• 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.

• Java-SSH is an SSH1-only implementation, by Cédric Gourio. Comes under a confusing mix of non-commercial and GPL licences.

  "This applet implements the Ssh Protocol 1.5. The Terminal Emulation is almost VT100 compliant. It provides secure communications over insecure networks. All communications are automatically and transparently encrypted. Encryption is also used to protect integrity."

• 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."

• SSH Toolkits for Java. LGPL/GPL Licence.

  "We are currently offering three LGPL/GPL based projects: J2SSH, a SSH2 library, SSHTerm, a terminal client application, and a Windows SSH Server."
