python密码管理工具
闲来无事写了个密码管理工具，json格式储存，采用AES-128 CBC模式加密需要密钥和偏移一对密码进行加解密
需要模块：`pycryptodome`
1. 初始化json文件
```python
from Crypto.Cipher import AES
data = [
{
"id": "0",
"host": "52pojie.cn",
"username": "",
"password": "",
"history": [],
"notes": "",
"create-time": "",
"update-time": ""
}
]
password = "password".zfill(16)# 设置初始密码
iv = "iv".zfill(16).encode("utf-8")# 设置初始偏移
test = b""
cipher = AES.new(password.encode('utf-8'), AES.MODE_CBC, iv)
data = str(data).encode()
data = data + "\0".encode() * (16 - len(data) % 16)
for i in range(int(len(data) / 16)):
block = data
b = cipher.encrypt(block)
test += b
cipher1 = AES.new(password.encode('utf-8'), AES.MODE_CBC, iv)
test2 = cipher1.decrypt(test)
with open("password.json", "wb") as f:
f.write(test)
```
运行后生成加密后的`password.json`
2. main
```python
import json
import time
import sys
import re
from Crypto.Cipher import AES
class MyPassword:
filename = "password1.json"
def __init__(self):
self.new = {
