We support multiple subject alternative names, multiple common names, all x509 v3 extensions, RSA and elliptic curve cryptography private keys.
Java Keytool - Generate CSR
Java Keytool can be used to generate Java keystores, certificate signing requests (CSRs), convert certificate formats, and other certificate related functions. Keytool is bundled with Oracle's JDK. This article will walk through generating a CSR as well as generating a private key if one is not already available.
Sep 11, 2018 You apply by generating a CSR with a key pair on your server that would, ideally, hold the SSL certificate. The CSR contains crucial organization details which the CA verifies. Generate a CSR and key pair locally on your server. The key pair consists of a public and private key. Create a CSR (Certificate Signing Request) General CSR Creation Guidelines Before you can order an SSL certificate, it is recommended that you generate a Certificate Signing Request (CSR). 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: Set the OpenSSL configuration environment variable (optional). Generate a key file. Create a Certificate Signing Request (CSR). How to generate a CSR using an F5 BIG-IP Loadbalancer (version 9) Launch the F5 BIGIP web GUI. Under Local Traffic select 'SSL Certificates' then 'Create.' Under General Properties give your certificate a name (this name will be used in the future to identify this certificate).
1. Generate a keystore:
A keypair must first exist in order to generate a CSR. If you have an existing Java keystore, proceed to the next step, otherwise use the command below to generate a new Java keystore:
keytool -genkey -alias mydomain -keyalg RSA -keystore KeyStore.jks -keysize 2048
Enter keystore password: <create keystore password>
Re-Enter new password: <confirm keystore password>
You now have a Java keystore from which you can generate a CSR.
Note: You can change the Alias of mydomain to a word of your choosing. This alias must remain the same for key generation, CSR generation, and signed public key importing.
2. Generate a CSR:
keytool -certreq -alias mydomain -keystore KeyStore.jks -file mydomain.csr
Answer each question when prompted.
Use the chart below to guide you through the process:
Field | Example |
---|---|
First & Last Name | Domain Name for SSL Certificates Entity Name for Code Signing |
Organizational Unit | Support (Optional, e.g. a department) |
Organization | GMO GlobalSign Inc (Entity's Legal Name) |
City / Locality | Portsmouth (Full City name) |
State / Province | New Hampshire (Full State Name) |
Country Code | US (2 Letter Code) |
Confirm or reject the details by typing 'Yes' or 'No' and pressing Enter
Press Enter to use the same password as the keystore, alternatively specify a separate password and press enter.
You should now have a file called mydomain.csr which can be used to request a digital certificate from GlobalSign.
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.
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).
