Portable OpenSSH
Complete implementation of the SSH protocol
Portable OpenSSH is a cross-platform implementation of the Secure Shell (SSH) protocol that provides encrypted communication and secure remote access over untrusted networks. It originates from the OpenSSH project maintained by the OpenBSD community and adapts the core OpenBSD implementation so it can run on many operating systems including Linux, macOS, and Windows. The software suite enables administrators and developers to securely log into remote systems, transfer files, and create encrypted tunnels for network traffic. By encrypting all communications between client and server, it protects against threats such as eavesdropping, connection hijacking, and data interception. The portable distribution follows the development of the main OpenSSH codebase while adding compatibility layers for multiple operating systems and authentication systems. -

Russh
Rust SSH client & server library
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. -

ssh-chat
Chat over SSH
ssh-chat is a custom SSH server written in Go that allows you to chat over SSH connection. When you open your terminal and type in a command, instead of getting a shell you get a chat prompt. With ssh-chat you get a simple chat room over a secure shell connection, where you can send and receive private messages, check any user's public key fingerprint for identification purposes, and more. You can change the color theme of the chat, block or kick users, and chat on just about any platform where an SSH client is available, including on mobile. -

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

respite HTTP Injector +
Multi-platform Java HTTP Injector
Bypass internet firewalls by connecting to HTTP proxies with custom headers. Purely coded in Java so it supports all platforms. Source Code: https://github.com/AlizerUncaged/HTTP-Injector -
13
http-proxy-tunnel
Create nested tunnels through HTTP proxies
Http-proxy-tunnel creates TCP tunnels through http proxies that permit the CONNECT method. It differs from other proxy tunnelling programs in that it can tunnel through multiple proxies, and can use SSL tunnels. These abilities mean that in combination with a web server that can proxy (such as Apache) you can serve normal web pages from ports 80 and 443 and connect to the server (using ssh say) via those ports at the same time. All available documentation can be read online at http://http-proxy-tunnel.sourceforge.net/ -

MurmurSSH
Lightweight, privacy-focused SSH and SFTP client for Linux.
MurmurSSH is an open-source SSH and SFTP client for Linux, designed as a simple, reliable, and fully local alternative to cloud-based or complex tools. It focuses on clarity and usability, offering a minimal interface, fast connection handling, and straightforward file operations. All profiles and configurations are stored locally — no accounts, syncing, or background services. MurmurSSH supports password and SSH key authentication, including passphrase-protected keys. Host key verification is handled transparently, allowing users to manage trust decisions per session or permanently. The integrated SFTP browser enables efficient file management, including upload, download, move, and recursive transfers with multi-file support. A terminal can be launched externally when needed, keeping workflows flexible without forcing an embedded terminal. -

Compassh
the OpenSSH VPN, without the VPN
Compassh is an helper for the popular OpenSSH remote connection software, focused on providing near-VPN service without the complexity and the setup required by a real VPN. Using a VPN software may require an ad-hoc firewall setup, the generation of a key (pair) and the installation of the VPN software on a host that is not under your control. Compassh try to solve as much of this problems with a smart use of OpenSSH. -

FullAuto
Fully Automate ANY Process with *Persistent* SSH/SFTP from One Host
FullAuto is a groundbreaking secure programming framework that enables FULL API access to any number of simultaneous persistent SSH and SFTP connections to remote resources and devices. With FullAuto, connections are PERSISTANT enabling state preservation of file system navigations, environment manipulations, and user context shifting. Output and error messages from remote commands are returned accurately from both STDOUT and STDERR channels. With FullAuto persisent SSH/SFTP connections, automated processes can be DYNAMIC, intelligent and responsive - precisely in the same manner that highly trained professionals work with SSH/SFTP tools, to perform countless tasks manually. FullAuto works with the naked protocol, and connects directly with ordinary SSH/SFTP servers that already exist on nearly every UNIX platform, and many Windows and MAC systems. NO OTHER REMOTE SOFTWARE IS NEEDED. FullAuto is written entirely in Perl and has been tested on Linux, UNIX and Windows with Cygwin. -
