Hi all!I've a simple question i think.Maybe somebody could help me.So the question is:How can i convert a name to bignum in delphi with FGInt unit?

Exactly what do you mean with "convert a name to bignum"? I can sorta guess what you mean, and in that case it is most likely something of a misunderstanding, but go ahead and prove me wrong.

dELTA! Like <the program I want to crack> does.

Ok, so I guess that once again, my mind reading powers were right...

What you want to know is most likely how to generate a correct serial for a certain name, for the software you mention.

First of all, you cannot just "convert" a name to a number. There are infinitely many ways to generate a serial from a name, and most of them do not include bignum-libraries for that matter. You must disassemble/debug your target program, and analyze the algorithm they use. If you're lucky and it's a bad design, you will also be able to fish a serial directly out of the memory of the program, without actually knowing anything about the algo.

I suggest you start reading tutorials about serial protections, serial fishing, keygenning and such, to get a better understanding about this topic.

I also strongly suggest that you read the FAQ for this board before posting again, so you don't happen to make a crack request and I'll have to delete your thread. Also, you shouldn't post the name of your target, so I edited it out in your post above.

That wasnt a crack request... And if you can fish a serial from a 255 bit RSA then you are the king. DD

Well, if you could "convert a name" to a valid RSA key you wouldn't be half bad yourself I guess...

And if you would read the FAQ listed in the BIG RED LETTERS you might actually have a better idea about how you are supposed to ask a question and what you are supposed to do before you ask.

So far, mostly what you've done is violate those rules.
