Please note that Keytool is a java application and you will need to confirm that is installed on your machine. If not you will need to install a java version that has keytool, either jre or jdk. Once you have confirmed that a jdk is installed, please go to the search bar and type in – cmd. This will bring up the command line prompt, and then execute the script as defined below. NOTE you will have to use OpenSSL or a similar tool to create the PKCS12 documents if that has not been created by another person.
