Solution

Where did you get your keystore.p12 file? This post seems to indicate that there's an error in the format of the file, and has some suggestions on how to address it.

Specifically, it indicates to check and make sure there are no [leading or trailing] spaces in the file.

Are you sure its properly formatted?
