What is Cryptographic Hashing?
A hash function is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash). It is designed to be a one-way function, meaning it is infeasible to invert or reverse the hash back to the original text.
Key properties of a good hash function:
- Deterministic: The same input always produces the same hash.
- Fast: It is quick to compute the hash for any given data.
- Collision Resistant: It is extremely difficult to find two different inputs that produce the same hash.
- Avalanche Effect: A small change in input (like changing one character) produces a significantly different hash.
