用python对文本文件内容加密

import base64
import pickle


def _save_(file_path, obj):
    output = open(file_path, 'wb')
    a = base64.b64encode(pickle.dumps(str(obj))).decode()
    pickle.dump(a, output)
    print("data saving as % s successfully" % file_path)


def _read_(file_path):
    pkl_file = open(file_path, 'rb')
    load_res = pickle.loads(base64.b64decode(pickle.load(pkl_file)))
    load_res.replace(base64.b64encode(pickle.dumps(file_path)).decode(), '')
    return load_res

代码如上，利用base64对数据内容进行加密、解密。有什么问题，欢迎大家咨询。
