How to validate .gdraw files in Python

Python
def is_gdraw(file_path: str) -> bool:
    """Check if file is a valid GDRAW by magic bytes."""
    signature = bytes([0x7B, 0x22, 0x75, 0x72, 0x6C, 0x22, 0x3A, 0x20, 0x22, 0x68, 0x74, 0x74, 0x70, 0x73, 0x3A, 0x2F])
    with open(file_path, "rb") as f:
        return f.read(16) == signature

How to validate .gdraw files in Node.js

Node.js
function isGDRAW(buffer: Buffer): boolean {
  const signature = Buffer.from([0x7B, 0x22, 0x75, 0x72, 0x6C, 0x22, 0x3A, 0x20, 0x22, 0x68, 0x74, 0x74, 0x70, 0x73, 0x3A, 0x2F]);
  return buffer.subarray(0, 16).equals(signature);
}

How to validate .gdraw files in Go

Go
