• If you simply don't know where your private key is, then it will be located somewhere on the computer on which you generated the CSR. Most instructions for generating a CSR involve generating a private key and a CSR that is based on the private key, saving the private key on your filesystem somewhere. Share improve this answer.

Just fill in the details, click Generate, and paste your customized keytool command into your terminal. If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below: Create a New Keystore. You will be using the keytool command to create your new key.

How to generate a CSR using Java Keytool

**NOTE: You must generate a new keystore through this process. If you try to install a new certificate to an old keystore your certificate will not work properly. Backup and remove any old keystores if necessary before beginning this process.

Recommended: Save yourself some time by using our new Java Keytool CSR Wizard to create your CSR with Keytool. Just fill in the details, click Generate, and paste your customized keytool command into your terminal.

If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below:

Create a New Keystore

1. You will be using the keytool command to create your new key-CSR pairing. Enter the following:

   keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore yourdomain.jks

   'Yourdomain' is the name of the domain you are securing. However, if you are ordering a Wildcard Certificate, do not include * in the beginning of the filename as this is not a valid filename character.

2. You will be prompted for the DN information. Please note: when it asks for first and last name, this is not YOUR first and last name, but rather your domain name and extension(i.e., www.yourdomain.com). If you are ordering a Wildcard Certificate this must begin with *. (example: *.digicert.com)

3. Confirm that the information is correct by entering 'y' or 'yes' when prompted. Next you will be asked for your password to confirm. Make sure to remember the password you choose.

Generate Your CSR with Your New keystore

1. Next, use keytool to actually create the Certificate Signing Request. Enter the following:

   keytool -certreq -alias server -keyalg RSA -file yourdomain.csr -keystore yourdomain.jks

   Again, 'yourdomain' is the name of the domain you are securing. (without the * character if you are ordering a Wildcard Certificate).

2. Enter the keystore password.

3. Then the SSL Certificate CSR file is created. Open the CSR with a text editor, and copy and paste the text (including the BEGIN and END tags) into the DigiCert web order form.

4. After you receive your SSL Certificate from DigiCert, you can install it.

Generating a CSR for Issuance of an SSL Certificate with Keytool

How to generate a Certificate Signing Request for your Java Web Server

SSL Certificates have become an essential requirement for any live website. SSL certificates are verified and issued by a Certificate Authority (CA). These certificates have two categories:

• Self-Signed certificates: Signed by an entity creating it rather than a trusted certificate authority. Mostly used for trial and development purposes and on an intranet environment.
• CA Certificates: Signed by a trusted CA (Certificate Authority) such as Verisign, DigiCert, GoDaddy,Thawte, etc.

The first step towards acquiring an SSL certificate is generating a CSR and submitting it to the CA. A CSR or certificate signing request is a block of encrypted text sent from an entity to a certificate authority when applying for SSL certificate. It contains all the information including the organization’s name, country, city, email address, etc. that is required for the generation of an SSL certificate.

In this article, I will demonstrate to you how to generate CSR on Ubuntu 18.04 LTS.

Special symbols generator. For generating CSR on Ubuntu OS, you will require OpenSSL tool. OpenSSL is an open source tool widely used for generating a CSR. To check whether OpenSSL is installed or not, open the Terminal by pressing Ctrl+Alt+T and then type the below command:

If it is already installed, it will return the following results.

Installing OpenSSL

If you don’t see the above results, enter the below command in order to install OpenSSL.

Generating a CSR with OpenSSL

There are two steps involved in generating a certificate signing request (CSR). First, you have to generate a private key, and then generate CSR using that private key.

Step 1: Generate a private key

Enter the following command in the Terminal with sudo to generate a private key using RSA algorithm with a key length of 2048 bits.

Replace domain with your own domain name.

Above command will generate a private key named domain.key and place it in your current directory.

Step 2: Generate the CSR

After generating the private key, you will need to generate CSR. Enter the below command to generate CSR using the newly generated private key.

You will be prompted to enter a few details like Country name, State, Organization name, email address, etc. Make sure to enter the right information, as it will be checked by a certificate authority.

This command will generate a CSR file named domain.csr and put it in your current directory.

Alternative Method of generating a CSR

Alternatively, there is a single command that will create a private key and then generate CSR simultaneously. The command syntax is as follows:

Replace domain in the above command with your own domain.

Enter few details like Country name; State, Organization name, email address, etc. and make sure to enter right information as it will be later checked by a certificate authority.

Above command will generate a private key and CSR named domain.key and domain.csr respectively and put it in your current directory.

View and copy the content of a private key

You can view and keep the private keys on your server that you may need later. However, do not share it with anyone. To view the contents of the private key file, navigate to the directory where the key file is stored. Then run the below method as sudo:

To copy the contents of the private key file, select and copy the entire content including the “BEGIN PRIVATE KEY” and “END PRIVATE KEY” tags.

View and copy contents of CSR file

You will need to send the CSR file to a certificate signing authority by copy-pasting the entire content of CSR file to certificate authority.

Generate random key of letters. Since the writer doesn'tknow which words will appear, creativity must be used to successfully incorporate all the words.

To view the content of the CSR file, navigate to the directory where the CSR file is stored. Then run the below method as sudo:

To copy the contents of the CSR file, select and copy the entire content including the “BEGIN CERTIFICATE REQUEST” and “END CERTIFICATE REQUEST” tags.

That was all you need to know about generating a certificate signing request (CSR). Now you can get an SSL certificate from certificate signing authority by pasting the content of CSR file on the order form when enrolling for SSL certificate.
