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-8import base64var = 1while 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-8import base64import loggingimport 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")
