C# sha256 hash string

WebJan 30, 2024 · To hash a sequence of strings unambiguously, so that any two different sequences yield a different hash, you could prepend every string with its length, e.g. by using decimal representation followed by a separating character (e.g. hyphen). For the strings "abc" and "de" and "" (empty string) and "f" this would look so: hash("3-abc2 … WebThe output of SHA is essentially a number value, without checksums or other additional elements. To answer your question, the only check you can perform is to verify that the potential SHA-256 hash is 256-bits long. In fact, since you can feed arbitrary inputs into the algorithm, any 256-bit value will be a correct SHA-256 hash for some input (s).
