python - 通过 Tkinter GUI 使用加密技术

Question

所以我一直在做一些关于创建预约系统的类(class)，目前我正在研究员工登录。我希望能够对员工的密码进行加密以便存储和比较。

我的问题是我必须从他们的输入框中获取密码，但结果我不知道如何将数据转换为字节以便对其进行加密。这是我目前所拥有的:

import tkinter as tk
from cryptography.fernet import Fernet

key = Fernet.generate_key()
cipher_suite = Fernet(key)

MEDIUM_FONT = ("Berlin Sans FB", 12)
LARGE_FONT = ("Berlin Sans FB", 16)

#validate function
def validateStylist(window):
    password = bstr(passwordEntry.get())
    cipher_text = cipher_suite.encrypt(password)
    plain_text = cipher_suite.decrypt(cipher_text)
    print(plain_text)

window = tk.Tk()

titleLabel = tk.Label(window, text="Register Stylist", font=LARGE_FONT, bg="#FFC0CB")
titleLabel.grid(columnspan = 4)

#Password
passwordLabel = tk.Label(window, text="Password:", font=MEDIUM_FONT, bg="#FFC0CB")
passwordLabel.grid(row=1,column=3)
passwordVar = tk.StringVar(window)
passwordEntry = tk.Entry(window, textvariable=passwordVar)
passwordEntry.grid(row=2,column=3)

finishButton = tk.Button(window, text="Finish",
                          command=validateStylist(window))
finishButton.grid(row=4, column=3, sticky="ew")

window.mainloop()

Answer 1

您可以在将字符串传递给加密之前将其编码为 utf-8:

password = passwordEntry.get().encode("utf-8")
cipher_text = cipher_suite.encrypt(password)
