What is it?

The Hopefully Uncomprehensible Shell, or HUSH for short, simply enough, is a Java implementation of the Secure Shell protocol. Its primary goal is to create an easy way to use the SSH protocol in Java programs, but will include console-based and graphical client programs.

HUSH is free software; you can redistribute and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation.

Protocols

Version 1.5: "The SSH (Secure Shell) Remote Login Protocol".

Version 2:

• SSH Protocol Architecture
• SSH Transport Layer Protocol
• SSH Authentication Protocol
• SSH Connection Protocol

Features

• Nearly-complete SSH protocol version 2 programming API.
• A console-based client program that can be used with UN*X-like systems.
• A GUI client program for everyone else, based on the last free version of MindTerm, with significant improvements.
• An interpreter for X's portable compiled format bitmap fonts.

Cryptography

This project does not include any cryptographic primitives such as ciphers or key agreement algorightms. Instead, it relies on the appropriate implementations of these algorithms being installed as a Java Cryptography Extension provider.

Keeping in the spirit of free software the recommended provider (at the moment) is the Legion of the Bouncy Castle's. As it matures, the GNU Cryptography Project will be the provider most recommended.
