What is serial number and why you need itSome programs give you limited functionality untill you register them by entering a special string.This string is called serial number. Our site has lots of them.

Just enter the program you are looking the numberfor and press search button. Then select the found item in the list and you will go to a page where it is possibleto show the serial number or download crack/keygen for it.What is keygen and how it is usedKeygen is a small program used to generate serials number for software.To use it you should download the archive, unpack and run the executable file.You will see a window and there will be a button Generate. Press it and the serial number for the desiredsoftware will be generated.What is crack and how you can use itKeygen is a small program used to change the software in such a way it won't ask youfor serial numbers anymore.

I have seen them plenty of times, with many different types of software, but the one thing I have always wondered, is how software keygens know what key to generate. I know the basic principle of it: the keygen looks somewhere in the software installation files and creates a key that matches some encrypted file which allows the program to work. But I wanted to know how they do that, and how to prevent it. This is really a multiple part question. How does the key-system work?. How do programmers usually create software that works based on a key.
I am an intermediate programmer, but I never learned much of the security/anti-piracy aspect of it. How does the key-system work?Well it depends there are many implementations. One of them was discussed in:Assuming you don't want to do a special build for each user, then:.
Generate yourself a secret key for the product. Take the user's name. Concatentate the users name and the secret key and hash with (for example) SHA1.
Unpack the SHA1 hash as an alphanumeric string. This is the individual user's 'Product Key'. Within the program, do the same hash, and compare with the product key. If equal, OK.Note: every key scheme can be cracked.
That's why a lot of tools use online validation. Where does it usually look to find this 'encrypted file'?There usually is no encrypted file when using the previous method. There might be other methods to generate keys with another algorithm, but they never store all keys in the program. What do the companies do to encrypt that file?Well if you are referring to storing the key the user typed in your system, then sometimes it's saved plaintext in a config file. Sometimes they use symetric (like AES) encryption with a hardcoded key to encrypt this file. What method is the keygen using to create the key?Because there are people that can figure out the scheme the program uses and just implement it in their own keygen. What measures can companies take to prevent the use of keygens in pirated software?Online activation, but the harder you make it for the customer to use the software the less likely you they will buy it.
In the end there isn't a single piece of software that is piracy-proof. If there was, companies like Adobe and Microsoft would be hiring you instantly. Serial numbers for computer software have a specific pattern, which allows the installer or application to detect whether or not it is a legit key. A very simple example would be that every serial number has exactly three occurances of the number 5 in it - so 1932-1253-2319-5512 would be a working serial number. In a real-life scenario the relationships between the numbers would of course be more complicated.The shipped software contains an algorithm that checks whether or not a serial is valid. The software creator has a piece of software that allows him to create serial numbers for the product.To create a keygen, a cracker group (people specialized in breaking copy protection schemes) analyze the program executable to find the part that checks the serial. They then reconstruct the algorithm to create the serials based on the checking code.
The finished keygen is an app applying the algorithm to create a serial number.Sometimes keygens do not really contain the algorithm, but rather a list of valid serial numbers, of which one is selected at random.The keygen for Windows xp in the later service packs was more complicated, because Microsoft checked not only whether a key was valid, but also whether it had been sold with a copy and was not already in use on another computer. The keygen sent mass requests to the Microsoft server to check whether or not it was a working key. How does the key-system work?In most common form if (some-complex-or-not conditions-here) then (OK). Complexity of checked condition limited only by your fantasyWhere does it usually look to find this 'encrypted file'?There are not any common patterns, where and how store and read this information. Well first of all I'd suggest you to stop seeing those keygen files, as they are hacked piece of softwares (mostly/sometimes) accompanied with some other non-harmful looking image/nfo/lnk files which in full capacity of the hackers/crackers intentions could be crafted especially to infect your machine itself.You might have heard of img/lnk/other files infecting boxes just when Explorer tries to access it. Then there are keygens being binary themselves which are supposed to execute and perform any stuff on your box, right.Now, for your Queries.You gotta understand, there is no global specificfile/memory-location/etc thing to go for.Designing a keygen for software has two main basic ways:.
