Do not forget about the programs suggest incomplete functional - DEMO. It is not broken.

What about in the case of a piece of software without a serial algo. For example one that submits a serial code for a server, which returns a value (1 or 0 for example) as to whether it's valid. In this case the entire algo is on the server and there is no possible way to determine what it is, unless you can get access to the server, which is no longer Reverse Engineering and becomes hacking/cracking, and therefore the only possible way to Reverse the program is to simply patch the server check.

@Flatline Now tats exactly wat sim said
@greengo if the developer not included code for spefic function in demo surely cant broken by patch or keygen or anything else too.

Did I miss something :confused: I thought sim had said everything can be keygenned and that sometime however you may need to use patch AND keygen. I was talking about only using patch as not being able to keygen since there is no algo built into program
