XOR加密

coding=utf-8

md5算法

import hashlib

h_md5 = hashlib.md5()

x = input("输入需要加密的数据:")

print( "Text：",x)

data = x.encode('utf-8', errors='ignore')

h_md5.update(data)

md5_str = h_md5.hexdigest()

print("MD5：",md5_str)

形成key

随机生成十六进制0～F

from random import *

n = "".join([choice("0123456789ABCDEF") for i in range(32)])

print ( "key：", n)

xor运算

txt1 = []

k = ''

u = ''

for a in range(32):

i = '0x' + md5_str[a]

j = '0x' + n[a]

x=bin(eval(i)).replace('0b','')

y=bin(eval(j)).replace('0b','')

for c in range(min(len(x),len(y))):

if (x[-c] == y[-c]) :

e = '0'

elif(x[-c] != y[-c]):

e = '1'

k = e + k

k ='0b' + k

d = k

k = ''

s = hex(eval(d)).replace('0x','')

u = u + s

print("CipherText：",u)

编写过程中参考了同学的。md5算法和随机生成的Key都很好理解，但在最后xor运算上遇到了困难，需要加强学习。
