Hashing

Key characteristics of hashing
One-way function: A hash cannot be reversed to obtain the original data.
Fixed-size output: Regardless of the input size, the hash is always the same length.
Deterministic: The same input always produces the same hash.
Avalanche effect: Even a small change in the input data results in a drastically different hash.
