CompTIA Security+ SY0-701 Exam - Hashing Quiz

A hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size hash value, typically represented as a short string of characters. The hash function result, also known as a digest or checksum, provides a unique representation of the original data input. The functionality of hash functions relies on the fact that if there is any change to the data after the original hash was generated, the new hash value calculated after content modification will be different from the original result because hash functions are designed to be sensitive to changes in the input data.
