Key Generators

[mogar]

I have a good friend whos wife's cousin would like to know how a key generator works?
For expample, a downloaded key generator for a particual software is opened up and then it goes to msdos window for split second and then disapears.
Can anybody help this poor, dumb, person out? ;)

that doesn't sound much like a keygen to me...

where did they get the keygen from and do they have an updated anti virus installed?

Keygens do something like generate a random number based on a mathmatical template which is derived from the serial of paticular software :unsure:

As for your Keygen I would suggest either try and break down what the keygen is trying to run in MS-DOS or just find another...

Yeah.. that sounds more like a batch file than a keygen.

[Illuminati]

A keygen simulates the generation of a valid key by simulating/following the algorithms that would be used as validation by the program's registration system.

e.g. If a program you were looking for needed a registration code of a 3-digit code that was divisible by three as well as a vowel at the front, you could get a keygen to find a code like "E417" and use that to register the program.

Often 'keygenerators' are not generators at all, but a bunch of keys that are randomnly shown.

BTW: that MS-Dos window thing sounds a LOT like a dialer or trojan horse.
Be very careful with keygens as they can contain viruses and such. Always run a good anti-virus and firewall

If it unlocked the programme it's a "patch".

[ThePlasticSurgeon]

If you want to view the text output of a Microsoft Disk Operating System Program then do the following: Execute the file cmd.exe/command.com*
Navigate to the directory with the executable file you wish to investigate**
Execute the executable file using the command interpreter
The output should remain visible in the command interpreter after the program execution

To create a keygen*** a person attempts to input a key into said program whilst analysing the data in ram. The assembly code held in the ram at that point in time should allow someone to work out how a key is checked using that program. Some programs also attempt to patch the executable file of the program itself (to override the registration). I reccommend you scan files for viruses before you execute them.


*cmd.exe should be used for Microsoft Windows 2000/XP and command.com for previous versions.
**To do this type "<span style='color:blue'>CD X:&#092;" into the command interpeter (where X:&#092; is the directory containing the specific executable)
***Remember to use keygens only for software you have legally purchased registration codes for.</span>

So, a fake Keygenerator?
