I developed an app some 2 or 3 years ago using the now apparently defunct Motodev Studio. I saved the keystore file, but the java keytool does not seem to recognize the file:
>keystore -list -keystore motodev.keystore
returns
keytool error: java.io.IOException: Invalid keystore format
It would be really nice to be able to use this keystore, since I have literally tens of thousands of current installs on the app it controls.
