Java Keytool - Generate CSR

Mar 10, 2018  Using 'keytool export' to create a certificate file Assuming we have a Java keystore file that contains a private key (as demonstrated in this ' keytool genkey private key example ') that we want to export to a certificate file, and we know the password for the private key keystore, this process is. Apr 23, 2012 Generating a RSA Key with the Java Keytool Use the Java keytool to create public and private keys for RSA authentication if the client is in Java. RSA authentication uses public and private keys instead of passwords to authenticate with the ESP Server.

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.

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:

Mar 03, 2020  openssl genpkey -algorithm RSA -out rsaprivate.pem -pkeyopt rsakeygenbits:2048 openssl rsa -in rsaprivate.pem -pubout -out rsapublic.pem. These commands create the following public/private key pair: rsaprivate.pem: The private key that must be securely stored on the device and used to sign the authentication JWT. The Commands to Run Generate a 2048 bit RSA Key. That generates a 2048-bit RSA key pair. Export the RSA Public Key to a File. The -pubout flag is really important. Be sure to include it. Do Not Run This, it Exports the Private Key. Visually Inspect Your Key Files. It is important to visually. RSA keys must be between 2048 and 4096 bits. To generate a new public/private key pair in a Java keystore Use the -genkeypair option to generate a key and save it to a Java keystore (newkeystore.jks in this example). The example shown here prompts you to enter values for items that make up the distinguished name (DN) in the certificate. This document describes how I generate 2048-bit RSA keys. Here is the log to generate signature key and encryption subkey. I invoke GnuPG with -gen-key option. Generating a Public/Private Key Pair You need to programmatically create a public/private key pair using the RSA algorithm with a minimum key strength of 2048 bits. The method you use to generate this key pair may differ depending on platform and programming language. Generating a public/private key pair by using OpenSSL library.

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.

Introduction

This article covers the creation of a new Java keystore using Java keytool.

Process

You can watch the video below for a tutorial.

Or, you can check the step by step guidelines below.
1. Create a new keystore:
Open a command prompt in the same directory as Java keytool; alternatively, you may specify the full path of keytool in your command. Pay close attention to the alias you specify in this command as it will be needed later on.
keytool -genkey -alias mydomain -keyalg RSA -keystore KeyStore.jks -keysize 2048
2. Generate a CSR based on the new keystore:
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:

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 order or reissue a digital certificate from GlobalSign.
3. While the order processes, download the root & intermediate certificates for your order. You can identify the correct root & intermediate certificate based on hash algorithm and product type.
4. Import the root & intermediate certificates into your keystore. Import the root certificate first, followed by the intermediate. Make sure you specify the correct alias of 'root' and 'intermediate' respectively.
keytool -import -trustcacerts -alias root -file root.crt -keystore KeyStore.jks
keytool -import -trustcacerts -alias intermediate -file intermediate.crt -keystore KeyStore.jks
5. Download & import your new certificate
Download your new certificate; save it as mydomain.crt.
Use the same alias as the private key so it associates them together. The alias here must match the alias of the private key in the first command.
keytool -import -trustcacerts -alias mydomain -file mydomain.crt -keystore KeyStore.jks
The keystore is now complete and can be used for signing code or deploying on a Java based web server depending on the product you ordered.
