You title suggest you have a key, and want a value, but your question is actually the other way around.

The answer is that if you want to find a key belonging to a certain value, you should have used a different datastructure. In a hash, keys are unique, values don't have to. The entire point of a hash is to be able to search with keys - if you want to search with the values, you should have used the values as the keys, and the keys as the values.
