Hello there this is my first crack me and I'm testing my app So please crack mine app and tell me from 0-10 how hard is it and what should i make better? CrackMe #1.zip

This is a totally different approach to the other keygenMe's that I've created before but looking forward to see a keygen. if you make one give some rating between 1 and 10 of how hard it was.. and if you can show me a little video showing how u did it.. Note: make sure that you create your own keygen without using the one I provided.. the DLL is only for demo purposes and NOT to be used for a (keygen) Keygen_Me_1.5.rar

Her is are littel unpackme/enableme from me. I hope its fun for any how solve this. Level = ?? //what your thing If your unpack it can you say what tools your used to unpack it. unpackme.7z

Good day reverser ! I propose today a new crackme that has been created by me and Lollo90.Target : Silver : Create a patched executable; Gold : Create a patched,cleaned executable and reveal the correct password.Programming Language : Visual Basic .NETInfo The program was developed and protected by me and Lollo90. To test your username and your password you have to click the image on the right. A window will open, which will clearly show the success of the crack. At the start, and at the check of the password ,it can seem that is going to crash, wait some seconds and it will works perfectly.
