文件加密与解密安全方案实战：基于Python的实践

随着信息技术的飞速发展，数据安全已成为企业和个人关注的焦点。文件加密与解密是保障数据安全的重要手段之一。本文将围绕这一主题，通过Python编程语言，实现一个简单的文件加密与解密安全方案，并对其原理和实现过程进行详细解析。

一、加密算法选择

在实现文件加密与解密之前，首先需要选择一种加密算法。常见的加密算法有AES、DES、RSA等。考虑到Python内置库中的加密算法，本文选择AES算法进行文件加密与解密。

AES（Advanced Encryption Standard）是一种对称加密算法，具有速度快、安全性高等特点。Python内置库`cryptography`提供了AES加密算法的实现。

二、加密与解密流程

文件加密与解密流程主要包括以下步骤：

1. 生成密钥（Key）
2. 使用密钥对文件进行加密
3. 将加密后的文件保存到磁盘
4. 使用相同的密钥对加密文件进行解密
5. 将解密后的文件保存到磁盘

三、Python代码实现

1. 生成密钥
