WebJul 26, 2024 · A cryptographic hash function (CHF) is an algorithm that can be run on data such as an individual file or a password to produce a value called a checksum. The main use of a CHF is to verify the authenticity of a piece of data. WebThe most commonly used method for hashing is known as modular hashing, which involves mapping a key k into one of the m slots by taking the remainder of k divided by m. This can be represented by the hash function h (k) = k mod m. For example, if the hash table has size m = 12 and the key is k = 100, then h (k) = 4.
