aspose-words-19.1-jdk16 crack记录

涉及到的工具

JByteMod-1.8.2
luyten-0.5.3
javassist-3.24.1-GA

crack思路

从aspose-words-java.jar使用，可以反推License认证过程

License.java -> zzZLJ.java 

InputStream is = com.aspose.words.Document.class
                    .getResourceAsStream("/com.aspose.words.lic_2999.xml");
            License asposeLicense = new License();
            asposeLicense.setLicense(is);
            System.out.println("Aspose isLicensed: " + asposeLicense.isLicensed());

crack过程

1. 先用JByteMod清除掉zzZ(final Node node, final Node node2, final String s)方法体中的内容

2. 使用javassist动态生成新class

引入javassist依赖

<dependency>      
    <dependency>
      <groupId>org.javassist</groupId>
      <artifactId>javassist</artifactId>
      <version>3.24.1-GA</version>
    </dependency>

public class AsposeWordsCrack191 {

    public static void changeMethod() throws Exception {
        System.out.println("开始破解！");
        ClassPool.getDefault().insertClassPath("d:\\aspose-words-19.1-jdk16.jar");

        CtClass c2 = ClassPool.getDefault()
                .getCtClass("com.aspose.words.zzZLJ");
        CtMethod[] ms = c2.getDeclaredMethods();
        for (CtMethod c : ms) {
            System.out.println("method name:" + c.getName() + "() ,Parameter:");
            CtClass[] ps = c.getParameterTypes();
            for (CtClass cx : ps) {
                System.out.println("\t" + cx.getName());
            }

            if (c.getName().equals("zzZ") && ps.length == 3
                    && ps[0].getName().equals("org.w3c.dom.Node")
                    && ps[1].getName().equals("org.w3c.dom.Node")
                    && ps[2].getName().equals("java.lang.String")) {
                System.err.println("find it!!!!!!!!!!!!!!!!!");
                c.insertBefore("{return;}");
            }

            if (c.getName().equals("zzZI1")) {
                System.err.println("find it!!!!!!!!!!!!!!!!!" + c.getName());
                c.insertBefore("{return 1;}");
            }

            if (c.getName().equals("zzZI0")) {
                System.err.println("find it!!!!!!!!!!!!!!!!!" + c.getName());
                c.insertBefore("{return 1;}");
            }

        }
        //输出到当前目录下
        c2.writeFile();
    }

    public static void main(String[] args) {
        try {
            AsposeWordsCrack191.changeMethod();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
} 

生成一个zzZLJ.class

3. 替换原zzZLJ.class

4. 新旧zzZLJ类不同

5. 删除META-INF目录，增加认证文件com.aspose.words.lic_2999.xml

认证文件com.aspose.words.lic_2999.xml

<License>
  <Data>
    <Products>
      <Product>Aspose.Words for Java</Product>
    </Products>
    <EditionType>Enterprise</EditionType>
    <SubscriptionExpiry>29991231</SubscriptionExpiry>
    <LicenseExpiry>29991231</LicenseExpiry>
    <SerialNumber>---</SerialNumber>
  </Data>
  <Signature>---</Signature>
</License>

测试新crack.jar

可以用aspose-words-19.1-crack.jar命名，或直接替换aspose-words-19.1-jdk16.jar

<dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-words</artifactId>
            <version>19.1</version>
            <classifier>crack</classifier>
        </dependency>

在本地maven目录下

2. 测试代码

public class CrackSample {

    public static void main(String[] args) throws Exception {
        String baseDir = "D:\\testAspose\\";
        doc2pdf(baseDir + "工程文档.docx", baseDir + "工程文档.pdf");
    }

    /**
     * 使用Aspose.Words前都要验证License 若不验证则转化出的pdf文档有水印
     * @return
     * @throws Exception
     */
    public static boolean checkLicense() throws Exception {
        boolean result = false;
        try {
            InputStream is = com.aspose.words.Document.class
                    .getResourceAsStream("/com.aspose.words.lic_2999.xml");
            License asposeLicense = new License();
            asposeLicense.setLicense(is);
            System.out.println("Aspose isLicensed: " + asposeLicense.isLicensed());
            result = true;
            is.close();
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
        return result;
    }

    public static void doc2pdf(String inPath, String outPath) throws Exception {
        // 验证License 若不验证则转化出的pdf文档有水印
        if (!checkLicense()) {
            throw new Exception("com.aspose.words lic ERROR!");
        }

        System.out.println(inPath + " -> " + outPath);

        try {
            long old = System.currentTimeMillis();
            File file = new File(outPath);
            FileOutputStream os = new FileOutputStream(file);
            Document doc = new Document(inPath); // word文档
            // 支持RTF HTML,OpenDocument, PDF,EPUB, XPS转换
            doc.save(os, SaveFormat.PDF);
            long now = System.currentTimeMillis();
            System.out.println("convert OK! " + ((now - old) / 1000.0) + "秒");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

导出的文档没有水印标志了
