python3.x实现base64加密和解密

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")
