The Bat! got keygened
 

After keygening WinRAR, now SeVeN has keygened The Bat!. I think it is using ECDSA-800. It seems he has found a new way to factor the numbers or bought a super-computer ;)

P.S: I don't know much about grid computing

Is it really significant how it was made? You can see this nice release, anything else is a mystery.

Yes, it is very interesting how it was made. It seems the hole exists in the key generation scheme. Anyway, it is great results.

Well anytime a program has gone without a major break in their registration security, (Total Commander, Winrar, etc...) everyone is naturally curious in general, especially if SeVeN found a new attack style on ECDSA or just how in general he did it. Such a tutorial would be an amazing read, but will probably never happen.

I think SeVeN will not give this information. This topic will be a second flood-topic like WinRar with stupid thanx. My post means only that.

Even if exist new style attack on ECDSA, you can not use this technology as your own. So, right way try to find and work hard on another attack. There many examples (ASProtect keygens by TMG & ECLiPSE, RSA protected apps breaked with grids, etc.)

I agree my friend. I was only attempting to explain nanobit's curiosity.

SeVeN is great keygenner :)

I didn't start this thread as a "thanx" one for the keygen. I just wanted everybody to know that ECDSA is defeated AGAIN, and that's not something unnoticeable.

I wish 1536-bit RSA to be vulnerable also, but :(...

I don't think that ECDSA is vulnerable. IMHO, it was attack on implementation.
p.s. Forget about hasp, man :)

ECDSA-800
 

Thank you for your observations, what do you mean by ECDSA-800? Could you please explain in detail what ECDSA-800 is?

http://en.wikipedia.org/wiki/Elliptic_Curve_DSA

And its key has a length of 800 bits.

The Bat! has NID_sect163k1 curve (NIST curve over a 163 bit prime field). I saw a maximum recommended 571 bit prime field. Never heard of 800 bit keys when it comes to Elliptic Curves.

Is SeVeN think that exetools members has not enough persion for get his method?

for user that got download problem:

It's amazing :). Some years ago I wrote keygens for TheBat 2 and 3, but I have used my own private key to generate licence and replace original public key with mine. I attach source code of tbkg3 (it's history). The algorithm is in keygen.cpp.
