Bagaimana untuk membuka fail yang disulitkan dalam python

<code>pip install cryptography</code>

<code class="python">import cryptography
from cryptography.fernet import Fernet</code>

<code class="python">encryption_key = b'' # 这里填写您的加密密钥字节字符串</code>

<code class="python">fernet = Fernet(encryption_key)</code>

<code class="python">with open('encrypted_file.txt', 'rb') as f:
    encrypted_data = f.read()</code>

<code class="python">decrypted_data = fernet.decrypt(encrypted_data)</code>

<code class="python">with open('decrypted_file.txt', 'wb') as f:
    f.write(decrypted_data)</code>

<code class="python">import cryptography
from cryptography.fernet import Fernet

encryption_key = b'YOUR_ENCRYPTION_KEY_BYTE_STRING'
fernet = Fernet(encryption_key)

with open('encrypted_file.txt', 'rb') as f:
    encrypted_data = f.read()

decrypted_data = fernet.decrypt(encrypted_data)

with open('decrypted_file.txt', 'wb') as f:
    f.write(decrypted_data)</code>
