RegentLock – 桌面/离线应用程序的软件许可
1 分•作者: fintexa•6 个月前
我为桌面和企业软件构建了一个授权许可系统。发帖是为了宣传并从 HN 获取反馈。<p><pre><code> 我遇到的问题
我销售商业工程软件（核/热工水力学仿真工具）。我的客户经常在隔离环境中工作——政府实验室、国防承包商、以及拥有严格 IT 政策的公用事业公司。现有的授权许可解决方案要么假设始终在线连接，要么需要重量级的 SDK，要么定价针对财富 500 强公司。
RegentLock 的作用
这是一个用于生成、激活和管理软件许可证的授权许可后端 + API。加密技术很简单：使用 Ed25519 进行签名，ChaCha20-Poly1305 进行许可证文件加密。许可证在激活后在本地进行验证——无需回传（尽管您可以根据需要配置签到策略）。
支持：
- 节点锁定和浮动许可证
- 离线/隔离环境激活（生成请求文件 → 在已连接的机器上处理 → 传输许可证）
- 可重新托管的许可证（客户可以撤销许可证并将其移动到新硬件上）
- 通过 MAC 地址、磁盘序列号或便携式“可重新托管” ID 进行硬件绑定
集成
REST API。我提供了 C、Go、Python、Java 和 C# 的集成示例。典型的集成大约需要 50-100 行代码——在启动时验证许可证、检查过期时间、验证签名。
定价
独立开发者套餐，每年 349 美元，适用于单人开发者（500 次激活）。入门套餐为每年 1,499 美元。我不想与 Gumroad 竞争 10 美元的电子书市场——这适用于需要真正保护的软件。
我正在寻找什么
- 关于该方法的反馈
- 我尚未考虑到的边缘情况
- 该功能集是否适合您的用例

I built a licensing system for desktop and enterprise software. Posting to get the word out and get feedback from HN.<p><pre><code> The problem I had
I ship commercial engineering software (nuclear/thermal-hydraulics simulation tools). My customers often work in air-gapped environments - government labs, defense contractors, utilities with strict IT policies. Existing licensing solutions either assumed always-online connectivity, required heavyweight SDKs, or were priced for Fortune 500 companies.
What RegentLock does
It's a licensing backend + API for generating, activating, and managing software licenses. The crypto is straightforward: Ed25519 for signing, ChaCha20-Poly1305 for license file encryption. Licenses are validated locally after activation - no phone-home required (though you can configure check-in policies if you want).
Supports:
- Node-locked and floating licenses
- Offline/air-gapped activation (generate request file → process on connected machine → transfer license back)
- Rehostable licenses (customers can revoke and move to new hardware)
- Hardware binding via MAC, disk serial, or a portable "rehostable" ID
Integration
REST API. I have integration examples for C, Go, Python, Java, and C#. Typical integration is ~50-100 lines - validate license on startup, check expiration, verify signature.
Pricing
Indie tier at $349/year for solo devs (500 activations). Starter is $1,499/year. I'm not trying to compete with Gumroad for $10 e-books - this is for people shipping software that actually needs protection.
What I'm looking for
- Feedback on the approach
- Edge cases I haven't considered
- Whether the feature set makes sense for your use case
