Whitebox crypto crackme ?

Post by OHPen »

Hi,

does anybody know a small / very small example crackme which has a simple implementation of a whiteboxes crypto algo. Cryptoalgorithm doesn't matter.

I'm more interessted in the whitebox stuff.

If somebody can supply such an example I would be glad to take a look at it.

Regards,
OHPen

PS: I need it for a bigger whitebox example I'm currently doing some research on it.

For Java obfuscation, check out the sandmark suite.

Hey,

thank you for the hint. But I'm not interested in obfuscation, the more I'm interested in Whitebox-Cryptography and the attacks on it. Thats why I'm try to collect different Crackmes or other implementations to get a feeling for it.
I took a look at the link above, but afaik i already had a look in this crackme, which is originally from cloakware right ?

Regardíng Sandmark. I know that framework already from some research years ago. Its a very sophisticated library which is rather powerfull. For everyon which is interested in cracking java applications or writing deobfuscators or even obfuscator this, is a must look!

OHPen.
