Поиск алгоритма генерации ключа

romoga · 3 дек 2008

Доброго здравия всем. Имеется кейген. Распаковал, открыл в ида. Нашел участок где генерируется ключ в зависимости от введенных данных, но неману с ним совладать. Код в любом случаее в отимизированном виде. Как переделать в обычный ? Что Посоветуете ??

хорош флудить.

wsd · 3 дек 2008

romoga
для этого есть тег СODE

romoga · 3 дек 2008

ни пинайте что отдельно не выложил... тока правила дочитал....
так вот в генерируемом ключе который состоит из трех блоков символов.. первый блок символов
делает эта подпрограмма.
если логин = 0000
и пароль =0000
то ключ=VTNWGCJQPAO3GAEKD24000000
з.ы. мне ненужно делать свой кейген, хочу понять смысл генерации этого

То, что ты привел, сильно смахивает на стандартную функцию memcpy

romoga · 3 дек 2008

извините еще раз за длинный код...

only · 3 дек 2008

сори оффтоп почищен

wsd · 3 дек 2008

romoga

извините еще раз за длинный код...
Нажмите, чтобы раскрыть...

так ты его отредактируй!
в тег CODE засунь

И даже не напоминает, а это она и есть. Приведенный тобой код просто копирует arg_8 bytes from arg_4 to arg_0.

romoga Воспользуйся Hex-Rays'ом, натрави на этот участок

romoga · 3 дек 2008

на этот участок хекс рейс ругается invalid basi block
а на третью функцию в которой я думаю третий блок ключа генерица выдает вот это
