Challenges are fun, and they help us to understand how effective some protection techniques are. On this page, we aim to list challenges related to key hiding in software.

    White-box DES

    A binary executable containing a white-box DES encryption operation with fixed embbeded secret key.

    The challenge was put online in 2007. Two attacks surfaced almost at the same time, independently from each other
    • January 2012, James Muir
    • January 2012, Sysk. Attack has been published in Phrack. See http://phrack.org.
    The challenge has now been accomplished and is hence offline.

At this point, I have no challenges online that I have created myself. But if you are aware of other challenges, don't hesitate to let me know, such that I can include a pointer here.
