Description

Lets pretend you just downloaded a program called encryprion kira to crack encryption, but it asks you for your name and the matching password so you can use it. Your goal is to write a keygen, so you can access this awesome program. Patching is not a viable solution. In case of problems dm me on discord: TLOD#0882 Enjoy!

aolvos on 12:07 PM 06/07/2021: hmm.. looks like key depends on a system time, cause 4epuxa's login info isn't always accepted. very interesting keygenme!

aolvos on 8:19 AM 06/09/2021: Yep! i was right. program generates random seed [1..5] on startup. that's why there're 4 passwords for 1 username. i almost finished working on keygen, will post solution soon) here is an example: [login info] username: aolvos password #1: 68827 password #2: 394198659 password #3: 205588 password #4: 301

xmaple555 on 5:50 PM 06/22/2021: it is not difficult, but too long. and using time() and mod srand() cause me inconvenient that i need to input username and password instantly after i run my write-up program.

TLOD on 4:18 PM 06/23/2021: xmaple555 do you don't have to input it instantly
