python3.x实现base64加密和解密

python3.x实现base64加密" title="base64加密">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")
