SSHJ Example of Public Key Auth from File

Question

Can someone give me an example of using SSHJ for Public Key Authentication? I realise this question is essentially identical to ssh example of private/public key authenticat

Answer 1

I just had this issue as well. I ended up changing

client.authPublickey(user, "id_rsa.pub")

to

client.authPublickey(user, client.loadKeys("id_rsa"))

Answer 2

We built the overthere framework on top of SSHJ. Which can connect also connect using key files. The following piece of code should work, but make sure you add the bouncycastle library to your classpath.

SSHClient client = new SSHClient();
String username = "johndoe";
File privateKey = new File("~/.ssh/id_rsa");
KeyProvider keys = client.loadKeys(privateKey.getPath());
client.authPublickey(username, keys);

Hope that helps.
