How to validate .nri files in Python

Python 
def is_nri(file_path: str) -> bool:
    """Check if file is a valid NRI by magic bytes."""
    signature = bytes([0x0E, 0x4E, 0x65, 0x72, 0x6F, 0x49, 0x53, 0x4F])
    with open(file_path, "rb") as f:
        return f.read(8) == signature

How to validate .nri files in Node.js

Node.js 
function isNRI(buffer: Buffer): boolean {
  const signature = Buffer.from([0x0E, 0x4E, 0x65, 0x72, 0x6F, 0x49, 0x53, 0x4F]);
  return buffer.subarray(0, 8).equals(signature);
}

How to validate .nri files in Go

Go

    if len(data) < 8 {
        return false
    }
    return bytes.Equal(data[:8], signature)
