JSch is a pure Java implementation of SSH2. JSch allows you to connect to an SSH server and use port forwarding, X11 forwarding, file transfer, etc., and you can integrate its functionality into your own Java programs.

Why JSch?

Originally, our motivation to develop this stuff is to allow users of our pure java X servers, WiredX, to enjoy secure X sessions. So, our efforts had mostly targeted to implement the SSH2 protocol for X11 forwarding. Of course, however, we are now also interested in adding other functionality like port forward, file transfer, terminal emulation, etc.

Features:

JSch is in pure Java, but it depends on Java Cryptography Extension (JCE). JSch is know to work with:
- J2SE 1.4.0 or later (no additional libraries required).
- J2SE 1.3 and Sun's JCE reference implementation that can be obtained at http://java.sun.com/products/jce/.
- J2SE 1.2.2 and later and Bouncycastle's JCE implementation that can be obtained at https://www.bouncycastle.org/.
