2025-08-09通过授权码的方式给exe程序充值
主要点：
一次性授权机制： 新增 .used_licenses 文件记录所有已使用的授权码 每次激活前检查授权码是否在已使用列表中 激活成功后立即将授权码标记为已使用 时效性验证： 授权码包含过期时间戳（默认 24 小时有效） 超过有效期的授权码无法使用 防止用户长期保存授权码多次使用 授权码格式升级： 新格式：次数|过期时间戳|哈希值（例如：50|1620000000|xxxxxxxxxxx） 时间戳精确到分钟，确保唯一性
使用流程：
开发者生成授权码： 运行 license_generator.py 输入次数（如 50）和有效期（如 24 小时） 生成授权码并发送给用户 用户使用授权码： 在程序中输入授权码并激活 系统验证通过后增加次数并记录此授权码 再次使用同一授权码会提示 "已被使用"
首先创建一个授权码生成工具（开发者使用）：

- 批量购买可享受优惠，详情请咨询开发者
使用说明：
1. 在输入框中填写Behance项目URL，多个URL用逗号分隔
2. 点击"开始下载"按钮进行下载
3. 每次下载会消耗1次使用次数
4. 次数用尽后，请联系开发者充值
5. 充值后将获得授权码，输入授权码即可继续使用
