WebJun 23, 2024 · The hash is quite sensitive to any change in the input data, however small that may be. Moreover, it's impossible to get the input data back just from its hash. These properties make the hash function quite useful in cryptography. So, let's see how we can generate the hash of our block in Java: * This implementation uses a separate chaining hash table.
