PHP to Python: Decoding and Encoding Logic with MD5 and Base64

if operation == 'DECODE': if (int(result[:10]) == 0 or int(result[:10]) - time.time() > 0) and result[10:26] == hashlib.md5((result[26:] + keyb).encode()).hexdigest()[:16]: return result[26:] else: return '' else: return keyc + base64.b64encode(result.encode()).decode().replace('=', '')
