如何在python中加密JSON

我有一个JSON文件。我正在运行一个python程序，从JSON文件中提取数据。有没有办法用密钥加密JSON文件，这样如果有人随机打开该文件，它将是一堆字符，但是当密钥被输入程序时，它会解密并能够读取它？提前感谢。

是的，您可以加密.json文件。确保通过键入

pip install cryptography

或

如果你在windows上

然后，你可以制作一个类似于我的程序：

#this imports the cryptography package
from cryptography.fernet import Fernet

#this generates a key and opens a file 'key.key' and writes the key there
key = Fernet.generate_key()
file = open('key.key','wb')
file.write(key)
file.close()

#this just opens your 'key.key' and assings the key stored there as 'key'
file = open('key.key','rb')
key = file.read()
file.close()

#this opens your json and reads its data into a new variable called 'data'
with open('filename.json','rb') as f:
    data = f.read()

#this encrypts the data read from your json and stores it in 'encrypted'
fernet = Fernet(key)
encrypted=fernet.encrypt(data)

#this writes your new, encrypted data into a new JSON file
with open('filename.json','wb') as f:
    f.write(encrypted)

请注意，此块：

file = open('key.key','wb')
file.write(key)
file.close()

#this just opens your 'key.key' and assigns the key stored there as 'key'
file = open('key.key','rb')
key = file.read()
file.close()

没有必要。这只是一种将生成的密钥存储在安全位置并读回的方法。如果需要，可以删除该块
