How to generate a Certificate Signing Request (CSR) via Java Keystore

A CSR is encoded text that contains information about the certificate requester. This information includes, but is not limited to, the publisher name for the certificate (referred to as a "Common Name"), organization name (if applicable), and a contact email for the certificate. When creating a CSR it will export two files, these two files will be your CSR, which will be requested during enrollment, and a corresponding private key which should not be shared and will be required during installation.

Note: Before proceeding with the instructions below, confirm the Java Development Kit (JDK) is installed correctly on your server or local computer.

CSR Generation Instructions

  1. To make a keystore and key file, run the command prompt below:

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

  1. Enter the required information, when prompted:
    • Enter keystore password:
    • Re-enter new password:
    • What is your first and last name?
    • What is the name of your organization unit?
    • What is the name of your organization?
    • What is the name of your City or Locality?
    • What is the name of your State or Province?
    • What is the two-letter country code for this unit?
    • Is CN = CompanyName or Firstname Lastname, OU=DeparmentName, O=CompanyName, L=City, ST=State, C=CountryCode correct?
    • Enter key password for <server>:
  2. The above command will create a Java keystore file called keystore.jks
  3. To make the CSR from the keystore, run the command prompt below:

keytool -certreq -alias server -file csr.csr -keystore keystore.jks
Enter keystore password:

Note: The keystore password is the same password you created in step 2.

  1. The above command will create the CSR and private key and saves as a .csr file and a .jks file.
  2. Copy the newly generated CSR and include the header -----BEGIN NEW CERTIFICATE REQUEST---- and footer -----END NEW CERTIFICATE REQUEST----- tags.
