## Description

This project is a portable implementation of the secure shell toolset designed for deployment across diverse operating systems and platforms. It provides a suite of tools for secure remote login and command execution based on the secure shell protocol.

The implementation includes a sandboxed server that isolates processes to limit the impact of potential vulnerabilities on the host operating system. It also functions as a cryptographic key manager for generating and storing security keys to replace or supplement password-based authentication.

The project covers encrypted file transfer for moving data between hosts, system authentication integration for managing user identities and logs, and secure remote access.
