How to validate .mka files in Python

Python
def is_mka(file_path: str) -> bool:
    """Check if file is a valid MKA by magic bytes."""
    signature = bytes([0x1A, 0x45, 0xDF, 0xA3])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .mka files in Node.js

Node.js
function isMKA(buffer: Buffer): boolean {
  const signature = Buffer.from([0x1A, 0x45, 0xDF, 0xA3]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .mka files in Go

Go
func IsMKA(data []byte) bool {
    signature := []byte{0x1A, 0x45, 0xDF, 0xA3}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}

How do I validate a .mka file?

To validate a .mka file, read the first bytes of the file and compare them against the known magic bytes (1A 45 DF A3) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
