Java字串混淆器功能
Java字串混淆器改變Java字串後,可以保護原始碼,並減少使用逆向工程的駭客和競爭對手。 Zelix KlassMaster Java字串模糊處理器,自1997年發布以來不斷發展,以保持在模糊技術的先鋒地位。
先進的Java字串保護
Zelix KlassMaster提供第二代模糊處理技術,其獨特的加密技術加入Java字節碼保護。其擁有第一代的Zelix KlassMaster全方位的混亂處理技術,再加上擁有高度保護的Java字節碼混淆器,因此Zelix KlassMaster在本領域是無與倫比的
Java字串尺寸極小化
Zelix KlassMaster的名稱混淆功能,可以減少封包、分類字串和方法的大小。 Zelix KlassMaster的修剪功能,進一步自動刪除未曾使用的分類、字串和方法,以減少字串的大小。
功能強大且易於使用
Zelix KlassMaster提供易於使用的用戶界面,簡化初學者的學習時間。功能強大且直觀的ZKM腳本,使您可以自動模糊處理在您所構建的週期。Zelix KlassMaster還提供了一個工具界面,讓您可以執行ZKM腳本的Apache Ant構建工具。
Advanced Java bytecode protection
In addition to its excellent first generation Name Obfuscation functionality, Zelix KlassMaster™ provides the following added Java bytecode protection:
- Second generation Flow Obfuscation technology.
- Innovative String Encryption technology. (We invented it.)
- Robust Reference Obfuscation technology which allows you to selectively obscure field accesses or method calls.
- Unique Method Parameter Changing technology which dramatically hardens our String Encryption and Reference Obfuscation functionality against being reversed.
- An additional, enhanced, third generation Flow Obfuscation technology based upon the Method Parameter Changing functionality that can be used with or instead of our classic Flow Obfuscation.
- Innovative Method Parameter Obfuscation technology which allows you obscure method parameter lists. (Again we invented it.)
- Unique Exception Obfuscation technology.
It is Zelix KlassMaster's comprehensive Flow Obfuscation, String Encryption and Reference Obfuscation technologies that made it the first, true second generation, heavy duty Java obfuscator. It is still unmatched.
Maximized Java bytecode size reduction
As well as protecting your Java bytecode from being decompiled to comprehensible source code, Zelix KlassMaster's Name Obfuscation functionality reduces your bytecode size by reducing the size of your package, class, field and method names. Zelix KlassMaster's Trim functionality further reduces your bytecode size by removing unused classes, fields and methods.
Powerful but easy to use
Zelix KlassMaster™ provides a number of interfaces. Its easy to use GUI interface eases the learning curve for new starters. However, it is the powerful yet intuitive ZKM Script language interface that allows you to automate the obfuscation process and integrate it into your build cycle. Zelix KlassMaster™ also provides a Build Tool Interface to allow you to execute ZKM Scripts from within a build tool such as Apache Ant.
Zelix KlassMaster's unique AutoReflection™ technology solves the Java Reflection API call problem by automatically handling complicated Java Reflection API calls. This can dramatically reduce the amount of work that you have to do if you are obfuscating classes containing complex or obscure Reflection API calls.
Zelix KlassMaster's Smart Save™ technology makes the Java obfuscation process easier by simplifying the handling of JAR, resource and Enterprise Java Beans deployment descriptor files. Zelix KlassMaster's default name exclusions provide automatic support for Serialization, RMI & JavaBeans and support for Java ME & JEE applications. Also, it supports Incremental Obfuscation by ensuring consistent renaming of objects and consistent flow obfuscation across your releases.
Finally, Zelix KlassMaster™ helps you debug your beta releases with its unique Line Number Scrambling technology. This technology allows you to determine real line numbers from stack traces reported by your beta test customers without reducing the level of your code protection. It can save your developers weeks of guess work. Zelix KlassMaster™ also provides the GUI Stack Trace Translate tool to make deciphering obfuscated stack traces effortless.
What do you need to run Zelix KlassMaster™?
Zelix KlassMaster™ is written entirely in Java 8 (i.e. JDK 1.8) and technically should run on any platform that supports a Java 8 or better Virtual Machine. However, note that Zelix KlassMaster™ version 10 or better requires a recent version of a Java 8 JVM or better to run. If you use an Oracle JVM earlier than 1.8.0_152 then you may get a JVM crash due to HotSpot bugs. Also note that Zelix KlassMaster™ version 21 currently may not run successfully on older versions (e.g. pre-Aug 2020) of the Eclipse OpenJ9 JVM due to a JVM bug.
More generally, differences in the file systems and GUIs can also cause problems. Further, Zelix KlassMaster's flow obfuscation technology can expose bugs in some Just in Time (JIT) compilers.
