Navigate to your OpenSSL 'bin' directory and open a command prompt in the same location. Generate a CSR & Private Key: openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key. To generate a 4096-bit CSR you can replace the rsa:2048 syntax with rsa:4096 as shown below. Openssl req -out CSR.csr -new -newkey rsa:4096 -keyout privatekey.key. Online CSR and Key Generator. SSL.com’s public CSR and Key Generator is currently down for maintenance as part of our website’s redesign and update. We will be back soon with a new and updated version. In the mean time, we encourage our customers to learn about generating CSRs and keys in our customer portal’s CSR Manager. While Encrypting a File with a Password from the Command Line using OpenSSL is very useful in its own right, the real power of the OpenSSL library is its ability to support the use of public key cryptograph for encrypting or validating data in an unattended manner (where the password is not required to encrypt) is done with public keys. 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. The utility OpenSSL is used to generate both Private Key (key) and Certificate Signing request (CSR). OpenSSL is usually installed under /usr/local/ssl/bin.If you have a custom install, you will need to adjust these instructions appropriately. Feb 12, 2015  In this article, we will demonstrate how to create a CSR (Certificate Signing Request) on a Linux system. Creating a CSR – Certificate Signing Request in Linux To create a CSR, you need the OpenSSL command line utility installed on your system, otherwise, run the following command to install it. Sep 11, 2018  The first thing to do would be to generate a 2048-bit RSA key pair locally. This pair will contain both your private and public key. You can use Java key tool or some other tool, but we will be working with OpenSSL. To generate a public and private key with a certificate signing request (CSR), run the following OpenSSL command.

The following instructions will guide you through the CSR generation process on Nginx (OpenSSL). To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.

1. Log in to your server’s terminal.

You will want to log in via Secure Shell (SSH).

2. Enter CSR and Private Key command

Generate a private key and CSR by running the following command:

Here is the plain text version to copy and paste into your terminal:

Note:Replace “server ” with the domain name you intend to secure.

3. Enter your CSR details

Enter the following CSR details when prompted:

• Common Name: The FQDN (fully-qualified domain name) you want to secure with the certificate such as www.google.com, secure.website.org, *.domain.net, etc.
• Organization: The full legal name of your organization including the corporate identifier.
• Organization Unit (OU): Your department such as ‘Information Technology’ or ‘Website Security.’
• City or Locality: The locality or city where your organization is legally incorporated. Do not abbreviate.
• State or Province: The state or province where your organization is legally incorporated. Do not abbreviate.
• Country: The official two-letter country code (i.e. US, CH) where your organization is legally incorporated.

Note: You are not required to enter a password or passphrase. This optional field is for applying additional security to your key pair.

4. Generate the order

Locate and open the newly created CSR in a text editor such as Notepad and copy all the text including:

Note 1: Your CSR should be saved in the same user directory that you SSH into unless otherwise specified by you.

Note 2: We recommend saving or backing up your newly generate “.key ” file as this will be required later during the installation process.

Return to the Generation Form on our website and paste the entire CSR into the blank text box and continue with completing the generation process.

Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.

Generate random aes key online. After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Nginx using OpenSSL.

OpenSSL CSR Wizard

Our OpenSSL CSR Wizard is the fastest way to create your CSR for Apache (or any platform) using OpenSSL.
Fill in the details, click Generate, then paste your customized OpenSSL CSR command in to your terminal.

Note: After 2015, certificates for internal names will no longer be trusted.

After you've created a Certificate Signing Request (CSR) and ordered your certificate, you still need to install the SSL certificate on your server.
For instructions on how to install SSL certificates, see SSL Certificate Installation Instructions & Tutorials.

Where do I paste this command?

You can run this command wherever you have OpenSSL available—most likely on your server, but you can also run it on your own computer since macOS comes with OpenSSL installed. Just make sure you keep track of your private key file after you create your CSR; you'll need that private key to install your certificate.

What happens when I run this command?

OpenSSL creates both your private key and your certificate signing request, and saves them to two files: your_common_name.key, and your_common_name.csr. You can then copy the contents of the CSR file and paste it into the CSR text box in our order form.

What kind of certificate should I buy?

If you want an SSL certificate for Apache, your best options are Standard certificates and Wildcard certificates.

A DigiCert Wildcard can protect all server names on your domain (e.g., *.example.com,). Our unlimited server license lets you protect all your servers for just one price. Many of our customers save thousands of dollars per year by using a DigiCert Wildcard certificate.

Standard certificates are able to protect one server name (e.g., mail.example.com). If you only need SSL for one hostname, a Standard certificate will work perfectly.

What If I Need Subject Alternative Names?

Multi-Domain (SAN) certificates allow you to assign multiple host names—known as Subject Alternative Names or SANs—in one certificate.

Using OpenSSL to Add Subject Alternative Names to a CSR is a complicated task. Our advice is to skip the hassle, use your most important server name as the Common Name in the CSR, and then specify the other names during the order process. Our Multi-Domain (SAN) certificate ordering process allows you to specify all the names you need without making you include them in the CSR.
