To Use keytool to Create a ServerCertificate
Run keytool to generate a new key pair in the defaultdevelopment keystore file, keystore.jks. This exampleuses the alias server-alias to generate a new public/privatekey pair and wrap the public key into a self-signed certificate inside keystore.jks. The key pair is generated by using an algorithm oftype RSA, with a default password of changeit. For moreinformation and other examples of creating and managing keystore files, readthe keytool online help at http://download.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html.
The Java Keytool is a command line tool which can generate public key / private key pairs and store them in a Java KeyStore.The Keytool executable is distributed with the Java SDK (or JRE), so if you have an SDK installed you will also have the Keytool executable. Jan 25, 2018 Java keytool genkey FAQ: Can you share some examples of the Java keytool genkey command, and the genkey process? In my previous article on the Java keytool command, keystore files, and certificates, I demonstrated how to generate a private key with the keytool genkey option, but to simplify things a little, I thought I'd demonstrate the keytool/genkey command again here by itself.
Note –Java Keystore Generate Aes Key
RSA is public-key encryption technology developed by RSA DataSecurity, Inc.
From the directory in which you want to create the key pair, run keytool as shown in the following steps. /visual-studio-2012-product-key-generator.html.
Java Keystore Example
Generate the server certificate.
Type the keytool command all on one line:
When you press Enter, keytool prompts you to enterthe server name, organizational unit, organization, locality, state, and countrycode.
You must type the server name in response to keytool’sfirst prompt, in which it asks for first and last names. For testing purposes,this can be localhost.
When you run the example applications, the host (server name) specifiedin the keystore must match the host identified in the javaee.server.name property specified in the file tut-install/examples/bp-project/build.properties.
Export the generated server certificate in keystore.jks intothe file server.cer.
Type the keytool commandall on one line:
If you want to have the certificate signed by a CA, read the exampleat http://download.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html.
To add the server certificate to the truststore file, cacerts.jks, run keytool from the directory where you createdthe keystore and server certificate.
Use the following parameters:
Information on the certificate, such as that shown next, will appear:
Type yes, then press the Enter or Return key.
The following information appears:

To Create a CSR with keytool and Generate a SignedCertificate for the Certificate Signing Request
Java Aes Encryption Example
Perform the following operations from the command line.
Generate the Certificate Signing Request.
Generate a signed certificate for the associated Certificate SigningRequest.
Use the keytool to import the CA certificate into the client keystore.
Use the keytool to import the signed certificate for the associatedclient alias in the keystore.
Caution –The following error will be generated if there is no certificatechain in the client certificate.
This error is because the CA’s certificate was not imported intothe KeyStore first. You must import theCA's certificate (step 4), then import the client.cer file itself to forma certificate chain (step 5).
Now that we have a private key and an associating certificate chainin the KeyStore clientkeystore, we canuse it as a KeyStore for client (adapter)authentication. The only warning is that the CA certificate must be importedinto the trusted certificate store of the web server to which you will beconnecting. Moreover, the web server must be configured for client authentication(httpd.conf for Apache, for example).
