first of all, i am really a newbie, never done anything like this before. On to the topic... i have an application that only will run with a dongle. this app have two levels of security 1. licence file (encryted) (feature lock) 2. dongle (usb).

the dongle has a daemon where it detect the dongle (duh.) and the only thing the app does is check with the daemon wherether there is a dongle connected or not. so that only suggest that i only need to patch the daemon so that it say its connected even without the dongle. that might be the easy part.

now the licence file is a whole diffrent story; during installation it ask for a key file that enable the type of software to be install. and after that a key file to enter registration name. both the keys have specific file name.

i need help in patching the daemon and enable all key and and registration name key generator.

so, show us what work you have already done (read your signature), this isnt a crack request forum

Go to the link to CrackZ's site at the bottom of the page - download everything you can and read.....read.....read... Then come back and we will help all we can.

i have found all the key files in a zip called pass_win.zip. the problem here is that it is passwod lock. i have tried brute force up to 7 characters but to no avail. is there any other way than plaintext coz i have no plaintext to compare with.

Got Cray?

Or a computer to dedicate to brute force for a couple of weeks? To my knowledge that's your only avenue, and if it's not all plaintext you're in for a long wait, but just in case try dictionary instead of plaintext first.

Or follow my first suggestion and Reverse it.

Also give a search to Mike's (The Moderator of the Crypto Board) approach to crack .zip files encryption/password.

how do i reverse it???

Do you have the slightest idea about what you are doing? To me, it looks like this:

"Well, I got this hammer and a welding torch, so I thought I'd just build a porsche from the scrap metal I just snagged. So how can I do it? Help!"

*sigh*

Probably you won't even understand it.

You might want to check out lastbit software - claims to findzip pwd very fast, but I think that the physics just don't support the claim.

You reverse it by finding what you need in the app itself - I'll say it again - scroll to the bottom of the page - look for the word "CrackZ" and double click it - download everything you can find that applies and set aside a few days for reading and a week or two for doing what you want to do - after READING and TRYING a while come back and we'll get you the rest of the way, just be prepared to explain what you've learned and done - this is not a site that teaches you how to crack an app. we help you learn to reverse a protection.

SiGiNT

ok will do just that....
thanks

well if i were to put it nicely, it will be like this...

yes i have a hammer with a welding torch next to me, and i thought i would just build a porche from the scrap metal i snagged with out the industries knowledge. but how would i do it.... well i guess that is what this forum for... as a guidepost on where to start looking and what to learn.... and as i mention earlier i have never done cracking before ( complete inexperiece) (newb).

and yes probably smart people like you who ran before you walk would not understand.

as requested by hosiminh, (by the way, your inbox is full)

here is the link to the zip file http://If.I.try.this.again/you.can.oh.so/ban.my.ass

The people here did not run before they could walk. At best they had a very rapid learning rate. They do, however, recognize someone trying to run before they have even learned how to crawl. And just about nobody around here cares for people who just want to learn how to crack a specific app - what you might be able to get help with, and what people might care to teach, is how to reverse and crack apps in general. But there have been so many newbies who thought they were entitled to every bit of help (extending so far as to readymade solutions) that the people here have become tired. Yours is just another request in a long line of "I wanna do this, show me how to do it". No reason why anyone here should care.
If you want help building a fast car, get started and when you get stuck, ask for help. If you can't even get started, quit while you're ahead or get a fucking brain, don't come here whining.

i have a encrypted key file, (*.dat type) how do i know what kind of encryption it uses and what i need to know to decrypt it.

First read all you can find about encryption. When you're done with that (approx. around 2010), come back here
Being serious: Many encryption methods have certain footprints. I remember a plugin for PEiD which is capable of identifying potential standard encryption methods. But all this will help you little.

The main thing is learning how to monitor your target and understanding what's going on. You will understand (hopefully) that everything that is encrypted needs to be decrypted for proper usage. So the trick will be intercepting the decryption process and storing the decrypted data. For whatever future purpose.

You will only learn this by acquiring the needed skills. This can be done by lots and lots of practical work, read tutorials and try to understand the ideas behind. Many people fail to realize that tutorials and not step-by-step guides on how to crack a particular target, instead they convey basic ideas and methods how to tackle certain problems. Ofcourse this needs some good knowledge of the inner workings of your machine.

A little example:

Many older tutorials suggest using breakpoints on a thing called _hmemcpy (IIRC, don't bug me for misspelling) which was used to copy blocks of memory. However, with the step from 9x to NT, this thing became obsolete and thus all these tutorials became useless on NT-based systems.


At least that is what most people (the more stupid ones) thought.


In reality, programs still need to copy memory blocks and just the actual shape of how they do it changed, but not the fact that memory copying still takes place. So the people with more than a drip of grey matter inside their heads were still able to draw benefits from these tutorials, because the really essential thing about tutorials is not the current target, but THE BASIC IDEAS they convey.

And here comes the tough thing... there is so much to read and learn that you can spend your whole lifetime with it. So you will need to specialize in a particular field. However, just like with university, you will need a rather broad basis of fundamental skills to get an idea of what you are doing and how to approach a particular problem.

Apart from tutorials which will give you very special but also limited views on certain topics, it is strongly recommended to read at least a few books about the inner workings of your target platform. It is e.g. essential to learn about how things like inter-process communication, process and memory management, etc. work.

We all started out crawling before we started walking, so you will have to face that teething (and teething problems) are vital for learning and gathering knowledge. We can't help you any further than pointing out what you have to do for a start, you have to *learn* it yourself. We can't do your work.

special thanks goes to laola for brief and precise essay. thanks a lot joe. it was quite helpful. and u are right i will have to start slowly. i will check out the peid stuff.

I have already crack the zip files password with a plaintext file that i have found in the cd also (was very lucky) ......
basicly the key file was for the demo version but i ran a cross checked with original file, and found out that the software will only ask for the dongle check if implemented in the key file. Demo key file dont ask for the dongle and is full version. except for the registed name. the problem here is that the key file encryted.

there are two file that make it full; one is normal plaintext, one more is encryted. both will be check by the software for security. any adjustment that is not the same will not start the app.

i need to decrypt the file. any body willing to help or guide me please PM or post a message here.

If you can finish this, I really think you'r not a newbie anymore.

I even dream I can do as you.

I haven't touch the dongle.

Here we have 2 page thread, and you're making progress, even though, not really getting much more than finding easter eggs on the install disk, you haven't even told us what kind of dongle you're dealing with, what in the heck is it? Since it has a ??????.dat file I'm guessing FlexLM, that could expand your options considerably, but you haven't even given us that much info.

SiGiNT

well it is a nkeyper dongle (usb)

by the way here is the full detail that i have found so far

sorry long time no see coz been busy reading up and the site when off for a few days. let you all know on the update asap.

I'll have to read up on that one, it's a new one on me - why split your question into 2 different threads - yes I agree it shifted gears to encryption, but keeping it all in one thread gives a better picture of what you are doing - and we really shouldn't have to pry the info out of you! it's to your benefit to let us know as much as possible, that way we get and better picture of your problem and can help you more efficiently.
