How to validate .pgd files in Python

Python 
def is_pgd(file_path: str) -> bool:
    """Check if file is a valid PGD by magic bytes."""
    signature = bytes([0x50, 0x47, 0x50, 0x64, 0x4D, 0x41, 0x49, 0x4E])
    with open(file_path, "rb") as f:
        return f.read(8) == signature

How to validate .pgd files in Node.js

Node.js 
function isPGD(buffer: Buffer): boolean {
  const signature = Buffer.from([0x50, 0x47, 0x50, 0x64, 0x4D, 0x41, 0x49, 0x4E]);
  return buffer.subarray(0, 8).equals(signature);
}

How to validate .pgd files in Go

Go 
func IsPGD(data []byte) bool {
    signature := []byte{0x50, 0x47, 0x50, 0x64, 0x4D, 0x41, 0x49, 0x4E}
    if len(data) < 8 {
        return false
    }
    return bytes.Equal(data[:8], signature)
}
