How to validate .mte files in Python

Python 
def is_mte(file_path: str) -> bool:
    """Check if file is a valid MTE by magic bytes."""
    signature = bytes([0x4D, 0x43, 0x57, 0x20, 0x54, 0x65, 0x63, 0x68, 0x6E, 0x6F, 0x67, 0x6F, 0x6C, 0x69, 0x65, 0x73])
    with open(file_path, "rb") as f:
        return f.read(16) == signature

How to validate .mte files in Node.js

Node.js 
function isMTE(buffer: Buffer): boolean {
  const signature = Buffer.from([0x4D, 0x43, 0x57, 0x20, 0x54, 0x65, 0x63, 0x68, 0x6E, 0x6F, 0x67, 0x6F, 0x6C, 0x69, 0x65, 0x73]);
  return buffer.subarray(0, 16).equals(signature);
}

How to validate .mte files in Go

Go 
func IsMTE(data []byte) bool {
    signature := []byte{0x4D, 0x43, 0x57, 0x20, 0x54, 0x65, 0x63, 0x68, 0x6E, 0x6F, 0x67, 0x6F, 0x6C, 0x69, 0x65, 0x73}
    if len(data) < 16 {
        return false
    }
    return bytes.Equal(data[:16], signature)
}

How do I validate a .mte file?

To validate a .mte file, read the first bytes of the file and compare them against the known magic bytes (4D 43 57 20 54 65 63 68 6E 6F 67 6F 6C 69 65 73) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
