Request for EZCD x86 unpack Tutorial

[mr.exodia]

Sleeping is more important than reversing this app... Regardless, every Armadillo app always calculates all hardware id types from what I know.

That tutorial is also a bit shit, but the LocalAlloc method was only to locate the 'certificate' functions (ReadByte, ReadWord, ReadDword). It might make more sense to try to follow along with what AKT is doing to see how it works (you can always do it on some unpackme later to learn how it works better).

The relevant (terrible) code for the ECDSA_Replace plugin starts at https://github.com/mrexodia/akt/blob/master/plugins/Arma_InlineHelper_Plugin_ECDSA_Replace/src/main.cpp#L115

Basically what the plugin does is hook that function, wait until a certain DWORD is found (part of the project ID I believe) and it will then just alter the ASCII of the ECDSA parameters before it's read into BigNumbers. This is similar how the 'certificates' tab of AKT works, but then it reads instead of writes.

Note that you cannot register EZ CD through their registration dialog (probably it calls their server/does validation or something). You can use the EnableRegister plugin and call "ezcd.exe REGISTER" from the command line to get the stock Armadillo registration dialog.

Mr.Exodia, you are right about the sleep, I just messed up a lot of things. Sleeping is very important.

And thanks to all your support, I got past the Registration part. Will update a video soon. It took a bit longer than expected, but I got it eventually. You've taken care of all of it didn't you? awesome

AKT is an awesome tools and it deserves good video tuts for itself, I will try whatever I can.

That Rep. is worth more than anything in my life, it brings a lot of honor to be at the receiving end and I am not sure if I am worthy of such an honor. Thank you Mr. Exodia, for making it so special. And a big big thank you for being there for me, when I need it the most.

stay awesome

Guys,

I am going to close this thread in awhile, so if anybody has got anything to ask this is the time.

EZCD is done. I was just a mere instrument and the Lords (Mr. Exodia & Mr Smiling Wolf) spend their valuable time to teach me and help me, can't thank them enough.

I still can't believe they talked to me, awesoomee

So that is it guys I will put all the good tutorials I used to learn Armadillo in one place, just let me learn a few more unpackme's.
