How to validate .tbz2 files in Python

Python
def is_tbz2(file_path: str) -> bool:
    """Check if file is a valid TBZ2 by magic bytes."""
    signature = bytes([0x42, 0x5A, 0x68])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .tbz2 files in Node.js

Node.js

  const signature = Buffer.from([0x42, 0x5A, 0x68]);
  return buffer.subarray(0, 3).equals(signature);
}

How to validate .tbz2 files in Go

    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
