如何用Python加密任何类型的文件？

from cryptography.fernet import Fernet

# 生成对称密钥
key = Fernet.generate_key()

# 创建Fernet对象
cipher_suite = Fernet(key)

# 加密文件
def encrypt_file(file_path):
    with open(file_path, 'rb') as file:
        file_data = file.read()
        encrypted_data = cipher_suite.encrypt(file_data)
    with open(file_path + '.encrypted', 'wb') as encrypted_file:
        encrypted_file.write(encrypted_data)

# 解密文件
def decrypt_file(file_path):
    with open(file_path, 'rb') as encrypted_file:
        encrypted_data = encrypted_file.read()
        decrypted_data = cipher_suite.decrypt(encrypted_data)
    with open(file_path[:-10], 'wb') as decrypted_file:
        decrypted_file.write(decrypted_data)

# 加密文件示例
encrypt_file('example.txt')

# 解密文件示例
decrypt_file('example.txt.encrypted')
