使用java类破解MyEclipse

今天在网上查资料的时候无意中发现使用java类破解MyEclipse的注册码问题。跟大家分享一下

1、建立JAVA Project，随便命名，只要符合规则就行

2、在刚刚建好的Project右击src，新建一个类，命名为MyEclipseGen，把.java里本来有的代码全部删掉，再把下面的代码复制到文件中。

import java.io.*;

public class MyEclipseGen {
    private static final String LL = "Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998 (http://www.loc.gov/copyright/legislation/dmca.pdf). Under section 1204 of the DMCA, penalties range up to a $500,000 fine or up to five years im*ment for a first offense. Think about it; pay for a license, avoid prosecution, and feel better about yourself.";

    public String getSerial(String userId, String licenseNum) {
        java.util.Calendar cal = java.util.Calendar.getInstance();
        cal.add(, );
        cal.add(, -);
        java.text.NumberFormat nf = new java.text.DecimalFormat("");
        licenseNum = nf.format(Integer.valueOf(licenseNum));
        String verTime = new StringBuilder("-")
                .append(new java.text.SimpleDateFormat("yyMMdd").format(cal
                        .getTime())).append("").toString();
        String type = "YE3MP-";
        String need = new StringBuilder(userId.substring(, )).append(type)
                .append("").append(licenseNum).append(verTime).toString();
        String dx = new StringBuilder(need).append(LL).append(userId)
                .toString();
        int suf = this.decode(dx);
        String code = new StringBuilder(need).append(String.valueOf(suf))
                .toString();
        return this.change(code);
    }

    private int decode(String s) {
        int i;
        char[] ac;
        int j;
        int k;
        i = ;
        ac = s.toCharArray();
        j = ;
        k = ac.length;
        while (j < k) {
            i = ( * i) + ac[j];
            j++;
        }
        return Math.abs(i);
    }

    private String change(String s) {
        byte[] abyte0;
        char[] ac;
        int i;
        int k;
        int j;
        abyte0 = s.getBytes();
        ac = new char[s.length()];
        i = ;
        k = abyte0.length;
        while (i < k) {
            j = abyte0[i];
            if ((j >= ) && (j <= )) {
                j = (((j - ) + ) % ) + ;
            } else if ((j >= ) && (j <= )) {
                j = (((j - ) + ) % ) + ;
            } else if ((j >= ) && (j <= )) {
                j = (((j - ) + ) % ) + ;
            }
            ac[i] = (char) j;
            i++;
        }
        return String.valueOf(ac);
    }

    public MyEclipseGen() {
        super();
    }

    public static void main(String[] args) {
        try {
            System.out.println("please input register name:");
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    System.in));
            String userId = null;
            userId = reader.readLine();
            MyEclipseGen myeclipsegen = new MyEclipseGen();
            String res = myeclipsegen.getSerial(userId, "");
            System.out.println("Serial:" + res);
            reader.readLine();
        } catch (IOException ex) {
        }
    }
}

3、运行，按照提示输入一串字符，建议取名字的首字母，然后回车，会出现一串注册码，然后复制注册码。

如图

3-1：代表注册码的Subscriber

3-2:是你的Code

4、然后MyEclipse --> Subscription Information，按提示第一行输入你刚刚输入的字符串，第二行粘贴注册码即可。

如果成功的话应该会发现如下提示，点击finish结束，恭喜你成功啦！！

我试过了，可以用的！
