To help you, you can read the solution to my 3rd ckme.
As some part are similar.

i unpacked it, i found it interesting...similar to telock and something like that now i'm trying to write a keygen.
15. Sep 2007
very nice... I'm really impatient to read your solution.

Yes, you're right some idea provides from telock, but with less efficiency, i think.

I'm already working on crackme#5, which will be packed too, but this time i'll try to make it harder than this one.
16. Sep 2007
As you also know, i'll write a solution as soon as i can...unpack was interesting and also keygen is simple to do!

Nice work red477 and nice solution.
Well you know, i'm a newbie in protector coding too ;)
And you're right, too much well known trick...

But, i will do all my best to give you a more interresting challenge in #5.

Again, well done.
