relate to my question.

You suffer from a failure of the imagination. The preceding item does relate to your question. It's the complementary action to the one you requested. Compute the list of unique keys and all your keys not on that list are the ones common to your two hashes. Alternatively, modify the algorithm to keep the keys that don't satisfy the uniqueness criterion and you have the list of keys you want.

If that's not obvious, you might want to reconsider your career choices...or at least refrain from posting snotty replies to any assistance you are given.
