JSSH is a library of Java classes that implement the Secure Shell (SSH) version 1.5
client protocol. It is designed as a reusable component that can be embedded
in larger Java applications to provide SSH client functionality.
The library is intended for use in Java applications, not applets (it needs
to access the local filesystem to check whether the server's host key is in the
known_hosts file, and it also needs to access the /dev/random device to obtain
random numbers for the session key). The library was written in pure Java, in
the sense that it does not require an accompanying JNI native library.
The JSSH library is derived from Cedric Gourio's "java-ssh":

The object model has been redesigned from scratch so that (IMHO) it is
more object-oriented and understandable, and I have added port-forwarding and
data-compression functionality, as well as RSA client authentication (the
original version supported username-password authentication only).
JSSH also uses some GPL-licensed cryptographic code from "The Java Telnet
Applet", which can be found at:
