Collision attack

A collision attack is a type of cryptographic attack that targets hash functions. The goal of this attack is to find two distinct inputs that produce the same hash output, which is known as a "collision." Hash functions are designed to take in data and produce a fixed-size string of characters (the hash) that should be unique for unique inputs. In more detail: 1. **Hash Function**: A hash function processes input data and generates a fixed-length string of characters.
