ConceptsCollision Resistance

Collision Resistance

A property of a secure cryptographic hash function meaning it is computationally infeasible to find two different inputs that produce the same hash output. It is what lets a hash reliably stand in for the data it represents.

Hash Functions

Algorithms that take input of any size and produce a fixed-size, unique-looking output (a hash), designed so the same input always yields the same hash and it is infeasible to reverse or to find two inputs with the same hash.
