#coding=utf-8

#md5算法
import hashlib
h_md5 = hashlib.md5()
x = input("请输入要加密的文字:")
print( "Text：",x)
data = x.encode('utf-8', errors='ignore')   #加密，同时忽略可能带来的错误
h_md5.update(data)
md5_str = h_md5.hexdigest()
print("MD5：",md5_str)


#形成key
#随机生成一个32位的十六进制，0～F，作为一次性key
from random import *
n = "".join([choice("0123456789ABCDEF") for i in range(32)]) 
print ( "Key：", n)


#xor运算

    x=bin(eval(i)).replace('0b','')        #十六进制转二进制
