获取传世Get Transhi 它是如何工作的How it works

Three pillars

配对 · 发现 · 传递 Pair · Discover · Transfer

三步,把同一张网下的设备连成一只无形的信箱。 Three steps. Every device on your Wi-Fi becomes part of one quiet mailroom.

01

配对

Pair

4 位一次性口令,SPAKE2 密码认证密钥交换。设备相认一次,从此互信。 One 4-character code, SPAKE2 password-authenticated key exchange. Trust each other once, forever.

SPAKE2 · RFC 9382 · Ed25519

02

发现

Discover

mDNS 服务发现,同网设备实时浮现。在线状态每 5 秒一次自我刷新。 mDNS service discovery surfaces every peer on the same LAN. Presence refreshes every 5 seconds.

mDNS · Bonjour · 5 s refresh

03

传递

Transfer

文件按 1 MiB 分块端到端加密,中断可续传。剪贴板 2 秒内跨设备同步。 Files chunked at 1 MiB, end-to-end encrypted, resumable on interruption. Clipboard syncs in under 2 seconds.

X25519 · AES-256-GCM · HKDF-SHA256

"Bridges in air, paths in home."

跨设备的信使,只走家中之径。

Showcase

四端一网,文件与剪贴板同走家中之径

Four platforms. One LAN. Files and clipboard, on the same paths.

FAQ

常见问题 Frequently asked

传世能跨网传输吗? Does it work over the internet?

不行。传世严格只在同一 Wi-Fi(同一广播域)上工作。不同子网、不同网络、蜂窝数据都不可用——这是刻意为之:零中转、零云端、零账号。 No. Transhi is strictly same-Wi-Fi (same broadcast domain). Different subnets, different networks, or cellular don't work. This is intentional: zero middleman, zero cloud, zero accounts.

你们会收集我的数据吗? Do you collect any data?

不会。传世不会联系任何我们运营的服务器。所有流量都留在你的本地网络中。我们也没有任何账号系统可注册。 No. Transhi never contacts any server we operate. All traffic stays on your local network. We do not run an account system to sign up for.

和 AirDrop 有什么不同? How is it different from AirDrop?

AirDrop 只支持苹果设备。传世跨 iOS / macOS / Android / Windows 以及任何浏览器。它还多了一条剪贴板通道,这是 AirDrop 没有的。 AirDrop is Apple-only. Transhi works between iOS, macOS, Android, Windows, and any web browser. It also offers a clipboard channel that AirDrop does not.

为什么是终身买断,而非订阅? Why lifetime and not subscription?

传世是一个局域网工具,没有持续的云端成本要分摊。我们一次性收费,你拥有它——这才是公平的。 Transhi is a LAN tool. There is no ongoing cloud cost to recover. We charge once, and you own it — that's the honest model.

用了哪些加密算法? What encryption is used?

配对用 SPAKE2 (RFC 9382),会话密钥走 X25519 ECDH,身份签名用 Ed25519,有效载荷用 AES-256-GCM(老版本 Android 回退至 ChaCha20-Poly1305),全程 HKDF-SHA256 派生。 SPAKE2 (RFC 9382) for pairing, X25519 ECDH for session keys, Ed25519 for long-term identity signatures, AES-256-GCM for payload (ChaCha20-Poly1305 fallback on older Android). HKDF-SHA256 throughout.

我能自建服务器吗? Can I run my own server?

传世没有可自建的服务器——它本来就没有服务器。每台原生 App 内置了 shelf HTTP / WebSocket 服务,直接处理同网对端与 Web 临时访客。 There is no server to run — Transhi was never designed to have one. Each native app embeds the shelf HTTP / WebSocket service that handles LAN peers and Web guests directly.
