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。
