Nie mogę za długo robić tego samego, bo dopada mnie depresyjne znudzenie, dlatego jakiś czas temu zainteresowałem się tematem rozkodowania radia w samochodach.

O jakie rozkodowanie chodzi? O takie, że jak Ci padnie akumulator to niektóre radioodtwarzacze poproszą o kod odblokowujący radio, który w ASO sprzedadzą Ci z uśmiechem na twarzy za kilkaset złotych…

Na pierwszy rzut poszedł generator kodu radia dla samochodów Renault i Dacia. Do wygenerowania kodu odblokowującego radioodbiornik wymagane jest podanie tzw. pre-code.

Na stronie znajdziesz prosty tutorial, prowadzący krok po kroku jak odblokować radio w samochodzie:

Jak uzyskać pre-code dla Renault lub Dacii?
Jak wygenerować kod odblokowujący radioodbiornik?
Jak wprowadzić kod odblokowujący radio?

Dostępna jest również wersja angielska dekodera radia, ale to was pewnie mało obchodzi.

Aktywne prace nad moim obfuskatorem dla Javy, czyli JObfuscatorem doprowadziły do poprawienia drobnych błędów i rozszerzenia funkcjonalności.

Historia silnika

v1.03 – 31.07.2021

Niektóre wartości typu integer nie były poprawnie ekstrahowane dla strategii obfuskacyjnej polegającej na przenoszeniu wartości liczbowych do tablic
Wielopoziomowa obfuskacja wyekstrahowanych wartości liczbowych do tablic (do losowej liczby tablic, o typach double i integer)

Jak prezentują się wprowadzone zmiany do silnika obfuskatora?
