This wonderful tool will tell you about the execution flow along with other details. The interface of the application is very neat and clean, you need to open the executable file and start the application. Portable OllyDbg 2.0 Reviewĭevelopers sometimes read the code to understand the application but sometimes when the code is not present and you only have the executable files and DLLs then OllyDbg is the most reliable application which allows you to debug applications at runtime.

We have only the executable version of that specific application, which when disassembled and the code is analyzed is in fact, a tedious task in the context of Reverse Engineering.Download standalone portable version of OllyDbg 2.0 for Windows 32-bit and 64-bit. Portable OllyDbg 2.0 is a powerful assembler analyzing debugger for applications to analyze and modify the execution flow of programs. In simple terms, what we are implying is that we don't have the actual source code and development environment indeed. This time, we are presented with an application that the origin is unknown altogether. They can only be disassembled into typical assembly language code that is very difficult to scrutinize.

This is not possible in the case of a C/C++ binary. NET binary because they can be disassembled into their original source code. NET applications earlier however, it is relatively easy to do it in the context of a.

Although there are many tools that can do the same thing the beauty behind OllyDbg is that it is simple to operate and freely available. The objective of this paper is to show how to crack an executable without seeing its source code, using the OllyDbg tool instead.
