WebDouble Hashing. Double hashing is a computer programming technique used in conjunction with open addressing in hash tables to resolve hash collisions, by using a secondary hash of the key as an offset when a collision occurs. Double hashing uses the idea of applying a second hash function to key when a collision occurs.
