Hey Steve,
I got the very same inquiry. I highly assume it was the same person. Quite unbelievable. I also tols him that only original software is acceptable. I don´t want to help spreading my tools in the warez community. Also my italian reseller had some orders with the 12345 serial number ending, also rejected them. That´s the only way to handle this imo.

I know it's not directly a Maxon issue, but right now it's about
50% of the R11 users that runs "12345"…….Cheers

I know, it gets more and more. Each day at least two of them want to buy my stuff, too. And a surprisingly big amount of these people even register with their company email address. How stupid can they get?
Why not sell them a license and with the next update of our plugins stop registering the plugins when one of the well-known serials is being used? Wouldn't that be legitimate
Cheers,

or create a function that formats the harddisk if the serial is found (if that works from a cinemaplugin)
but i guess that could make trouble, too. -

Don't even think of that.
This is straight against the law and you will be punished heavily for such a thing.

I agree. Damaging their machine is definitely not a solution.
But still, how about blocking known crack serials with a later update of the plugin? -

Nobody can force you to sell an upgrade.

The order form of my online shop and also the form for requesting a new plugin serial due to a c4d upgrade doesn't accept illegal serial numbers any more, so I'm not bothered with this topic any more. The database of the illegal digits is updated automatically: there is periodical check of all c4d digits in my purchase database. If a serial number occurs more than three times, it will be transfered to the black list.

That sounds like a good idea.
I'll implement that for my license software, too. -

Hi,
not exactly related to serials, but :
I'm actually thinking about beefing up my protection a little bit, while not putting too much effort in it.
Is there a function in the API to compute file checksums like crc or md5 ? -

i don't think so.... but i think you can implemnt it by yoursef via an external lib.
good idea

Try this one:
http://256.com/sources/md5/But actually, using MD5 is probably not a brilliant idea. I guess you would mess a bit with the user's serial number, then digest it with MD5 to get the serial key. In your plugins, you would do the same again and then compare the result with the user's serial key.
That means you have the complete algorithm TO CREATE serial keys in your plugin, making it easy for a cracker to extract that code and make a key generator. I would rather recommend some asymmetric algorithm, like Blowfish. That way you can compile the Decrypt function into your plugin but not include the Encrypt function (which you would only include in your own license generator).
Anyway, if somebody really wants to crack you protection, they'll do it. IMO there's no secure way to prevent it. -

thanks guys, got it already
Using a md5 algo now that i can bytewise feed with BaseFile::ReadByte() , seems to work quite well!

Hi Jack,
actually i dont want to change my serial with this. I noticed my plugins get cracked, so i just want to detect if the files were changed, using the md5 checksum.
About the keygen code extraction , i know what you mean, but then there's the possibility of asymetric encryption. Not sure if I'll go so far though..
I think I'll try a couple things and see if the situation changes.

yeah of course, I just want to make the crackers life a little bit harder, maybe he'll lose interest when it costs him too much time
