使用Python创建包含各种凭据的加密文件

import json
import cryptography
from cryptography.fernet import Fernet

credentials = {
    "username": "example_username",
    "password": "example_password",
    "api_key": "example_api_key"
}

credentials_json = json.dumps(credentials)

key = Fernet.generate_key()

cipher_suite = Fernet(key)

encrypted_credentials = cipher_suite.encrypt(credentials_json.encode())

with open("encrypted_credentials.txt", "wb") as file:
    file.write(encrypted_credentials)

with open("encrypted_credentials.txt", "rb") as file:
    encrypted_credentials = file.read()

cipher_suite = Fernet(key)

decrypted_credentials = cipher_suite.decrypt(encrypted_credentials)

credentials = json.loads(decrypted_credentials)
