How to generate key or jks file using java keytool command

• First open a command prompt (if using Windows, open the command prompt as an administrator) and navigate to your <JDK_HOME>\bin directory. Once there, generate the key store and private key using the command below.

keytool -genkey -alias <store name> -keyalg RSA -keysize 2048 -sigalg MD5withRSA -keypass <password> -keystore <store name>.jks -storepass <password>





Where <store name> is the name of the key store you want to use, <password> is the password you wish to use. You will be prompted to enter some additional information like below.

This command will generate blank jks file in your <JDK_HOME>\bin directory.
