Open Source Libraries

Russh provides a Rust library for implementing SSH clients and servers with a modern, async-friendly design. It exposes building blocks for authentication, channel management, port forwarding, and key handling, allowing you to embed SSH functionality directly into Rust applications. The API is designed to be explicit and composable, making it possible to implement custom behaviors like reverse tunnels, interactive shells, and service multiplexing. Because performance and safety are central, the code leverages Rust’s type system to reduce classes of runtime errors common in network protocol implementations. The project also includes examples and discussion threads that show how other tools integrate it for web-based clients or gateway services. For teams building terminals, proxies, or embedded management planes, it offers a robust foundation without shelling out to external binaries.

Libpwmd provides an API for connecting to pwmd. It allows for your application to easily store and retrieve data from a pwmd server. It does all the work of setting up the socket and socket IO. Fetching element content can be done in as little as 4 function calls: pwmd_new(), pwmd_connect(), pwmd_open() and pwmd_command().

DotNetSSH is a pure .NET implementation of the SSH2 client protocol suite. DotNetSSH development is alive and active. DotNetSSH is a fork of Tamir's excellent SharpSSH, itself is a port of JCraft's java Jsch.

Java Library implementing the Client side of RFC4741 and its Transport(s)

Please use https://code.google.com/p/ganymed-ssh-2/ , as this current project is not getting the attention it should and therefore should be considered as 'parked'. Orion SSH for Java is a library which implements the SSH-2 protocol in pure Java. This is the new name, and home, for Trilead SSH (formerly Ganymed SSH2).

Paul Thomas's Performance Tuned SSH, aka PTssh. A cross-platform, high-performance, multi-threaded, thread-safe library implementing the SSH2 protocol and SFTP version 3.
