JSch is a pure Java implementation of SSH2.
JSch project allows the user to connect to an sshd server and use port forwarding, X11 forwarding, file transfer, etc., and you can integrate its functionality into your own Java programs. JSch is licensed under BSD style license.
Our intension in developing this stuff is to enable users of our pure java X servers, WiredX and WeirdX, to enjoy secure X sessions. Our efforts have mostly targeted the SSH2 protocol in relation to X window system and X11 forwarding. Of course, we are also interested in adding other functionality - port forward, file transfer, terminal emulation, etc.
Needless to say, SSH provides support for secure remote login, secure file transfer, and secure TCP/IP and X11 forwarding. It can automatically encrypt, authenticate, and compress transmitted data.
The SSH protocol is available in two incompatible varieties: SSH1 and SSH2. SSH2 was invented to avoid the patent issues regarding RSA (RSA patent has expired), and to fix some data integrity problem that SSH1 has, and for a number of other technical reasons.
SSH2 protocol has been standardized on IETF Secure Shell working group and drafts related to SSH2 protocol are available on the web. In developing JSch, we are now referring to following documents:
SSH Protocol Architecture
SSH Transport Layer Protocol
Diffie-Hellman Group Exchange for the SSH Transport Layer Protocol
SSH Connection Protocol
SSH Authentication Protocol
Main features:
- JSch is in pure Java, but it depends on JavaTM Cryptography Extension (JCE). JSch is know to work with:
- J2SE 1.4.0 or later (no additional libraries required).
- J2SE 1.3 and Suns JCE reference implementation that can be obtained at http://java.sun.com/products/jce/.
- J2SE 1.2.2 and later and Bouncycastles JCE implementation that can be obtained at http://www.bouncycastle.org/.
- SSH2 protocol support.
- Key exchange: diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1
- Cipher: blowfish-cbc, 3des-cbc, aes128-cbc,aes192-cbc,aes256-cbcnew!
- MAC: hmac-md5, hmac-sha1, hmac-md5-96, hmac-sha1-96
- Host key type: ssh-dss,ssh-rsa
- Userauth: password
- Userauth: publickey(DSA,RSA)
- Userauth: keyboard-interactive
- X11 forwarding
- xauth spoofing
- connection through HTTP proxy.
- connection through SOCKS5 proxy.
- port forwarding.
- stream forwarding.
- signal sending. The unofficial patch for sshd of openssh will be found in this thread.
- remote exec.
- generating DSA and RSA key pairs.
- changing the passphrase for a private key.
- partial authentication
- SSH File Transfer Protocol(version 0, 1, 2, 3)
- packet compression. JZlib has been used.
- JSch is licensed under BSD style license.
Enhancements:
- bugfix: freeze in diffie-hellman-group-exchange-sha1. FIXED. By the default, diffie-hellman-group1-sha1 will be used and if you have not chosen diffie-hellman-group-exchange-sha1 explicitly, you dont have to worry about it.
- bugfix: there should be timeout mechanism in opening a socket for remote port forwarding. FIXED. At the failure or timeout, SSH_MSG_CHANNEL_OPEN_FAILURE will be sent to sshd.
- bugfix: there should be timeout mechanism in opening a socket for X11 forwarding. FIXED. At the failure or timeout, SSH_MSG_CHANNEL_OPEN_FAILURE will be sent to sshd.

OpenSCDP (Open Smart Card Development Platform) is a collection of tools for the development, test and deployment of smart card applications. It uses the capabilities of Global Platform Scripting, Profile and Messaging technology to provide unparalleled flexibility and development speed.

At its core, OpenSCDP is using JavaScript as the integration glue, linking the functional elements of the platform together. The system integrates a revitalized version of the Open Card Framework and provides cryptographic support through JCE with the Bouncy Castle Crypto API.

Tools, libraries and documentation for the Open Smart Card Development Platform are provided as Open Source under the GNU Public License (GPL). The software can be downloaded and used free of charge.

OpenSCDP is the toolset used by CardContact when providing consulting services to customers. It has been successfully used in major card projects and is utilized by a number of third party companies in their respective products.

Ganymed SSH2 for Java is a library which implements the SSH-2 protocol in pure Java (tested on J2SE 1.4.2 and 5.0).
Ganymed SSH2 for Java 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 and SCP.
There are no dependencies on any JCE provider, as all crypto functionality is included.
Ganymed SSH2 for Java is used in the Ganymed replication project and a couple of other projects here at the IKS group.
Main features:
- 100% Java implementation of the SSH-2 protocol (tested on J2SE 1.4.2 and 5.0)
- No dependency on any JCE provider, all crypto functionality is included in the Ganymed SSH2 for Java library.
- Supports SSH sessions (remote command execution and shell access), X11 forwarding, local and remote port forwarding, local stream forwarding and SCP.
- Thread safe, multiple threads can concurrently execute commands, open shells etc. on the same SSH connection.
- Available ciphers: aes256-ctr, aes192-ctr, aes128-ctr, blowfish-ctr, aes256-cbc, aes192-cbc, aes128-cbc, blowfish-cbc, 3des-ctr and 3des-cbc.
- Supports DSA and RSA server keys (ssh-dss and ssh-rsa). Extensive support for known_hosts file handling.
- Key exchange methods: diffie-hellman-group-exchange-sha1 (parameters configurable), diffie-hellman-group14-sha1 and diffie-hellman-group1-sha1.
- Supported MAC algorithms: hmac-sha1-96, hmac-sha1, hmac-md5-96 and hmac-md5.
- User authentication: password, keyboard-interactive and public-key with DSA and RSA keys (client-side private keys (PEM format) may also be 3DES, DES or AES encrypted).
Enhancements:
- This release has support for SFTP v3, HTTP proxies, connection monitoring, improved port forwarding, better compatibility for the Diffie-Hellman group exchange, and enhancements in the SCP code.
