WebSo if you have two copies of a file, and they both have the same hash value, you can be certain that they are identical. A hash value guarantees authenticity thanks to four particular characteristics: It is deterministic, meaning that a specific input (or file) wil always deliver the same hash value (number string). WebFeb 5, 2024 · Yes, if you hash the same input with the same function, you will always get the same result. This follows from the fact that it is a hash- function. By definition a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

WebAug 4, 2015 · Assuming a non-broken cryptographic hash, two files have the same hash if and only if they have the same contents. The most common such hashes are the SHA-2 family (SHA-256, SHA-384, SHA-512) and the SHA3 family.
