Java 如何将id_rsa.pub文件与JSch一起使用

使用JSch（）连接远程SFTP服务器时遇到问题。除了id\u rsa.pub文件和主机名以及主机ip地址之外，我没有任何要连接的远程服务器的访问权限或信息。并且该文件中的密钥在远程服务器中注册为授权密钥。因为我能够从shell登录到远程服务器

sftp -o BindAddress=SOME_IP_ADDRRESS myUserName@HOST_IP_ADDR

工作正常。但是当我用JSch做同样的尝试时，它不起作用。我所做的是：

我已经使用ssh-keygen从id_rsa.pub文件中可用的公钥创建了一个私钥

公钥格式为

ssh rsa AA..=someuser@something.com

我从keygen生成的私钥如下

-----开始RSA私钥-----

-----结束RSA私钥-----

我正在将此私钥文件与我的

session.addIdentity（私钥文件路径）一起使用

但它给了auth_失败一个例外，我做错什么了吗

代码是：

/* KEY_FILE_NAME = is a file with rsa public key */
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource(KEY_FILE_NAME).getFile());
JSch jsch = new JSch();
jsch.addIdentity(file.getAbsolutePath());
Properties hash = new Properties();
hash.put("StrictHostKeyChecking", "no");
logger.debug("SSh Server Host name >>" + SSH_SERVER_HOST_NAME + " || User Name >>" +  SSH_SERVER_USER_NAME);

session = jsch.getSession(SSH_SERVER_USER_NAME, SSH_SERVER_HOST_NAME);
UserInfo ui = new MyUserInfo();
session.setUserInfo(ui);
session.setConfig(hash);
session.setPort(22);
session.setTimeout(45000);
session.setSocketFactory(new SocketFactory() 
{
    InputStream in = null;
    OutputStream out = null;

    public InputStream getInputStream(Socket socket) throws IOException 
    {
        if (in == null)
            in = socket.getInputStream();
        return in;
    }

    public OutputStream getOutputStream(Socket socket) throws IOException 
    {
        if (out == null)
            out = socket.getOutputStream();
        return out;
    }

    public Socket createSocket(String host, int port) throws IOException, UnknownHostException 
    {
       // The IP Addresses are changed ....
       // using the original IP in my code
        byte[] remoteIpAddr = new byte[] { (byte) 11,(byte) 11, 11, 11 }; 
        byte[] localIpAddr = new byte[] { 55, 55, 55, 55 };

        InetAddress remoteIp = InetAddress.getByAddress(remoteIpAddr);
        InetAddress localIp = InetAddress.getByAddress(localIpAddr);

        logger.debug("remoteIp >>" + remoteIp.toString());
        logger.debug("localIp >>" + localIp.toString());
        Socket socket = new Socket(remoteIp, 22, localIp, 0);
        logger.debug("socket created >> " + socket.toString());
        return socket;
    }
});
session.connect();

请帮助，我做错了什么…
如何在命令行
ssh
中使用密钥？您是如何“从公钥创建私钥”的？马丁：非常感谢你的帮助，现在我的代码运行得很好。。我犯的错误是使用了错误的私钥文件。前面的代码工作正常。只需更改密钥内容并将私钥文件名从id_rsa.pub更改为id_rsa.OK，然后请删除此问题。@arpanda您是从公钥创建私钥的吗？怎么会？应该是相反的。
