Hash Format Converter

A utility for computing file hashes and providing them in different output formats.

Requirements

Build a utility function that computes the hash of a file and provides the hash in multiple output formats. The function should:

1. Accept a file path as input
2. Compute a 64-bit hash of the file contents
3. Return the hash in three different formats:
   • Raw binary bytes (big-endian representation)
   • Hexadecimal string (lowercase)
   • Integer representation

API

def compute_hash_formats(file_path: str) -> dict:
    """
    Computes a 64-bit hash of the file and returns it in multiple formats.

    Args:
        file_path: Path to the file to hash

    Returns:
        Dictionary with keys 'bytes', 'hex', and 'int' containing the hash in each format

    Raises:
        FileNotFoundError: If the file does not exist
    """

Test Cases

• Given a file containing "hello world", the function returns a dictionary with all three format types (bytes, hex, int) and the hex value matches the bytes value when converted @test
• Given the same file hashed twice, all three formats (bytes, hex, int) are consistent with each other - hex is the hexadecimal representation of bytes, and int equals bytes interpreted as big-endian integer @test
• Given an empty file, the function returns valid hashes in all three formats @test
• Given a file that does not exist, the function raises FileNotFoundError @test
