How to validate .ufa files in Python

Python
def is_ufa(file_path: str) -> bool:
    """Check if file is a valid UFA by magic bytes."""
    signature = bytes([0x55, 0x46, 0x41, 0xC6, 0xD2, 0xC1])
    with open(file_path, "rb") as f:
        return f.read(6) == signature

How to validate .ufa files in Node.js

Node.js
function isUFA(buffer: Buffer): boolean {
  const signature = Buffer.from([0x55, 0x46, 0x41, 0xC6, 0xD2, 0xC1]);
  return buffer.subarray(0, 6).equals(signature);
}

How to validate .ufa files in Go

Go
func IsUFA(data []byte) bool {
    signature := []byte{0x55, 0x46, 0x41, 0xC6, 0xD2, 0xC1}
    if len(data) < 6 {
        return false
    }
    return bytes.Equal(data[:6], signature)
}
