ProGuard IntroductionProGuard is a well-known open-source project on SourceForge. Official Website: http://proguard.sourceforge.net /. Java bytecode is generally very easy to decompile. To protect the Java source code, we often confuse compiled class files. ProGuard is mainly used for obfuscation. Of course, it can also reduce the size and optimize the bytecode, but those are secondary features for us. The official ProGuard article is introduced as fo

Today, I am launching a piece of Obfuscated javascript code, because the source code is lost... I was planning to get the code at the js engine level and found that it was not necessary at all. Manual decryption is much simpler than imagined. It took less than half an hour to complete the decryption. The most important part of JavaScript obfuscation: L eval, document. write, vbs execute, execScript, and other functions that can run JavaScript L unesca

What is code obfuscation Java is a cross-platform, interpreted language in which Java source code is compiled into an intermediate "bytecode" stored in a class file. Because of the cross-platform requirements, Java bytecode contains a lot of source code information, such as variable name, method name, and through these names to access variables and methods, these symbols with a lot of semantic information, it is easy to decompile the Java source code.

Due to the proliferation of various decompilation tools, Android programmers can only manually add proguard Before Version 2.3 to achieve code obfuscation. Proguard is a Java code obfuscation tool. In SDK 2.3, we can see that a proguard folder is added under Android-SDK-Windows/tools /. Google has put proguard Technology in the android SDK, so that code obfuscation
