一、前言
现在，互联网上的安全问题越来越严重。我们的文件虽然有杀毒软件保护，但光使用杀毒软件也不是完全安全的。于是，有了很多人选择了文件加解密工具，保护自己的文件。这样黑客即使拿到了文件，也无法破解掉文件的内容。
要想保护文件，使用公用的加密算法是不太安全的，所以我们要想更好地保护文件，需要制作一个加密算法。

二、思路
（1）加密算法的实现
这个加密算法我已经实现出来了，名字叫做Dx2，在其之前有Dx1，但是并不安全，Dx1设计思路如下：
①先生成一个固定的包含所有ASCII字符的字符串，后将其生成为映射字典。
②读取文件内容，使用公用的加密算法（我使用了ascii85）加密，然后根据映射字典生成映射数字的序列，实现加密。一旦黑客得到映射字典，那就可以破解文件内容了。
③创建一个新文件，将加密内容写入。
旧一代的加密算法如下（使用的是模块形式）：
from base64 import a85encode,a85decode
marks = {}
string = '0123456789AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz`~@#$%^&*()_+{}|\/{}[]<>?:;"\'=+-.,!'
for i in range(0,len(string)):
if i <= 9:
marks['0' + str(i)] = string[i]
else:
marks[str(i)] = string[i]
class __Daoxi():
def __init__(self):
self.content = 'Daoxi Encode'
self.interval_mark = '-'
self.ec = 'UTF-8'
self.marks = marks
def encode(self):
try:
text = a85encode(self.content.encode(self.ec)).decode(self.ec)
letters = []
for i in text:
letters.append(list(marks.keys())[list(marks.values()).index(i)])
return ['OKAY',self.interval_mark.join(letters)]
except Exception as e:
return ['ERROR',e]
def decode(self):
try:
text = self.content.split(self.interval_mark)
letters = []
for i in text:
letters.append(marks[i])
result = ''.join(letters)
return ['OKAY',a85decode(result.encode(self.ec)).decode(self.ec)]
except Exception as e:
return ['ERROR',e]
daoxi = __Daoxi()
新一代解决了这个问题，实现了“一次一密”。包含内容：
dx1(文件内容)……+md5(密码)+dx1(str(映射字典))

（二）GUI等的实现
其实很简单，该怎么做就怎么做，请看第三部分代码实现。
三、代码实现
导入需要用到的模块：
# 导入需要用到的模块
from tkinter import Tk
from tkinter.filedialog import askopenfilename
from easygui import buttonbox, msgbox,passwordbox
from tkinter.messagebox import showinfo, showwarning, showerror
from os import name, environ
from hashlib import md5
from random import shuffle
from base64 import (
a85encode,
a85decode,
b64encode,
b64decode,
b32encode,
b32decode,
b16encode,
b16decode,
)
先创建两个功能函数：
#生成随机字符串集合
def shuffle_str(s):
str_list = list(s)
shuffle(str_list)
return "".join(str_list)
#生成md5值储存密码
def create_md5(s):
enc = md5(s.encode()).hexdigest()
return enc
声明变量及隐藏tkinter窗口：
#设置加密字典和映射字典
dx1marks = {}
dx1dict = "0123456789AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz`~@#$%^&*()_+{}|\/{}[]<>?:;\"'=+-.,! "
# 声明变量
title = "文件通文件加解密工具"
ec = "UTF-8"
button = "确定"
userprofile = environ["Userprofile"].replace("\\", "/")
states = 'RUNNING'
# 隐藏窗口
hide = Tk()
hide.withdraw()
分配到Dx1字典：
#分配到字典
for i in range(0, len(dx1dict)):
if i <= 9:
dx1marks["0" + str(i)] = dx1dict[i]
else:
dx1marks[str(i)] = dx1dict[i]
如下为Dx1算法的实现：
#dx1低级加密算法
class Dx1:
#设定属性
def __init__(self):
self.content = "DaoXi 1.0/2.0 Encrypt Decrypt Algorithm Library"
self.interval_mark = "-"
self.ec = "UTF-8"
self.dx1dx1marks = dx1marks
#加密函数
def encrypt(self):
text = a85encode(self.content.encode(self.ec)).decode(self.ec)
letters = []
for i in text:
letters.append(list(dx1marks.keys())[list(dx1marks.values()).index(i)])
return ["OKAY", self.interval_mark.join(letters)]
#解密函数
def decrypt(self):
try:
text = self.content.split(self.interval_mark)
letters = []
for i in text:
letters.append(dx1marks[i])
result = "".join(letters)
return ["OKAY", a85decode(result.encode(self.ec)).decode(self.ec)]
except Exception as e:
return ["ERROR", e]
#dx1算法加密函数
def dx1encrypt(content, interval="-"):
dx1 = Dx1()
dx1.content = content
dx1.interval_mark = interval
text = dx1.encrypt()
if text[0] == "OKAY":
return text[1]
else:
return "Error! " + text[1]
#dx1算法解密函数
def dx1decrypt(content):
dx1 = Dx1()
dx1.content = content
text = dx1.decrypt()
if text[0] == "OKAY":
return text[1]
else:
return "Error! " + str(text[1])
