Ionut - in addition to what Larry and Victor have said -
there is a chinese thingie floating around called UnFoxAll that completely defeats all ReFox encoding schemes, and recently the Xise schemes as well.

I've got it floating around here - its a verra nasty thing - and I should probably translate the docs into English just to pass it around ..
I HATE UnFoxAll, found out about it my first trip to BeiJing in 99 - and got a copy, studied it, and started yet another righteous code hack.
I've got something that UnFoxAll can't decompile - but I'm really hesitant to release it anywhere except in my own works.

I'll say this much - if you ever studied cracking techniques - part of the answer is there ... Also - UnFoxAll came about because of a tort case from MS filed in Shanghai against a Chinese computer reseller - seems they were giving away the OS and FoxPro/W 2.5 back in 94 ... so some of the staff of that defunct Chinese company got together, got some boys from Tsinghua University, and made UnFoxAll .
