ssh, scp and sftp for java

branch: master

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 / adapters for the following algorithms are included:

aes{128,192,256}-{cbc,ctr}, blowfish-cbc, 3des-cbc
key exchange
diffie-hellman-group1-sha1, diffie-hellman-group14-sha1
ssh-rsa, ssh-dss
hmac-md5, hmac-md5-96, hmac-sha1, hmac-sha1-96
zlib and (delayed zlib)
private key files
pkcs8 encoded (what openssh uses)

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


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.
