here<\/a>.<\/p>\nBelieve me or not, I would have given this code (new version) under BSD. I really wanted to. A proof is that diStorm64 was BSD so far, and\u00a0still is, however it is deprecated.\u00a0But I don’t see a good end for BSD. Let me explain. It’s very permissive, everybody can use it and I like it more than GPL for that reason, truely.\u00a0Why after all I decided on releasing diStorm in a GPL license, and not even LGPL? That’s a good question and I will answer this by telling you my story and more.<\/p>\n
I began this project for pure fun and challenge of decoding x86, back in mid\u00a02003 already. Soon enough I got some basic framework that could accept a stream, look in some data structure and fetch an instruction, then decode the operands. Sounds easy, right? Because it is easy. But that was only for integer instructions. After a few months I added FPU support. This is where I started to hate the x86 machine code, really. It’s a pain in the arse.\u00a0Only at that time I started to look around and to see what other (disassembler) libraries we got on the Internet, it was already 2004, and I still enjoyed coding diStorm for the fun and sport of it, 100% from scratch, always. I knew from day\u00a0one that I am going to make it an open source project. And yet, it wasn’t so useful, there were better disassemblers out there. I’m talking about binary stream diassemblers, mind you, not the GUI wrapped ones, with high level features. Anyway, diStorm wasn’t any special yet. Therefore I had to work hard,\u00a0in my free time, no complaints ever. And added all those SSE instructions set. Like 5 sets eventually were added to diStorm, in addition to new sets every now and then in other computing fields. Honestly, I doubt people use diStorm for SSE,\u00a0but you never know. Besides the goal of diStorm was to be a complete product, top quality and optimized, and I achieved them all within time. diStorm was opened source in the beginning of 2006. A few months later I added AMD64 support, and then diStorm was the first open source disassembler library to support it.<\/p>\n
All the while I got lots of emails about diStorm. Some were about asking help of how to use it, some were about defects in specific isntructions, etc. And even two critical bugs, one is code regression that I put a bug in the code accidentally, and the other was some memory leak in the Python module, which I happened to fix before already.<\/p>\n
The most appreciated work from the community was about the sample projects. People helped me with the code to make it more useful,\u00a0and better code for each platform\u00a0(there are Win32 and Linux separated projects). But never anything about diStorm’s code itself. Maybe the project is too complex. Maybe there was no need, overall it was stable and mature. I don’t know.<\/p>\n
Since 2005 I got more than 50,000 downloads of the variants of diStorm (the sample projects, the full source code, the library, the Python modules, etc). It is a lot, like 10K a year. Don’t forget that after all it’s a mere\u00a0disassembler, not some crazy application, and it’s even a library, so only developers can use it. Though later I\u00a0added the flat disassembler project compiled and which can be downloaded in a binary form. And what we learn from this? Nothing, nada! You can never trust statistics as this, and it doesn’t mean much. Cause there are new releases and the same person can download the project a few times within some time, to get the latest version, etc. So I can’t have any info about how many people\/companies use it around the world.<\/p>\n
My own goal was to make diStorm the best disassembler out there. Only you can judge. I know what it’s worth.<\/p>\n
Sometimes I had the doubts about this issue. And it gave me the inspiration to go on and bring the next generation disassembler library to the world, one that afterwards I can retire, in a way, and finally start to enjoy the fruits of my hard work with coding code analysis tools myself in the future. About time, yey, no more excuses, no more stupid string parsing, totally efficient.<\/p>\n
I see many people complain about the general status of tools in the Reverse Engineering\u00a0field. Not many people open their code. And the rest make money out of it. And I want to make a better community in this field. I really tried to do so, but without success. People that use diStorm either only use it as is, and they won’t open their code, because they want to keep their precious knowledge to themselves, or sell it for money. That’s legitimate. You work, you get money. \u00a0And it also gives the opportunity for tools to exist, otherwise they won’t be there at all. But I think we can do better. I am doing better myself this way, I belive so and therefore I open the code in GPL. GPL is ugly and the only reason I am for it is because I want the community to help me with this project and the coming one. Ohhhh, you will love the next project. It’s not a library anymore but a whole studio…dreams come true. I make them coming true on my end, but I need help. For crying out loud.<\/p>\n
I, hereby, am asking from the community, the people out there, that do this stuff for fun or profit to help, to contribute back to the community<\/em>. I can’t do it all myself, it will take years. Though I am willing to do it myself, and that’s what I do. But then WHAT FOR?! So some companies can enjoy my work and get money on my expense? NO THANKS.<\/p>\nCommunity, Community, Community, this is key, what the whole issue is about. You are saying you need open source tools, no problem, but share. Let’s do it together. Parsing strings is not the way. Finally we got a good weapon and let’s build a framework on top of it. We got Olly, we got WinDbg, and we got IDA. None of them is opened source. Each has a clear win in its niche. I think there is a room, a NEED,\u00a0for something new, free and open source. If I am not going to get help this time, I am not going to open source the next project, because it’s pointless and by now you should know exactly why.<\/p>\n
You know what, maybe it’s all my fault. Maybe diStorm’s code is TOO complex. (What do you expect though?). Maybe the stupid and ugly diStorm’s page is not easy to track. Otherwise why I see someone who spent a few hours taking a disassembler out of a bigger project and make it work for Windows kernel, while you can do that in diStorm in two clicks?<\/p>\n
Maybe nobody gives a f@ck about it, probably, just a stupid disassembler. But no more. This is the time to make a change, a big one.\u00a0It might be a disassembler, or anything else, but it just shows the attitude of the community.And don’t kid yourself, everybody looks for code analysis stuff, or eventually write them up on their own. C’est tout. Mailling list or not, if we are not going to help each other and only complain that there are not enough open source projects in the RE field, nothing good is gonna happen.<\/p>\n
GOOD LUCK!<\/p>\n
