    I am trying to do a sftp using JSch but encounters some errors "com.jcraft.jsch.JSchException: The cipher 'aes256-cbc' is required, but it is not available." Below is the code I used. Is there anything I missed out?

    JSch jsch = new JSch();
    Session session = null;
    try {
        jsch.addIdentity("C:\\1234.ppk", "password");
    
        session = jsch.getSession("user", "54.251.35.60", 22);
        session.setConfig("StrictHostKeyChecking", "no");
        session.connect();
    
        Channel channel = session.openChannel("sftp");
        channel.connect();
        ChannelSftp sftpChannel = (ChannelSftp) channel;
        sftpChannel.put("C:\\Users\\1234.ppk", "/home/user/12345678888.ppk");
        sftpChannel.exit();
        session.disconnect();
    } catch (JSchException e) {
        e.printStackTrace();  
    } catch (SftpException e) {
        e.printStackTrace();
    }
