In hash tables, since hash collisions are inevitable, hash tables have mechanisms of dealing with them, known as collision resolutions. Two of the most common strategies are open addressing and separate chaining. The cache-conscious collision resolution is another strategy that has been discussed in the past for string hash tables.

This property is sometimes referred to as weak collision resistance. Functions that lack this property are vulnerable to second pre-image attacks. Collision resistance: it should be hard to find two different messages m 1 and m 2 such that hash(m 1) = hash(m 2). Such a pair is called a (cryptographic) hash collision.
Thus, if two strings have the same digest, one can be very confident that they are identical. Second pre-image resistance prevents an attacker from crafting a document with the same hash as a document the attacker cannot control. Collision resistance prevents an attacker from creating two distinct documents with the same hash.
