Its where you put your house key or car keys. Kinda like a "hida key" only on your BB

To "Store Keys"

(couldn't resist)

I think it's like a trusted web site key. It's security related.

Key stores is a storage location that is used in conjunction with digital encription and digital certificates that are required for access to certain secure websites and networks. I'm not sure what the relation is though. It's probably one of those situations where if you need to ask, you don't really need to know. If you need it, someone will tell you and you can ask them for details.

Hope this helps.
