如您所见,服务器提供以下密码:
信息:kex:服务器:aes256-cbc,aes192-cbc
但是JSch仅接受以下内容:
信息:kex:客户端:aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc
没有通用的密码可供选择。
请注意,JSch确实支持aes256-cbc和aes192-cbc,但是需要JCE(Java密码学扩展)来允许它们。
您可能没有JCE,因此这些密码不可用。这就是为什么
信息:aes256-cbc不可用。
下载Java密码学扩展(JCE)无限强度管辖权策略文件8(或其他版本,如果未使用JDK 1.8)。

我解决了将库jsch-0.1.27.jar更新为jsch-0.1.54.jar的问题。
最后,在代码中,您应该编写如下代码:
your Method {
session.setConfig("StrictHostKeyChecking", "no");
// That solve the problem.
}
如果您需要此Java版本,则此代码可在Java 1.5或更高版本中使用。
