带有PuTTYUserKeyFile和密码短语的java Apache SSHD客户端会话

Question

我尝试使用ApacheSSHD和Putty用户密钥和密码短语创建SSHEXEC通道。 但我不知道如何将它们添加为会话标识

我们公司用密码阻止了ssh连接（一些安全问题），我需要用这种方式建立连接

我们的ppk文件是这样的：

PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc
Comment: imported-openssh-key
Public-Lines: 12
.
.
.
Private-Lines: 28
.
.
.

致以最良好的祝愿

    SshClient sshClient = SshClient.setUpDefaultClient();
    sshClient.start();

    int defaultTimeout = 5000;
    File ppk = new File("path/to/file.ppk");
    String passphrase = "passphrase";

    try (ClientSession session = sshClient.connect("root", "192.168.72.128", 22).verify(defaultTimeout)
            .getSession()) {

        // here, how i add ppk file and passphrase to session ?

        session.auth().verify(defaultTimeout);
        
        ChannelExec channelExec;
        int exitStatus;
        ByteArrayOutputStream responseStream;
        ByteArrayOutputStream errorStream;

        String command = "ls -al";
        String error;
        String respond;

        // to execute remote commands
        try {

            responseStream = new ByteArrayOutputStream();
            errorStream = new ByteArrayOutputStream();

            channelExec = session.createExecChannel(command);

            channelExec.setOut(responseStream);
            channelExec.setErr(errorStream);

            try {

                channelExec.open().verify(defaultTimeout);

                channelExec.waitFor(EnumSet.of(ClientChannelEvent.CLOSED),
                        TimeUnit.MILLISECONDS.toMillis(defaultTimeout));

                exitStatus = channelExec.getExitStatus();

                System.out.println("Exit Status: " + exitStatus);

                error = new String(errorStream.toByteArray());

                if (!error.isEmpty()) {
                    throw new Exception(error);
                }

                respond = responseStream.toString();

                System.out.println(respond);

            } finally {
                channelExec.close(false);
            }
        } catch (Exception e) {

            e.printStackTrace();
        }
    }

    sshClient.stop();

对于JSch，我使用addIdentity（）函数完成了以下操作：

JSch jsch = new JSch();
File ppk = new File("path/to/file.ppk");
String passphrase = "passphrase";

Session session = jsch.getSession("user", "ip", 22);

jsch.addIdentity(ppk.getAbsolutePath(), passphrase);
