Here, it has been raining since yesterday evening. Maybe it's the weather in combination with the "friday syndrome", don't kno', but for the past 2 hours, I have been staring at the trees through the window visualizing MY liquid supper. My colleges - hopefully - think I am solving an incredible difficult coding problem... Ah, Belgian trappist,... dark..mysterious..inspiring..sweet with a bitter aftertaste..here I come... (Have a nice weekend

Like everybody here points out - as frustrating :mad: as this may be - there is no crack-proof software or security. Protecting software is as difficult as protecting a "bit stream" (cfr DVD, DECSS, ...). If it's 'ones and zeros', it can be copied, dissected, cracked and altered. That does not mean you do not have to try, as Shane Hyde implies. Maybe a third party library can do the trick. Our company uses "Sheriff software" :eek: (http://www.sheriff-software.com) which is relatively cheap and offers in my opinion an acceptable level of protection. (NB: Please note that this is not a sales speech) I tested the library and it is possible to crack at least a part of it. (NB2: So this is definitely NOT a sales speech) It depends on the license policy you use. If you automatically issue a "fully functional for a limited time" evaluation licenses you are more vulnerable to an attack. I did not exhaustively test :cool: the key generation scheme but it 'seems' robust enough. At least a third party software library might be the answer since they are (hopefully) constantly improving their product, and they are more focused and putting more effort into the software security design goal than you and me have time for. Just my 2 cents. NB3: These Board Emoticons :rolleyes: are cool !

>> Again, none of this will prevent a determined cracker, or even a half-good one. Agreed, but what you suggest is cracked in 10 minutes, using RegSnap, RegMon and Regedit. (We use a third party copy protection scheme, which I eh... tested). It uses encrypted keys which also contain some of the information about the type of the license (time/user limited - trial or full version, etc...). Althoug I did not remove the key's encryption protection, I was always able to fool the program in extending (renewing) the evaluation time/license. I do not have an adequate answer to this problem, but maybe it is still worthwile to invest in a good third party protection program (And try to break the security yourself when you are evaluating the product so you have an idea how difficult it is for a thief to rob you from your bread and butter)
