Not too much to say about but let the following be a storyline of the challenge: "This program is believed to be used to check validity of superheroes' secret passwords." Your objective is to analyze the program and find the secret passswords. It's up to you if you want to submit your answer here or via PM to me. It will be up for a week then I will post my detailed solving method. Enjoy it! OldSkewl.zip

Hello everyone, Here's my new KGM challenge for learners. As the name suggest this is a puzzle and I guess to solve this you must have some knowledge about something I will not reveal here what knowledge. Try yourself to find it One more thing, if you try to patch this KGM, you have to understand it else it will warn you A valid submission is: 1. Only a keygen coded on your own. Rules 1. No brute force, no code ripping or patching If you have some time write a nice tutorial explaining the method and technique used inside. Puzzler KeygenMe #fixed.zip

You need to make it accept not valid username and userkey. When you run the app first select cracktest.exe as a program and than fill in username and userkey and than click run program. If it says "sorry invalid vip member" than you are failed and if it says something like "valid" and closes itself than you have successfully bypassed the login check. You need to upload the cracked bin to prove it that you have cracked it. Rate the difficulty level. Good Luck. delphicrackmehard.rar
