I plan to add one of my programs:

-serial number protection
-online validation

I know the online validation is very hard to crack, but in DarkBASIC, the serial number detection method is secure?

I plan to insert to the code "the key" backgeneration method (from name its generating back the serial key, this is much easyer, than generate back from the serial number), and when the detection was sucesfull, then delete all from memory (serial number/name). Now, hard to crack this, or easy, when the program is doned in DarkBASIC?

Both are extremely easy to crack actually.

Quote: "online validation"

Easy to crack, (same process as removing the checking of a copy-protected CD in fact) since the changes to the application can be manually performed (just check out some of the 3ds Max 7 cracks to see what I mean)

Quote: "serial number protection"

Easy. One user can easily share their code with the rest of the world (the reason for M$ introducing activation to windows)

Use a serial number that is generated from your computers hardware setup, or online activation that uses lots of cryptography to encrypt all strings, variables and return variables with the key generated using a complex algorithm.

That should slow crackers down; it depends on your selling price really - is it going to be worth the effort when you can just hand over a £10/£20 note.

i plan to give everybody special serial codes, generated from the costumer name.
When the user buy, get the account to get patches, others (this well be a game creator program), and when they serial number does nt exist in my database, he cant enter to support area.

I will forget fixing some bugs, and without real serial number, he cant download the patch. :EVIL:

Actualy, multiple users cant use this serial number (like in Steam).
Cos this is a game creator program, the name of the user will be coded into the builded game, writing out the author's name.

JohnY: no. I thint hardware detection serial numbers are sucks. The user buy a new video accelerator, and they must get a new key. I havant time to genereate every day new serial codes

i think the "omg ned da patch" protection is better

Use a dongle like DESKey - you should be able to blag a free SDK (and it was pretty easy to program too). Unfortunately each user would need the dongle too.

Be inventive, you really can't avoid serial numbers, but don't stop there - you could generate a number, hide it somewhere on the hard drive, and work out an authorisation number from that and the username, which you would provide the key for.

A reinstall would possibly mean a new serial, but that's all that would be affected. It won't stop people cracking and distributing, but really that's a whole other threat you should consider seperately for now.

You would have to do some investigating periodically to find published serials or cracks, and possibly you'd have to threaten webmasters into removing cracks and downloads, all that while updating the software to ween out the cracks. Like you'd break a crack each time you released an update, whether it's a simple serial ignore or something more drastic, it seems to be the preferred method by internet software firms.

Thanks for help!

I think the serial+validation will be strong enough.

For a second, I thought the thread title said "What is the strongest crack?"

Make the programme check the binary data of the bit doing the serial, in multiple ways (lodged in the rest of the code) just to make it a little harder...oh wait db cant do that without external DLLs

make a 256 bit key with semi-random dummy data and place a small amount of significant data in locations that only you know about

thanks for the tips.

But the program will be gain the data from a serial key protected php generated file from the internet.
If the user have illegal key, the patches and the support (other sttuffz) will be not available.
