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 ;-) |

CInema4d plugin serial dialogs have a distinct signature, wheather in IDA PRO or OllyDBG,peexplorer,etc etc. A simple (and I mean simple) md5 sum/crypto isn't going to stop anyone intent on cracking your plugin. The best bet is to forget about the nonsense of intensly focusing on protecting your plugin/application and just have fun and reap the rewards of the legit users/purchasers. Apps like Themida/ASProtectSKE/EXECryptor etc etc only irritate legit customers because of AV/Firewall/Virus etc etc. Even Maxons reverse Modulo encryption/math etc etc system doesnt prevent dedicated crackers from Keygenning their Cinema 4D Main Application or modules. Basically in a sum, let this concern die because in the end if it can be seen/loaded on a computer it will be cracked/keygenned/loaded no matter what you do. Be creative cheers. I hope this helps you all,And good luck!!!
