    My first crack me and my "first" C++ app(I have made dlls before but not exe). http://www.mattsbox.co.uk/high6/Files/crackme1.rar crackme1.rar Have fun . If you think you have it check the hint first. Hint: The messagebox is a fake .(the correct password doesn't have a messagebox popup) Note: Not packed. Hint2: There are over 100 jumps and over 200 calls to assemble the password.

    Soda mailed me to tell me ASProtect 2.3 SKE was listed in a tutorial on the site but the unpackme was not listed in the unpackme's. Seems that since the change over to the new site layout it got removed For those interested in it you can find it here: http://www.tuts4you.com/download.php?view.1684 I'll have to double check and make sure there are no others that slipped past during the site update...

    GOAL: Goal is to register the ReverseMe. This is visualised if it says at startup "REGISTERED to:" followed by the name you registered it for. ABOUT: Mostly byte coded in assembler (masm). Not packed. You may either patch, fish or keygen. More info in About box. Obviously, no aesthetic-patching-only allowed. INFO: It's not the algo that makes the challenge! The algo is short and easy, the real challenge lies in the obfuscation and stuff! I take my hat off and bow deep for those bringing a valid solution! Please explain how you did it. MORE INFO: On a sidenote: it was also a challenge for me as I had never byte coded such a long part in one target. Don't be surprised when…

    Ok, here it is - easy VB6 coding, easy upx packed.. only one RULE: - no cracking/patching, just *fish* for it This is my first fishme so dont be dissapointed if it's too easy, its good to practice, right :?) serialFishMe_byChupaChu.zip *there are many solutions possible for this one* so keygening it could be a challange also - but then you must write a tutorial for this one Have a nice day!
