Ganymed SSH-2 for Java

Ganymed SSH-2 for Java is an open source library which implements the SSH-2 protocol in pure Java (tested on J2SE 1.4.2 and 5.0). It allows one to connect to SSH servers from within Java programs. 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.

Originally, Ganymed SSH-2 for Java was developed for the Ganymed replication project at ETH Zurich (Switzerland).

Ganymed SSH-2 for Java is the de-facto standard for open source based SSH communication in Java software. The library is used in many industrial products but also in open source software, e.g., in the widely used SVN plugin for Eclipse and in Cyberduck (a popular SFTP client for the Mac).
