how to change signature [SHA1:] in the XDK?

[Marco_Antonio_F_]

Hello!
I decided to update an old application made in other compiler and have no more signing or signing key [SHA1: HAsisa783nms ... something like that].
I wonder how I add the old key that google me when I try to add the new app instead of new?
It is possible? And if so where in the XDK can make this trade?
Thank you !!!

You need to get your keystore that was used to originally sign your app and send that you html5tools@intel.com

Please include the XDK email address that you want the keystore associated with.
