Self signed keystore can be easily created with keytool command. But if you have a private key and a CA signed certificate of it, You can not create a key store with just one keytool command. You need to go through following to get it done. Create PKCS 12 file using your private key and CA signed certificate of it. You can use openssl. Apr 27, 2016 Scenario You have generated a self signed certificate or a client gives you a certificate with a private key that was signed by the client's signing authority. You want to create a new Java keystore using your new private key or the client's existing private key. Command First you need. 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. Jul 01, 2019 How to query and verify your keystores with the keytool command. Create private key and keystore. To get started, the first thing we need to do is create a private key keystore. This is going to be a file on your filesystem, and I'm going to name mine privateKey.store. To create this “private key keystore,” run the following keytool command. 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. Dec 31, 2018.

To Generate a Certificate by Using keytool
By default, the keytool utility creates a keystorefile in the directory where the utility is run.
Before You Begin
To run the keytool utility, your shell environmentmust be configured so that the J2SE /bin directory is inthe path, otherwise the full path to the utility must be present on the commandline.
- Change to the directory that contains the keystore and truststorefiles.Always generate the certificate in the directory containingthe keystore and truststore files. The default is domain-dir/config.
- Generate the certificate in the keystore file, keystore.jks,using the following command format:Use any unique name as your keyAlias. Ifyou have changed the keystore or private key password from the default (changeit), substitute the new password for changeit.The default key password alias is s1as.A prompt appears that asks for your name, organization, and other information.
- Export the generated certificate to the server.cer file(or client.cer if you prefer), using the following commandformat:
- If a certificate signed by a certificate authority is required,see To Sign a Certificate by Using keytool.
- Create the cacerts.jks truststore file andadd the certificate to the truststore, using the following command format:If you have changed the keystore or private key password from the default(changeit), substitute the new password.Information about the certificate is displayed and a prompt appearsasking if you want to trust the certificate.
- Type yes, then press Enter.Informationsimilar to the following is displayed:
- To apply your changes, restart GlassFish Server. See To Restart a Domain.

Certificate Signing Request (CSR) Help
Using Java Keytool
For Oracle Weblogic
There is a video for this solution.
Complete the following steps to create your CSR.
1. 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. Note the alias you use here to create the keystore. You will need to use the same alias later when you install your certificate.
Please note: the below example applies to Entrust Certificate Services customers with the intended purpose of using an SSL/TLS certificate purchased from Entrust Datacard.
3. You will be prompted to enter your DN information for your CSR. When it asks for your first and last name, make sure you enter the FQDN of your site. Here is an example:
What is your first and last name?
[Unknown]: http://www.entrust.com/
What is the name of your organizational unit?
[Unknown]: IT
What is the name of your organization?
[Unknown]: Entrust Inc
What is the name of your City or Locality?
[Unknown]: Ottawa
What is the name of your State or Province?
[Unknown]: Ontario
What is the two-letter country code for this unit?
[Unknown]: CA
Is CN=www.entrust.com, OU=IT, O=Entrust Inc, L=Ottawa, ST=Ontario, C=CA correct?
[no]: yes
4. To create your CSR, run the following command:
keytool -certreq -keyalg RSA -alias myalias -file certreq.txt -keystore c:yoursite.mykeystore
5. To find your CSR, enter the command:
type certreq.txt
Your SSL/TLS Certificate should now be installed. If you have any questions or concerns please contact the Entrust Certificate Services Support department for further assistance.
