Data hashing definition
WebThe idea of a hash table is more generalized and can be described as follows. The concept of a hash table is a generalized idea of an array where key does not have to be an integer. We can have a name as a key, or for that matter any object as the key. The trick is to find a hash function to compute an index so that an object can be stored at a WebMay 8, 2024 · INTERPRETATION: Data hashing is done by using a hash function, which converts a field into a condensed fixed-value representation, the so called hash value. For data security applications this requires that the hash function is collision-resistant, which means that it is very hard to find data that will generate the same hash value.
