WebDec 11, 2024 · No. SHA256 is secure even when the file size is not included. Including the file size doesn't help in any way. And for MD4, MD5 and SHA-1, which were formerly believed to be secure but now have known collisions, the methods to find collisions allow the colliding messages to have the same size, so including the file size doesn't help either.
