In hash tables, you store data in forms of key and value pairs. The key, which is used to identify the data, is given as an input to the hashing function. The hash code, which is an integer, is then mapped to the fixed size we have.

The cryptographic strength of the HMAC depends upon the size of the secret key that is used and the security of the underlying hash function used. It has been proven that the security of an HMAC construction is directly related to security properties of the hash function used. The most common attack against HMACs is brute force to uncover the secret key. HMACs are substantially less affected by collisions than their underlying hashing algorithms alone. In particular, Mihir Bellare … WebApr 13, 2024 · Learn more.
