Java .jar and .class de-compilation and recompilation if you are familiar with java it is too good but hover you must be have to know that how to write program in java.Java is an advanced language it is mostly used in network based application and for cross platform development the java application execution architecture is as follow Java code which are saved in .java file are compiled to .class file which basically execute on the JVM for distribution the .class files are packaged in .jar archives which also execute on the JVM so now as our binaries must be .class or .jar files so we have to work on those to reverse it the .class file have the name as that of .java and when the .class file is brought to JVM it frist start to execute main() function if it exists(in libraries there are no main() function) So our starting file in java files must be that one which have main.Now we know that .class is byte code executable on JVM files so we are going here to de-compile it to...

Software reverse engineering is the process of recovering a software code from its binary and making changes in it.the software companies like Microsoft,Adobe etc are trying to protect there software's against the Copying or illegal distribution.They provide the online activation process.The protection of there software are there legal right but still people are trying to remove these constraint and redistribute or copy it. The process is done by reverse engineering. This is illegal but upon they are good we know a lot of country in the world are said 3 rd world countries the people of those countries are poor and have right to use those new things in the world, which exists so they use reverse engineering process and get a way to use it. The Reverse engineering of software involves the study of software, which should be reversed there are some steps in reversing which are bellow. I. Study of Software II. Get information from Software III. De-compiling the Software if...
