Description

This contains a secret message(in plain text- that's not the challenge). You have to type in a code that satisfies certain checks to print the message. You have to find a valid code to crack this crackme. Note: 1. You are allowed to patch the crackme only for reverse engineering and debugging easiness. 2. A 'valid code' is a code that when given to an unpatched version of program, should print the secret message.

ali0gamer on 9:48 AM 03/06/2021: Thank you for the challenge. I used python to generate valid keys but i have to run the application couple of times until it prints the success message

pranav on 9:12 AM 03/11/2021: ali0gamer please post a solution writeup

ignjat on 10:40 AM 03/25/2021: The program sometimes doesn't give any output. Is this on purpose? I waisted a bunch of time trying to figure out why my python script wasnt working...

pranav on 3:11 PM 03/28/2021: This is an older crackme, which is not actively supported.. anyway, yes it can sometimes fail, but not always.. It's a side effect of my early anti debugger.. but most of the cases it should be fine.. message me on pranavappu007 at the discord server on crackmes.one, if you want more help.

pranav on 3:12 PM 03/28/2021: and for all yes, you are allowed to patch out the anti-debugger if it is failing to work properly..
