Although there are several generations of subsequent DES cracking hardware developed by other teams (albeit not with the level of open hardware detail as Deep Crack!). https://www.copacobana.org/docs.html https://www.copacobana.org/docs.html https://crack.sh/ https://crack.sh/ (I'm a little confused at why crack.sh had to spend roughly as much money per key per second as Copacobana, when it was being built with a more advanced model of the same manufacturer's FPGAs around a decade later. I wonder if the Virtex-6 has some high-end features that crack.sh doesn't really benefit from, but still had to pay for.)
