我正在开发 java 程序以通过 ssh 与 Windows 服务器连接。为此，我在 java 上使用了 jcraft。ssh 服务器是 copSSH。实现抛出
错误：com.jcraft.jsch.JSchException：算法协商失败
java上的错误。同时它显示
致命：无法与 192.168.28.111 协商：找不到匹配的密码。他们的报价：aes128-cbc,3des-cbc,blowfish-cbc [preauth]
在 CopSSH 上。
Java代码块
public void sshExecPassword(String host, String USERNAME, String PASSWORD, String command) {
App objApp = new App();
int port = 22;
try {
/**
* Create a new Jsch object This object will execute shell commands
* or scripts on server
*/
JSch jsch = new JSch();
/*
* Open a new session, with your username, host and port Set the
* password and call connect. session.connect() opens a new
* connection to remote SSH server. Once the connection is
* established, you can initiate a new channel. this channel is
* needed to connect to remotely execution program
*/
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
Session session = jsch.getSession(USERNAME, host, port);
session.setConfig(config);
session.setPassword(PASSWORD);
session.connect();
// create the excution channel over the session
ChannelExec channelExec = (ChannelExec) session.openChannel("exec");
// Gets an InputStream for this channel. All data arriving in as
// messages from the remote side can be read from this stream.

String str = command;
channelExec.setCommand(str);
channelExec.connect();

int exitStatus = channelExec.getExitStatus();
// Safely disconnect channel and disconnect session. If not done
// then it may cause resource leak
channelExec.disconnect();
session.disconnect();

和 CopSSH 主机以下版本
OpenSSH_7.1p2，OpenSSL 1.0.2e 2015 年 12 月 3 日
任何人都可以建议修复它吗？
