First, you do not need to apologize for being a newbie. It is an EXCELLENT dynamic debugger for x86 targets in Windows.
Sorry I'm a noob.
For the hash generated from the password we entered, when I first found the routine, I noticed that there is a hard-coded string that is 32 hex characters in length. Before beginning, I do recommend that you have a mild understanding of programming and the ability to read assembly, however. I want to dig deeper into reversing, is it possible for x64dbg to output the disassembly view to a .asm file, if can is there a way to automate the whole process. Welcome to part 2 of the Bypassing Protections series. For different platforms & languages in which software is written, there are different types of debuggers. If this does not work, sometimes you just need to be patient and step through the subroutines until you see the values you are looking for. Then, I load the dll into x64dbg.

In this part, we will be looking at an application which uses online activation to v... Hello and welcome to this new series called Bypassing Protections.
In order to remove bugs from a program or to modify an app with or without having the source code, a process called debugging is used.
Having a decent knowledge of Stack is very useful while debugging. Introduction¶. I was wondering what further resources you would point to to go ahead with the learning process ?I currently have the great old video course by lena101, it's great but kind of a little advanced (and for the old Olly mainly).Do you know any reversing courses worth trying? For different platforms & languages in which software is written, there are different types of debuggers. You can also compile x64dbg yourself with a few easy steps!
In case of we know the "Offset" value how can we locate to the exact address? Debugging is usually done under 2 situations- When source code is available & when source code is not available. There are many features available and a comprehensive plugin system to add your own. A few things that can possibly help with DLLs is to search for names in current module and search for any telltale names that can help you. It is impossible to reverse an md5 hash to get the original value, so either bruteforce or comparing it to the values in a massive online database is the only option.
x64dbg uses C++ and Qt to quickly add new features.
It is just like ollydbg 64 which can be used for dynamic debugging & malware analysis.

A Reverse Engineering blog dedicated to unraveling the mysteries of reverse engineering. So what would you do if you can't find the string refrence in the main module?
It is just like Olly debugger meant for windows 8, 8.1, 10 versions. The stack is space in memory in which is used to temporarily used to store data.
There a several types of hashes which have 32 characters, or 16 bytes when in binary form, such as md2, md4, md5, and maybe others. I wish I could try but… your targets happen to be chrome extensions, too bad ! So you could find out which algorithm generates it.
Based on architecture, there are 2 types of processors(nowadays)- 32 bit & 64 bit. I'm stuck and don't know anyone with skills and I just lost 4 nights on this and I wanna shoot myself, and my wife wants to kill me as well :) And I think it's easy for someone like you, and this kind of problem is always killing me with olly, when I'm searching for string in variable that is generated in code..I tried every approach I could find on internet tutorials, memory breakpoints, I just have no luck.I don't want to write target name publically.Anyway, thank you for your blog, I found it usefull cos I didn't know how to save changed file in x64dbg :). Never give up. Thanks a lot.But well could ya do some minor updated on the Setting/Misc dialog?It now has two new fields 'Symbol Store' and 'Symbol Path'.At the moment it's proper use is a little unclear to me.
