Script which converts SID (domain/user) to HEX format. Eg "S-1-5-21-3167813660-1240564177-918740779-0" becomes "0105000000000005150000001C00D1BCD181F1492BDFC23606040000"

    # Split values

    # Declare output

    # First element - revision

    # Second element - number of dashes
    dashes = int(data.pop(0))
    output += str(dashes).zfill(2)
    output += str(dashes).zfill(12)

    # Rest of data is in hex
    data = [struct.pack('<Q', int(x)).encode("hex") for x in data]
    data = [x[:8] for x in data]
    output +=  "".join(data)

    return output.upper()
