这篇文章主要为大家详细介绍了python3.x实现base64加密和解密，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

用python3.x实现base64加密和解密，供大家参考，具体内容如下

加密

base64_encrypt.py

				?

									#!/usr/bin/python3

									#encoding:utf-8

									import base64

									var = 1

									while var==1:

									  str_encrypt=input("输入要加密的字符串:\n"); 

									  base64_encrypt = base64.b64encode(str_encrypt.encode('utf-8'))

									  print("BASE64加密串:\n"+str(base64_encrypt,'utf-8'))

									  print("按ctrl+c退出程序")

打开windows命令窗口>把加密代码文件拖入黑窗口>回车>输入要加密的字符串>回车完成加密

解密

base64_decrypt.py

				?

									#!/usr/bin/python3

									#encoding:utf-8

									import base64

									import logging

									import sys

									'''

									方式一：简单的logger配置

									log_file = "E:\pythonwork/basic_logger.log"

									logging.basicConfig(filename = log_file, level = logging.INFO)

									'''

									#方式二

									#用base64_decrypt创建日志记录器

									logger = logging.getLogger('base64_decrypt')

									logger.setLevel(logging.DEBUG)

									#创建甚至记录调试消息的文件处理程序

									fh = logging.FileHandler("E:\pythonwork/basic_logger.log")

									fh.setLevel(logging.DEBUG)

									#创建具有较高日志级别的控制台处理程序

									ch = logging.StreamHandler()

									ch.setLevel(logging.ERROR)

									#创建格式化程序并将其添加到处理程序中

									formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

									fh.setFormatter(formatter)

									ch.setFormatter(formatter)

									#将处理程序添加到记录器

									logger.addHandler(fh)

									logger.addHandler(ch)

									while True :

									  global base64_decrypt

									  try:

									    str_decrypt=input("输入BASE64加密串:\n")

									    base64_decrypt = base64.b64decode(str_decrypt.encode('utf-8'))

									    print("BASE64解密串（UTF-8）:\n",str(base64_decrypt,'utf-8'))

									    logger.info("BASE64解密串:\n"+str(base64_decrypt,'utf-8'))

									  except Exception as e:

									    print ("BASE64解密串（UTF-8）异常:", e)

									    print("BASE64解密串（默认字符集）:\n",str(base64_decrypt))

									    base64_decrypt=""

									    logger.info("e:"+ str(e))

									  finally: 

									    print("按ctrl+c退出程序")
