Args: fileobj (file-like object): The File object to compute sha256 for, typically obtained with `open(path, "rb")` chunk_size (`int`, *optional*): The number of bytes to read from `fileobj` at once, defaults to 1MB.

This is equivalent to running `git hash-object`. See https://git-scm.com/docs/git-hash-object for more details. Note: this method is valid for regular files. For LFS files, the proper git hash is supposed to be computed on the pointer file content, not the actual file content. However, for simplicity, we directly compare the sha256 of the LFS file content when we want to compare LFS files. Args: data (`bytes`): The data to compute the git-hash for. Returns: `str`: the git-hash of `data` as an hexadecimal string. Example: ```python >>> from huggingface_hub.utils.sha import git_hash >>> git_hash(b"Hello, World!")
