X-package 6.4.0 破解

获取x-pack-core-6.4.0.jar

下载 elasticsearch
下载页面：https://www.elastic.co/downloads/elasticsearch

下载下来，解压压缩包，x-pack-core-6.4.0.jar 就位于 elasticsearch-6.4.0/modules/x-pack-core 目录下面

使用luyten反编译x-pack-core-6.4.0.jar

下载 luyten
下载页面：https://github.com/deathmarine/Luyten/releases

软件下载下来，打开软件，把x-pack-core-6.4.0.jar 丢进去，就能看到我们jar包的源代码了。
我们需要把2个文件提取出来进行修改。
org.elasticsearch.license.LicenseVerifier
org.elasticsearch.xpack.core.XPackBuild

1、修改LicenseVerifier
LicenseVerifier 中有两个静态方法，这就是验证授权文件是否有效的方法，我们把它修改为全部返回true.

package org.elasticsearch.license;

import java.nio.*;
import org.elasticsearch.common.bytes.*;
import java.util.*;
import java.security.*;
import org.elasticsearch.common.xcontent.*;
import org.apache.lucene.util.*;
import org.elasticsearch.core.internal.io.*;
import java.io.*;

public class LicenseVerifier
{
    public static boolean verifyLicense(final License license, final byte[] encryptedPublicKeyData) {
        return true;
    }

    public static boolean verifyLicense(final License license) {
        return true;
    }
}

2、修改XPackBuild
XPackBuild 中最后一个静态代码块中 try的部分全部删除，这部分会验证jar包是否被修改.

package org.elasticsearch.xpack.core;

import org.elasticsearch.common.io.*;
import java.net.*;
import org.elasticsearch.common.*;
import java.nio.file.*;
import java.io.*;
import java.util.jar.*;

public class XPackBuild
{
    public static final XPackBuild CURRENT;
    private String shortHash;
    private String date;

    @SuppressForbidden(reason = "looks up path of xpack.jar directly")
    static Path getElasticsearchCodebase() {
        final URL url = XPackBuild.class.getProtectionDomain().getCodeSource().getLocation();
        try {
            return PathUtils.get(url.toURI());
        }
        catch (URISyntaxException bogus) {
            throw new RuntimeException(bogus);
        }
    }

    XPackBuild(final String shortHash, final String date) {
        this.shortHash = shortHash;
        this.date = date;
    }

    public String shortHash() {
        return this.shortHash;
    }

    public String date() {
        return this.date;
    }

    static {
        final Path path = getElasticsearchCodebase();
        String shortHash = null;
        String date = null;
        Label_0157: {
            shortHash = "Unknown";
            date = "Unknown";
        }
        CURRENT = new XPackBuild(shortHash, date);
    }
}

编译修改后的java文件

javac -cp ".:./x-pack-core-6.3.2.jar:./elasticsearch-6.4.0/lib/*" LicenseVerifier.java
javac -cp ".:./x-pack-core-6.3.2.jar:./elasticsearch-6.4.0/lib/*" XPackBuild.java

需要注意的是，编译这两个文件的时候需要指定依赖包的位置如果你的位置和我的有区别，注意修改。

将编译好的class文件重新压回x-pack-core-6.4.0.jar

解压x-pack-core-6.4.0.jar 会得到一个 x-pack-core-6.4.0目录，按照其位置将编译好的2个 class文件放到我们目录里面，替换老的。

将修改过的 x-pack-core-6.4.0目录重新压成jar包。

jar -cvf x-pack-core-6.4.0_new.jar -C x-pack-core-6.4.0 .

导入授权文件

1、先从官网申请basic授权文件
https://license.elastic.co/registration

2、授权文件修改

{

   "uid": "6fb96d6b-938c-45ff-9ce7-6b53b39cd7dd",

   "type": "platinum", # 修改授权为白金版本

   "issue_date_in_millis": 1530489600000,

   "expiry_date_in_millis": 2855980923000, #修改到期时间为2060-07-02

   "max_nodes": 100,  # 修改最大节点数

   "issued_to": "xxxx",

   "issuer": "Web Form",

   "signature":"AAAAAwAAAA3PP60wKNtAvRmuCGdSAAABmC9ZN0hjZDBGYnVyRXpCOW5Bb3FjZDAxOWpSbTVoMVZwUzRxVk1PSmkxaktJRVl5MUYvUWh3bHZVUTllbXNPbzBUemtnbWpBbmlWRmRZb25KNFlBR2x0TXc2K2p1Y1VtMG1UQU9TRGZVSGRwaEJGUjE3bXd3LzRqZ05iLzRteWFNekdxRGpIYlFwYkJiNUs0U1hTVlJKNVlXekMrSlVUdFIvV0FNeWdOYnlESDc3MWhlY3hSQmdKSjJ2ZTcvYlBFOHhPQlV3ZHdDQ0tHcG5uOElCaDJ4K1hob29xSG85N0kvTWV3THhlQk9NL01V",

   "start_date_in_millis": 1530489600000

}

时间戳、时间转换

3.通过API接口上传
curl -u elastic:elastic -XPUT ‘http://es-ip:port/_xpack/license’ -H “Content-Type: application/json” -d @/tmp/license.json
