Low-level Tokio SSH2 client and server implementation.

Examples:simple client,interactive PTY client,server,SFTP client,SFTP server.

This is a fork ofThrussh by Pierre-Étienne Meunier.

• Exceptions are checked manually

• When the Rust allocator fails to allocate memory during a CryptoVec being resized.
• Whenmlock/munlock fails to protect sensitive data in memory.

• cryptovec usesunsafe for faster copying, initialization and binding to native API.

• russh-sftp - server-side and client-side SFTP subsystem support forrussh - seerussh/examples/sftp_server.rs orrussh/examples/sftp_client.rs.
• async-ssh2-tokio - simple high-level API for running commands over SSH.

• HexPatch - A binary patcher and editor written in Rust with terminal user interface (TUI).
  • Usesrussh::client andrussh_sftp::client to allow remote editing of files.
• kartoffels - A game where you're given a potato and your job is to implement a firmware for it
  • Usesrussh:server to deliver the game, usingratatui as the rendering engine.
• kty - The terminal for Kubernetes.
  • Usesrussh::server to deliver theratatui based TUI andrussh_sftp::server to providescp based file management.
• lapdev - Self-Hosted Remote Dev Environment
  • Usesrussh::server to construct a proxy into your development environment.
• medusa - A fast and secure multi protocol honeypot.
  • Usesrussh::server to be the basis of the honyepot.
• rebels-in-the-sky - P2P terminal game about spacepirates playing basketball across the galaxy
  • Usesrussh::server to deliver the game, usingratatui as the rendering engine.
• warpgate - Smart SSH, HTTPS and MySQL bastion that requires no additional client-side software
  • Usesrussh::server in addition torussh::client as part of the smart SSH functionality.
• Devolutions Gateway - Establish a secure entry point for internal or external segmented networks that require authorized just-in-time (JIT) access.
  • Usesrussh::client for the web-based SSH client of the standalone web application.
• Sandhole - Expose HTTP/SSH/TCP services through SSH port forwarding. A reverse proxy that just works with an OpenSSH client.
  • Usesrussh::server for reverse forwarding connections, local forwarding tunnels, and theratatui based admin interface.
