Russh

Low-level Tokio SSH2 client and server implementation.

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

This is a fork of Thrussh by Pierre-Étienne Meunier.

Safety

deny(clippy::unwrap_used)
deny(clippy::expect_used)
deny(clippy::indexing_slicing)
deny(clippy::panic)
Exceptions are checked manually

Panics

When the Rust allocator fails to allocate memory during a CryptoVec being resized.

Unsafe code

cryptovec uses unsafe for faster copying, initialization and binding to native API.

Ecosystem

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