Validation Code

How to validate .pcs files in Python

Python 
def is_pcs(file_path: str) -> bool:
    """Check if file is a valid PCS by magic bytes."""
    signature = bytes([0x32, 0x03, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00, 0xFF, 0x00])
    with open(file_path, "rb") as f:
        return f.read(16) == signature

How to validate .pcs files in Node.js

Node.js 
function isPCS(buffer: Buffer): boolean {
  const signature = Buffer.from([0x32, 0x03, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00, 0xFF, 0x00]);
  return buffer.subarray(0, 16).equals(signature);
}

How to validate .pcs files in Go

Go 
func IsPCS(data []byte) bool {
    signature := []byte{0x32, 0x03, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00, 0xFF, 0x00}
    if len(data) < 16 {
        return false
    }
    return bytes.Equal(data[:16], signature)
}
