For this recipe, we will use the Java keytool utility, so make sure you have the following configuration set up:

• Obtain the required SSL certificate from the target system.
• Ensure that the JAVA_HOME environment variable is set properly.
• Make sure you know which JDK/JRE Jira is using. You can find this information on the System Info page, where you need to look for the java.home property.
• Make sure your JRE/JDK's bin directory is added to your PATH environment variable, and the keytool command will output its usage.
• Obtain the password for the Java trust store used by Jira.
