Blepperton on 2021-11-19 05:16: Program gets stuck in infinite loop when typing "a".

Blepperton on 2021-11-19 05:19: Using random numbers in a crackme is really not that great. You should give a time window where the number stays the same or something. Cheers.

Blepperton on 2021-11-19 05:24: We take back whatever I said ^^^^^ there. Your implementation modulos the random number. nice crackme.

Slava on 2021-11-23 03:57: you have to look at the debugger to get the values, since you are using random numbers, even though you modulus it to 10000 there's still no "fixed" solution

spoo on 2021-11-23 05:43: To prevent confusion for future comment readers: There is a fixed solution. Pseudo-random is NOT random.

TrollZik on 2021-11-26 19:48: That was a huge hint. I have just noticed that your rand calls produce, after manipulation, the numbers 2A and 2114. Added them with win calc.

th3h3d on 2021-11-27 02:54: it generates random number for each time but it is not a really random number so if you enter fist time, your password is 8510, if you type something wrong, you need to find out second generated number and if you still type it wrong, now num is changed again and you need find third generated number and it goes like that...

th3h3d on 2021-11-27 03:01: some generated nums: 1. entering: 8510 2. entering: 12836 3. entering: 14895 4. entering: 10838 5. entering: 11428 etc..

R3tr0BS on 2021-12-01 12:49: i really liked that you added 69420 option, easy, and learning experience. :)

2347832947284792374824 on 2022-04-07 01:29: what is the rar password?

Kutch on 2022-04-30 05:36: Because there is no seed provided for the random number generation, the number is always the same. You can easily just write a script which gets two random numbers modulos 10000 + 1 and adds them together and there you have the result.

jinzi0113@163.com on 2022-10-18 08:41: The sum of two random numbers up to 10,000

An extensive writeup with reversed code examples, a keygen and more.

Can be read as a txt file as well. Just change the extension to `.txt`.
