NGit (JGit port) authentication with SSH on C#

Question

I'm tyring to setup Git functionality in my application with NGit. The repository is an SSH authenticated one on BitBucket, that I am unable to authenticate for Git functionality like Push, Pull, Clone etc.

My code is as follows:

JschConfigSessionFactory:

public class NSessionFactory : JschConfigSessionFactory
{
    protected override void Configure(OpenSshConfig.Host hc, Session session)
    {
        session.SetConfig("StrictHostKeyChecking", "no");
    }

    protected override JSch CreateDefaultJSch(FS fs)
    {
        JSch defaultJSch = new JSch();
        defaultJSch.SetKnownHosts(@"<path>\known_hosts");
        defaultJSch.AddIdentity(@"<path>\id_rsa");
        return defaultJSch;
    }
}

TransportConfigCallback:

public class NTransportConfigCallBack : TransportConfigCallback
{
    public void Configure(Transport transport)
    {
        SshTransport sshTransport = (SshTransport)transport;
        sshTransport.SetSshSessionFactory(new NSessionFactory());
    }
}

Push command:

Git gitObj = NGit.Api.Git.Open(<path to git repo>);

PushCommand pshCmd = gitObj.Push();
pshCmd.SetRemote("ssh://git@stash.name.com:xxxx/repo.git");
pshCmd.SetTransportConfigCallback(new NTransportConfigCallBack());
pshCmd.Call();

Following exception on PushCommand.Call():

"TransportException: ssh://git@stash.name.com:xxxx/repo.git: Auth fail"

The BitBucket account already has the SSH key setup and everything works with other GIT tools.

At this point I have no idea what could be wrong, and I'd appreciate any pointers in the right direction.

Changing up the code as in the answer here produces the same exception.

Does your remote URL have the right format? It seems that for public BitBucket repositories it would be `ssh://git@bitbucket.org//repo.git`. Can you connect to the repository with CLI Git? — Rüdiger Herrmann, Jul 13 '17 at 04:55
The URL is correct, and I have already used the same to clone the repository. See here: http://imgur.com/a/JhW02 I'm using the same url in my code. Really don't think that's the problem :( — PhoenixDev, Jul 14 '17 at 07:34
It seems that your ssh key requires a passphrase, in this case, use `defaultJsch.addIdentity( "", "" )`. — Rüdiger Herrmann, Jul 14 '17 at 09:58

It seems that your SSH key requires a passphrase, in this case, use

defaultJsch.AddIdentity( "<path>", "<passphrase>" )
