There are strictly more strings of 0 through 64 bytes than strings of exactly 64 bytes. Therefore there exist two distinct strings of at most 64 bytes that have the same SHA-512 hash. This is a non-constructive proof. We have absolutely no clue how to actually find two such strings.

WebJul 19, 2024 · CityHash128() and similar return a 128-bit hash and are tuned for strings of at least a few hundred bytes.
