What is a Checksum, and What Can You Do With It? TechSpot

WebSep 30, 2024 · To produce a checksum, you run a program that puts that file through an algorithm. Typical algorithms used for this include MD5, SHA-1, SHA-256, and SHA-512. The algorithm uses a cryptographic hash function that takes an input and produces a string (a sequence of numbers and letters) of a fixed length. 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. reading bc waste tip
