Real Understanding Of Serial Generation

some online-checks can be keygened.

Some progs go online only to get some activation info then write it to registry or files. When they starts, they just check the activation info from registry/files. An offline-keygen can generate the desired activation info and directly write it into registry/files.

you are talking about CuteFTP 6 well this type... but not the type who checks every time you go online.

Yes, this is one kind of online-check : in this case, the real check is done by the prog itself, and the server is only needed to provide somme infos. So, it's often easy to emulate a false server's answerd by patching the prog.

But it's another story when the prog ask the server to do some real job, sending to him the local infos. Here, it's the server wich do the check, and if you don't give the right key, you remain off... That's the case of many trading softs witch needs to use fresh quotes for sample. Basically, it's like a simple ftp : without psw, no entry !

a little bit off-topic, new InstallShield uses RPC (through ISScriptBridge.dll) to call custom script functions, and "setup.inx" uses new file format so old script decompilers are useless.

I was refering to the programs that create the scripts, not the scripts themselves.
