## 项目历史与用法

SSH3 is an experimental secure-shell implementation and research prototype that maps SSH connection semantics onto HTTP/3, QUIC, TLS 1.3, and HTTP authorization mechanisms. Its appeal in package-manager culture is that it lets developers install and test a speculative next-generation remote-login protocol with familiar `ssh3` and `ssh3-server` commands.

### 项目历史

The project comes from research by Francois Michel and Olivier Bonaventure. The arXiv paper 'Towards SSH3: how HTTP/3 improves secure shells' was submitted on 12 December 2023, and the repository README says the work was proposed as an Internet-Draft later renamed 'Remote Terminals over HTTP/3'.

### 采用历史

SSH3 is intentionally presented as experimental and not yet appropriate for production systems without further review. Its packaging in Homebrew, MacPorts, and Scoop reflects early-adopter interest rather than mature infrastructure adoption.

### 使用方式

The official README documents installation with `go install github.com/francoismichel/ssh3/cmd/...@latest`, a client named `ssh3`, and a server named `ssh3-server`. It reuses familiar SSH concepts such as `~/.ssh/authorized_keys`, `~/.ssh/config`, identity files, agent use, and proxy jumps while adding HTTP/3-specific ideas such as URL paths, X.509 certificates, OpenID Connect, and UDP forwarding.

### 为什么软件包爱好者会关心

Package nerds care because SSH3 is a rare example of a research protocol that is immediately packaged as a CLI for hands-on testing. It is useful for comparing old SSH assumptions with modern transport and identity plumbing, while its experimental status keeps it in the sandbox/lab category.
