sshj - SSHv2 library for Java

To get started, have a look at one of the examples. Hopefully you will find the API pleasant to work with :)

Features of the library include:

• reading known_hosts files for host key verification
• publickey, password and keyboard-interactive authentication
• command, subsystem and shell channels
• local and remote port forwarding
• scp + complete sftp version 0-3 implementation

Implementations of the following algorithms are included:

ciphers

aes{128,192,256}-{cbc,ctr}, blowfish-cbc, 3des-cbc

key exchange

diffie-hellman-group1-sha1, diffie-hellman-group14-sha1

signatures

ssh-rsa, ssh-dss

mac

hmac-md5, hmac-md5-96, hmac-sha1, hmac-sha1-96

compression

zlib and zlib@openssh.com (delayed zlib)

private key files

pkcs8 encoded (what openssh uses)

If you need something that is not implemented, it shouldn't be too hard to add (do contribute it!)

Dependencies

Java 6+. slf4j is required. bouncycastle is highly recommended and required for using some of the crypto algorithms. jzlib is required for using zlib compression.

Help and discussion

There is a google group.
