WebOct 22, 2024 · How it works? As we discussed, a hash function lies at the heart of a hashing algorithm. But, to get the hash value of a pre-set length, you first need to divide the input data into fixed sized blocks. This is because a hash function takes in data at a fixed-length. These blocks are called ‘data blocks.’ This is demonstrated in the image below. WebHashing can also be used when analyzing or preventing file tampering.
