J2SSH is an object-orientated Java library implementation of the SSH version 2 protocol. It provides a rich, powerful, and extensible SSH API that enables developers to gain access to SSH servers and to develop entire SSH client/server frameworks. The API library provides a fully-featured SSH2 implementation specifically designed for cross-platform development.
