To Use keytool to Create a Server Certificate. Run keytool to generate a new key pair in the default development keystore file, keystore.jks. This example uses the alias server-alias to generate a new public/private key pair and wrap the public key into a self-signed certificate inside keystore.jks. The key pair is generated by using an algorithm of type RSA, with a default password of changeit. How to generate.key and.crt file from JKS file for httpd apache server.

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. 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.
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
Keytool Create Csr With Private Key
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.

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.
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.
Keytool Generate Certificate From Private Key Mac
2. Generate a CSR:
Keytool Import Private Key
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.
