WebApr 10, 2024 · Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions. WebJun 24, 2024 · Hashing involves using all the input data to get a specific output. 2. Algorithm. To get a hash value of a set length, an algorithm applies itself to an input. A hashing algorithm meets the same objectives to work. First, applying the same hash function to the same input data yields the same hash value.
