Tamir.SharpSsh Could not load file or assembly 'DiffieHellman

private void OVConnection()
{
    try {
        //Create a new JSch instance
        JSch jsch = new JSch();

        this.Dispatcher.BeginInvoke(new Action<Status>(DisplayStatus), Status.Connecting);
        //Create a new SSH session
        string host = "url"; //url
        string user = "***"; //ssh username
        string pass = "*******"; //ssh password
        int sshPort = 22; //ssh port
        int rPort = 3306;
        int lPort = 3306;

        int port = Convert.ToInt32(sshPort);

        session = jsch.getSession(user, host, port);
        session.setHost(host);
        session.setPassword(pass);

        UserInfo ui = new MyUserInfo();
        session.setUserInfo(ui);

        session.connect();

        //Set port forwarding on the opened session
        session.setPortForwardingL(lPort, "localhost", rPort);

        if (session.isConnected()) {
            MyDatabase();
        }
    }
    catch (Exception ex) {
        MessageBox.Show(ex.Message);
        this.Dispatcher.BeginInvoke(new Action<Status>(DisplayStatus), Status.NotConnected);
    }
}

I get:

I can not figure out why.

private static void CopyfileToSFTP(string filePath)
        {
            try
            {
                
                log.Info("Started Copying file to sftp Server...");
                Tamir.SharpSsh.Sftp sftp = new Tamir.SharpSsh.Sftp(ConfigurationManager.AppSettings.Get("SFTPHost"), ConfigurationManager.AppSettings.Get("SFTPUserName"), ConfigurationManager.AppSettings.Get("SFTPPassword"));
                log.Info("sftp Server connecting");
                sftp.Connect(Convert.ToInt32(ConfigurationManager.AppSettings.Get("SFTPPort")));

                log.Info("sftp Server connected");
                sftp.Put(filePath, ConfigurationManager.AppSettings["SFTPFileLocationPath"]);
                log.Info("sftp Server file pushed to location");
                sftp.Close();

            }
            catch (Exception e)
            {
                log.Info("Error : " + e.Message);
            }

            log.Info("SFTP server file writing Done..");

        }

I had the same error in production on this line sftp.Put(filePath, ConfigurationManager.AppSettings["SFTPFileLocationPath"]);

By just copying DiffieHellman.dll and Org.Mentalis.Security.dll to deployed folder solved the issue.

I had the same error and was able to resolve it by adding this NuGet package from Mentalis to my project references.

Make sure you have the NuGet package manager installed, first. After installing it, I did this:

Right-click References > Manage nuget packages > search for DiffieHellman > Install

This worked for me.
