// ==================== 激活系统设计说明 ====================
|
|||
|
|
// 激活文件后缀: .gal (Geton Again License)
|
|||
|
|
// 激活文件内容: 一行加密字符串
|
|||
|
|
// 加密前格式: "UUID:数字密码"
|
|||
|
|
//
|
|||
|
|
// 加密方式（多层混淆）:
|
|||
|
|
// 1. SHA256哈希校验头（8字节）
|
|||
|
|
// 2. XOR密钥加密
|
|||
|
|
// 3. 非线性字节置换 (c * 7 + 13) % 256
|
|||
|
|
// 4. 位置相关混淆
|
|||
|
|
// 5. Base64编码
|
|||
|
|
//
|
|||
|
|
// 验证流程:
|
|||
|
|
// 1. 读取激活文件，多层解密
|
|||
|
|
// 2. 校验SHA256哈希确保完整性
|
|||
|
|
// 3. 解析出UUID和密码
|
|||
|
|
// 4. 对比UUID与本机真实UUID
|
|||
|
|
// 5. 验证密码是否等于程序内置密码
|
