WebJul 5, 2024 · What is a cryptographic hash? Cryptographic hashes provide additional properties over simple checksums (all cryptographic hashes can be used as checksums, but not all checksums are cryptographic hashes). Cryptographic hashes (that aren't broken or weak) provide collision and preimage resistance. WebA cryptographic checksum function (also called a strong hash function or a strong one-way function) h: A → B is a function that has the following properties: For any x ∈ A, h ( x) is easy to compute. For any y ∈ B ,it is computationally infeasible to find x ∈ A such that h ( x) = y.
