• MindTerm 1 is an SSH1-only implementation. GPL Licence.

  "MindTerm is an entirely FREE(*) SSH protocol 1 client program written in 100% pure Java (non-certified). It is distributed with source code since we believe that security related software can't otherwise be seriously trusted. MindTerm can be run as a stand-alone program or as an applet in a webpage. It can be run with or without a GUI (stand-alone). It has two notable features setting it apart from some other clients, built in scp file transfer and a special ftp-tunnel which works with "ordinary" ftpd's "behind" the sshd."

  NOTE: Mindterm 2 is not free.

• SSH Plugin is an SSH1-only implementation, by Matthias L. Jugel and Marcus Meißner. GPL Licence.

  "This implementation of SSH provides IDEA and RSA/PKCS#1 encryption and was originally written in 1998 by Cédric Gourio. He used a part of the old Java Telnet Applet to write his Java SSH client and so the code was similar to our old applet."

• Ganymed SSH-2 for Java. BSD style license.

  "Ganymed SSH-2 for Java is a freely available open-source library which implements the SSH-2 protocol in pure Java. It supports SSH sessions (remote command execution and shell access), local and remote port forwarding, local stream forwarding, X11 forwarding, SCP and SFTP. There are no dependencies on any JCE provider, as all crypto functionality is included."
