    Hello, everyone! I hope the thread title caught your eye. I want to present my first keygenme in quite a while. This one is a departure from the past iterations. The main goal with this "series" (I plan to have more along this mantra) is to help ease novices and noobs into the art of reversing (patching, keygenning, etc.). I hope that you guys will solve this and provide tutorials. Hopefully, the tutorials will be spread around the Internet for all new people to enjoy and learn from. Features of this keygenme: Coded in MASM (with the aid of WinStudio) Packed with UPX Starting nag Ending nag Disabled textbox Disabled button No cryptos Somewhat frustrati…

    I've never seen x64 KeygenMes before, so I thought why not write one. This is my first x64 code. I hope there are no bugs. I kept the algo fairly simple and wrote it in MASM. Rules: - No patching! - No bruteforcing in keygen! Since there aren't any great x64 debuggers available, please tell me what debugger you used to solve this, so I could get a small overview of what people use for debugging x64 code. In case you don't know what debugger to use, I'll give you a starting point. Consider using FDBG. It's also the debugger I used to test this KGM. Good Luck! KeygenMe x64.zip
