.Net ghost lol.

Give me a minute or too, ill see if I can do it.

EDIT: Correct me if im wrong, it combines user and serial to get a final output of an encrypted Rijndael text?

ok this is bad crack me
bcz i need to give a string / int to decypt
ur byte .... and it can be anything
and in fail u just show me a label
u dont compare nothing
so this cant be a crack me
call it decrypt me ...

if you are so good, why don't you crack it?

[DragQueen]

i dont know what username he use to crypt his byte[]
funny isnt ? and i dont know what word length he use
so how u plan to crack it ?
and the genious use reflection to load his byte
so on fail byte decrypt u go into catch section
and u see label ... Oh funny one

Hey I just woke up. Wanted to know how your making out :)

[Nazworth]

This is not a CrackMe. It is more a bruteforce me as nothing else is possible. That does not mean that it is special good or something it does just mean that it is impossible to do without brute-forcing.

You have a point Mr. pr0t0typ3 :)

[idonotcare]

So am i right that as long as he doesnt gives the data our with which he encrypted it ( Username & Serial ) its not "Crack" able?
So the first time you sell it on the marketplace it will be crackable again? :)

Correct me if i am wrong.

Yes, you can't crack this without the key. There is a way to do it, but it's extremely difficult.

Anti-KObac XD hahahah damn funny

[Nazworth]

Why can't you just patch the encryption code?

Because it won't work. You can try, but It won't decrypt it correct.

[Nazworth]

So what you're saying is that the rest of the program is encrypted, and when you log in correctly, it decrypts it? If that's true, the key is there.

Or is the User/HWID is used to decrypt the data?

Nothing is uncrackable.

Yes nothing is uncrackable, No one will be able to Brute force the key is a reasonable amount of time, and The Username & Serial is not stored in the application itself.

[1337x1337]

The username and password (which is unknown is used as a decryption key for the appliction which will be invoked after you decrypted it using the write key)

I also know a program what is using this way, it's called Prevx Anti-virus, i tryed to debug it and some other ways but it's realy good protected. (I'm a beginner @ cracking)

lol. ill give it a try.

right now i just see - CodeDom,DES & Rijndael Enecryptions.

nice shit :)

hope to find something...

Bro, you wont get it when kobac & proto didn't
All you need is 1 valid login to crack the app but since this guy isnt going to give some usernames + serials out you cant crack it^^

Its not even a secure protection since the only thing you need is 1 valid login to crack it.
( Correct me if i am wrong )
