The description is not quite clear to me. Cause: The data received is not the same as the data sent. Action: Attempt the transaction again. If error persists, check (and correct) the integrity of your physical connection.

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. WebI also have a basic understanding of how cryptographic hash functions work. They're more taxing to compute, produce a more randomized output, and generally have a larger output size than a checksum. And somehow they're designed to be secure. However, non-cryptographic functions are a mystery to me. None are really taken seriously or …
