file.
3. Create a Certificate Signing Request (CSR).
4. Send the CSR to a certificate authority (CA) to obtain an SSL certificate.
5. 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

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). /macx-video-converter-pro-key-generator.html.

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. Download game play boy ps2.

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.

Openssl Generate Key

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.
