用python编写具体代码块加密支持中英文混合,要有文件操作,并用图形化界面

在Python中,我们可以使用`pycryptodome`库来实现文件内容的加密,包括中英文混合文本。同时,我们可以利用`tkinter`库创建简单的图形用户界面。以下是一个基本的示例,展示如何做到这一点:
首先,安装所需库:
```bash
pip install pycryptodome tkinter
```
然后,创建一个名为`encrypt_file.py`的文件,编写以下代码:
```python
from tkinter import Tk, filedialog, messagebox
from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
import os
# 初始化AES加密
key = b'sixteen_byte_key' # 可以替换为更安全的密钥
cipher = AES.new(key, AES.MODE_CBC)
def encrypt_text(text):
ciphered_text = cipher.encrypt(pad(text.encode('utf-8'), AES.block_size))
return ciphered_text
def decrypt_text(ciphered_text):
deciphered_text = unpad(cipher.decrypt(ciphered_text), AES.block_size).decode()
return deciphered_text
def select_file():
input_path = filedialog.askopenfilename(filetypes=(("Text files", "*.txt"), ("All Files", "*.*")))
if not input_path:
return
with open(input_path, 'r', encoding='utf-8') as file:
original_text = file.read()
encrypted_text = encrypt_text(original_text)
output_path = filedialog.asksaveasfilename(initialdir=os.getcwd(), defaultextension=".enc")
with open(output_path, 'wb') as out_file:
out_file.write(encrypted_text)
print(f"Original text encrypted and saved to {output_path}")
messagebox.showinfo("Success", "File encrypted successfully.")
def main():
root = Tk()
root.title("File Encryption UI")
btn_encrypt = Button(root, text="Encrypt File", command=select_file)
btn_encrypt.pack(pady=10)
root.mainloop()
if __name__ == "__main__":
main()
```
这个程序创建了一个窗口,当点击“Encrypt File”按钮时,会弹出一个文件选择框让用户选择源文件,读取内容,加密后保存到新的文件,并显示成功消息。
