开发者 Min 在 Hacker News 上展示了名为 Flashpaper 的开源项目，这是一款用于安全共享秘密信息的工具[1]。该应用支持两种自毁方式：阅读后立即销毁或 24 小时后自动过期[1]。
Flashpaper 采用浏览器端加密架构，将密钥存储在链接的井号符后方，确保服务器无法访问用户内容，实现零知识设计[1]。为了降低基础设施成本，该工具采用仅在内存中存储数据的方案，无需使用传统数据库[1]。项目已在 GitHub 发布，采用 MIT 许可证，企业自托管版本采取荣誉制收费模式[1]。
Flashpaper 提供 REST API 和 MCP 服务器支持，允许 AI Agent 集成该工具，并支持一次性领取机制[1]。
Developer Min has unveiled Flashpaper, an open-source tool for secure secret sharing that automatically destroys messages after they are read or expire within 24 hours.[1] The application employs client-side encryption, with cryptographic keys stored in the URL fragment (after the # symbol) and never transmitted to the server, implementing a zero-knowledge architecture that prevents the backend from accessing message content.[1]
To minimize infrastructure costs, Flashpaper operates exclusively from server memory without relying on a database.[1] The platform offers REST API endpoints and supports integration with AI agents through a Model Context Protocol (MCP) server, featuring a one-time retrieval mechanism for enhanced security.[1] The project is available on GitHub under the MIT license, with self-hosted enterprise deployments operating on an honor-based payment system.[1] According to Min, based in Bangkok, this marks the first time the project has been shared with the Hacker News community.[1]
