Description

Hi everyone! This challenge is quite easy, find the valid keys to get the pass. The goal is to write a little keygen that can generate valid key for the challenge, try to not bypass this logic, even if it is more simple. But aim to understand the condition required to obtain a valid key Have fun! Made by 2ourc3 ( https://www.bushido-sec.com/ )

And for some reason you have to introduce it 3 times before you get the password

Phil on 5:09 PM 02/27/2023: Don't know why one of the comments say the 3. and 7. must be an X. It adds 3 and 7 to the counter and checking for an "-". First one must be an A, 4. an "-" and 8. an "-" and ist has the lenght of 11.

iwn on 10:25 AM 10/23/2024: take a look at this compiled code to find out the valid format: if ( (unsigned int)strlen(localkey) == 11 ) { if ( *localkey == 65 && localkey[3] == 45 && localkey[7] == 45 ) {
