How do I open a Java Keystore?

If you cannot open your JKS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JKS file directly in the browser: Just drag the file onto this browser window and drop it.

Yes you can, provided that it is in a format Java Keytool understands (jks,p12) and you have the password to operate on it.

The usual extension is .jks but it's not mandatory. You only have to try. Use

keytool -list -keystore [KEYSTORE_PATH_HERE]

to explore it.

Add "-v" for verbose output of the content (keys and certificates). If it's not a real Java keystore you will see an exception telling you this, otherwise it will ask for a password and if correct, it will "open" it.

This is very basic since there are many options (for example multiple password for different 'owners'). Btw, since Keytool is part of the JDK/JRE standard tools, this works on other OSes too.
