CSR stands for ‘Certificate Signing Request’, that is generated on the server where the certificate will be used on. A CSR contains information about to your organization and domain name, locality, and country and a public key that will be included in your certificate.
Create CSR, csr, Generate CSR, ssl csr, ssl key CSR stands for ‘ Certificate Signing Request ’, that is generated on the server where the certificate will be used on. A CSR contains information about to your organization and domain name, locality, and country and a public key that will be. Complete the following steps to create your CSR. Before you can create your CSR, you need to create your Java keystore. Your Java keystore contains your private key. Run the following command to create your 2048 bit Java keystore: keytool -genkey -alias myalias -keyalg RSA –keysize 2048 -keystore c: yoursite.keystore 2. Generate or import the private key and certificate for a Linux web server's SSL/TLS offload with AWS CloudHSM. You can then use the private key to create a certificate signing request (CSR). Use the CSR to create the SSL/TLS certificate. To generate a private key on an HSM.
This article has 3 methods to create CSR (Certificate Signing Request) on Linux systems. You can choose any one of below methods. All methods will do the same task, only they have a detailed explanation.
Method 1 – Using Single Command
We can create CSR using the single command like below. But make sure you have installed OpenSSL package on your system. The below command will first create a private key and then generate CSR. This command will also require few details as input.
Method 2 – Short Instructions
Below are three simple commands to generate CSR. You may also use detailed instructions to do it.
Method 3 – Detailed Instructions
Step 1: Install Required Packages.
In order to generate CSR, you required OpenSSL to be installed on your system. If it is not already installed use below command to install it.
Step 2: Generate Key for your Domain.
Firstly you required root access to generate a key file. So login as root and use below command to generate a key.
Sample output:
At the end of the command, it showing 2048, which is the length of the key in bits. Most of CA required 2048 bit length keys. Above command will create a key file tecadmin.net.key, which is used in step 3.
Step 3: Generate CSR for your Domain using Key.
After generating a key, next steps are to generate CSR for the domain. Use below command to generate CSR file, This command will prompt for your organization and common name, locality, email, and country. Common Name must be the same as your domain name.
Sample Output:
Above command will generate a file tecadmin.net.csr in the current directory, Use this file to order your SSL from CA (Certificate Authority).

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.
Generate Private Key From Csr Linux Server
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.
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.
