SSHClient

A small SSH client written in C#.

Usage

You can grab a copy of SSHClient from the releases page. Alternatively, feel free to compile the solution yourself. Fody/Costura has been used to embed the SSH.NET reference.

[+] File downloaded to: C:\Users\skawa\Documents\file.txt

Roadmap

The below techniques are on the roadmap for future releases

Upload files
Perhaps add an option to customize the the downloads directory, this is currently C:\\Users\\Username\\Documents\\
Authentication based on users session
