maxodrom1 on 1:16 PM 12/22/2022: Quite easy. The valid key would be "t123-" , and the only thing that matters is the "t" and the "-" can be until 9 characters total, for example "t123-4567" or "t435-ftgr" or "tgth-" etc...

2ourc3 on 1:01 PM 01/01/2023: @Suasaki: Patching isn't part of the solution except if especially mentioned. On the other hand, the goal of this chall is to find the criteria of a valid key in order to produce other. Thanks for your feedback, enjoy the other chall coming :)

NisheshTyagi on 12:31 PM 06/12/2023: keygen in python:- import random import string #created by NisheshTyagi def generateKeys(): letters = string.ascii_lowercase keys = [] while len(keys) != 5: key = 't' for i in range(8): if len(key) == 4: key += '-' else: key += letters[random.randint(0,25)] keys.append(key) return keys

iwn on 9:46 AM 10/23/2024: SPOILER else if ( user_input[0] == 116 && user_input[4] == 45 ) figured they were ascii characters. found it and the first character had to be a 't' and the fifth a hyphen.

iwn on 10:04 AM 10/23/2024: keygen import string, random chars, key = string.ascii_letters + string.digits, "" for i in range(random.randint(4, 9)): key += random.choice(chars) key = 't' + key[1:4] + '-' + key[5:] print(key)
