Where is the default trusted certificate keystore file located on my Windows system? I think I have Java 7 installed.

If you have Java installed on your Windows system, you can find the default trusted certificate keystore file in the $JAVA_HOME folder, which is normally at "\Program Files\java\jre7\lib\security".

The default trusted certificate keystore file is named as "cacerts" as shown in the example below:

C:\Users\fyicenter>dir "\Program Files\java\jre7\lib\security"

 Directory of C:\Program Files\java\jre7\lib\security

Not that the default installation of JDK or JRE provides the "cacerts" trusted keystore file, not the "jssecacerts".
